INITIAL SETUP & PAIRING HELP:

Quick Start Version: (Easiest 1st time pairing, earbuds remain in case)

  • To pair to your device for the first time, remove the stickers covering the charging points on both earbuds, place them into the charging case, make sure both LEDs show red, and leave the lid open.
  • Both buds will then automatically power on and enter Pairing Mode while still in the case.
  • Simply, turn on your device’s Bluetooth and look for GRIND FUEL* in your list of available Bluetooth devices.
  • Select GRIND FUEL and accept the “Pair” or “OK” prompt that appears on your screen. When pairing is complete, a voice prompt will say “connected.”

Important* In some cases you will see two product names in the available device list, be sure to select the product name that’s aligned with the headphone icon as seen below. The other option will not pair your earbuds, this is your BLE (Bluetooth Low Energy) signal that is used to link with the Tile™ app and activate your Tile™ Finding Technology.

1st Time Pairing after unboxing when removing earbuds from the case:

  • To pair to your device for the first time, remove the stickers covering the charging points on both earbuds, place them into the charging case, make sure both LEDs show red, and close the lid for 5 seconds.
  • Open the case lid and remove your earbuds.
  • You’ll first hear the Power ON tone, followed by the battery capacity voice prompt “Battery …%”. Then you will hear the voice prompt “Ready to Pair” while BOTH the LEFT and RIGHT earbuds will begin to pulse red and blue to indicate you are now in Pairing Mode.
  • Now, turn on your device’s Bluetooth and look for GRIND FUEL in your list of available Bluetooth devices.
  • Select GRIND FUEL and accept the “Pair” or “OK” prompt that appears on your screen. When pairing is complete, a voice prompt will say “connected.”

Pair to a new device: (after 1st time pairing, while earbuds are connected)

  • To pair to a new device while you are currently Powered On and connected to a device, simply press EITHER earbud button 1x and then press and hold the same button for 1 second. This will enter both earbuds into Pairing Mode.
  • The voice prompt will say “Ready to Pair”, both earbuds will pulse red/blue, and you can select “GRIND FUEL ” from the new available Bluetooth device list. Please remember to accept the prompt that will appear on your screen.

Pair to a new device: (after 1st time pairing, while earbuds are non-connected)

  • To pair to a new device, Power On both earbuds and simply disconnect the Bluetooth from the previously paired device so your earbuds are in a non-connected state. This will automatically enter both earbuds into Pairing Mode.
  • The voice prompt will say “Ready to Pair”, both earbuds will pulse red/blue, and you can select “GRIND FUEL” from the new available Bluetooth device list. Please remember to accept the prompt that will appear on your screen.

QUICK START DEFAULT USER CONTROLS

Out of the box, GRIND FUEL’s default media controls are ready to keep you connected and in control of your Bluetooth-enabled device.

We’ve also incorporated a simple feature that allows the user to hear each time they have pressed the button on their earbud, and when pressing more than one time in sequence, you will hear ascending tones to give you better control of your media. They are very subtle and do not disrupt your listening, easy to hear even while playing music, and the button response tone will help you quickly learn your way around the controls on your device.

Auto Power On & Power Off:

  • When your earbuds are in the charging case, open the lid to Auto Power On your earbuds.
  • While the earbuds are still in the case, the LEDs will turn BLUE if they are fully charged, and RED if they are still charging.
  • Remove them from the case and you will hear the Power On “pling” Tone, battery life voice prompt, and the “connected” and “Voice Control On” Voice prompts if you had previously paired and linked with the Skullcandy APP.
  • Place both earbuds back into the case, and CLOSE THE LID to power off and begin charging.

Manually Power On: Either

  • 1 second hold

Manually Power Off: Either

  • 2x press, then 1-second hold
  • Action - Press, Press, Press, and Hold 1s

SPOTIFY TAP™

We’ve partnered with Spotify to create an instant path to your music through a simple button press right out of the box.

Once you’ve paired your earbuds to your device, press and hold your LEFT bud for 1 second, you’ll hear an ascending tone and will have instant playback through your Spotify App.

Spotify Tap™: Left Bud Only

  • Press and hold 1s
  • Spotify App Required

Once paired with the Skull-iQ App and Hands-Free Voice Control is activated, you will also be able to launch Spotify and immediately begin streaming by saying, “Hey Skullcandy, Spotify”.

SHARE AUDIO:

Easily share your music or media with a friend, anytime and anywhere through our new Share Audio feature.

To Share Audio, both users must have Skull-iQ-enabled products, be in Stereo Mode (using both earbuds), and be within Bluetooth range. For best results, we recommend both users stay within 5 meters (about 15 feet) during an Audio Share session. Please also note the audio share between users may take up to 5 seconds to sync.

The person that wants to share their audio must have their earbuds connected to a device. They will press and hold the button on their RIGHT earbud for 3 seconds. A voice prompt will notify the user that they are now “Sharing Audio”. Only the user sharing audio will still maintain their ability to utilize their Hands-Free Voice Control functionality and track controls.

The person who wants to join will press the button on their LEFT earbud for 3 seconds, and they can be in either a connected or non-connected state. A voice prompt will notify the user they are now “Joining Audio”. Once connected, the user joining will not have voice control or track control functionality.

Once the share is complete, audio will begin to stream automatically and each user will have the ability to adjust their volume independently through their earbuds.

Either party can disconnect from the Audio Share by placing their earbuds into the case and closing the lid, powering the earbud off manually, or repeating the 3-second hold you used to share or join the stream.

To continue the Share session if either user is disconnected, both parties will need to start over.

Share Audio:

  • Press and hold 3s on the right earbud to “Share” your audio (must be connected)
  • Press and hold 3s on the left earbud to “Join” audio (can be connected or in a disconnected state)

SKULL-iQ & THE SKULLCANDY APP

To unlock all of the incredible Skull-iQ features, scan the QR code on the front of your packaging or in your Quick Start Guide to quickly download the Skull-iQ App.

Once you have paired your earbuds to your device, open the Skull-iQ App and you will automatically link. You now can enable hands-free voice control, customize your control settings, access user guides, and update new features when they become available.

It is very important to be sure you’ve updated your earbuds to the latest firmware release to ensure the best performance and user experience. You will be notified when an update is available, but please don’t forget to take this time and improve your product with the most up-to-date upgrades and features.

HANDS-FREE VOICE CONTROL

For both Android and iOS, the Skull-iQ App is required.

Once your earbuds have linked with the Skull-iQ App, Hands-Free Voice Control will be enabled each time you power on and pair your device. You may also disable this feature in the app at any time if desired.

Your voice controls will continue to work if the app is in the background, even when the phone is locked. Generally, iOS users will simply need to link to the app once and leave running in the background, and Android users can link to the app and utilize voice controls with or without the app running in the background.

A few special cases exist as follows:

For iOS users, voice controls will work as long as the app is running in the background (This is also how Tile, Google Assistant, and Alexa work in iOS).  Once installed, if the app is closed while the earphones are connected, voice controls will stop working.  However, when the user disconnects, and then reconnects the earphones again (e.g., places them in the charging case and removes them later), the app will automatically launch when the earphones reconnect, and voice controls will work as expected.  Only in the case where the app crashes or the user quits the app while the earphones are connected, will voice controls stop working until the user manually relaunches the app, or disconnects/reconnects the earphone.

For Android users, once the app has been installed, and has run at least once, voice controls will continue to work even if the user closes the app.  If the phone is restarted, the user will need to restart the app to re-enable voice controls.

Wake Word and Voice Commands:

Once you’ve turned this feature on in the Skull-iQ App, these simple commands will activate your hands-free voice control.

The user will first say “Hey Skullcandy”, and you will receive an audible tone to indicate Skull-iQ system is listening, and you will quickly follow this up with one of the following commands. Once the earbuds recognize the command, you will also receive an audible tone to confirm this action. (You will be able to say the wake word + command together normally, or with a slight pause between them.)

Commands:

  • Play (Music Streaming)
  • Pause (Music Streaming)
  • Volume Up (Music Streaming)
  • Volume Down (Music Streaming)
  • Next (Media Control)
  • Previous (Media Control)
  • Stay Aware On
  • Stay Aware Off
  • Spotify
  • Assistant

In addition, when there is an incoming phone call, there is no need to use the “Hey Skullcandy” wake words, you can simply say, “Accept” or “Reject”.

Incoming Call:

  • Accept (doesn’t require Wake Word)
  • Reject (doesn’t require Wake Word)

ACTIVATE YOUR ASSISTANT HANDS-FREE:

“Hey Skullcandy, Assistant”

This is a massive feature benefit, allowing the user to activate their default device assistant (for example Siri, Google, Alexa) to send a text, make a call, set a timer, or confirm the speed of light, anything at all, hands-free while your phone is in your pocket or backpack.

Where does voice control work best and what factors can impact Voice control:

Voice control is an amazing, freeing experience. Imagine plopping your phone in your backpack, and then controlling your music and answering a call, all without ever taking your hands off the handlebars of your bike. Like any technology, it also has some limitations and will work better under some conditions than others. ​

For example, voice control will generally work very well in quieter situations like your home office, or when running, hiking, or riding on quieter streets or trails. Even the noise of a passing car or average office noise is not usually a problem. Some testers have reported that even while riding a bike on the busy streets of Munich, voice controls worked surprisingly well. Your mileage may vary. ​

Generally speaking, walking or running along very noisy streets, or sitting in a bustling café will reduce the ability of the earphone to “hear” you when you speak, and may reduce the accuracy of voice commands. You may also experience a higher incidence of “false triggers” where the voice control triggers even though you didn’t speak the wake words “Hey Skullcandy”.​

In noisier environments, you may have to speak the voice commands more loudly or may need to repeat them. If your environment becomes loud enough, voice controls may not respond regardless of how loudly you speak. How loud is too loud? Likely, if you have a hard time hearing someone else speak to you, it’s probably going to be hard for the earphones to hear you, too.

Wind also creates intense aerodynamic turbulence that can overload the microphones needed to pick up your voice. Voice Control will generally work in winds up to 8MPH, but you may have to raise your voice. Voice control success in winds higher than 8MPH will depend on wind direction and other factors, like which earphone is being used as the microphone for voice control.

For example, running an 8-minute mile in calm conditions produces the equivalent of an 8MPH headwind. Racing downhill on a mountain bike is much higher, and voice control may not work in these cases, or when you are in a windy situation.

CUSTOM BUTTON ACTIONS

You can personalize your earbuds through the Skull-iQ App by customizing your UI controls

Some default actions and other unassigned button actions can be re-configured through the Skullcandy app.

Custom button actions for both the LEFT and RIGHT earbuds:

Here are the customizable button actions that you can configure to your preferred control settings.

  • Double press (2x)
  • Triple press (3x)
  • Hold (1s)

Custom button functions during idle or streaming media:

Here are the controls that you can assign to the above button actions.

  • Take Photo
  • Next Track
  • Previous Track
  • Volume Up
  • Volume Down
  • Activate Phone Voice Assistant
  • Spotify Tap™
  • Stay Aware Mode ON/OFF

TAKE PHOTO

The Take Photo feature allows your earbud to act as a wireless remote for your device’s camera!

All you need to do is set one of the custom button actions to the Take Photo feature in the Skull-iQ App and then open the camera on your device. As long as your earbuds are paired with the device and linked to the Skull-iQ App, your custom button action will take a picture on command.

For best results, use the earbud as the remote in your hand, or leave them in and set the timer in your camera’s settings so there is a few seconds delay before snapping the photo, this way you’re not caught with your hand on your earbud in every photo.

STAY AWARE MODE

On/Off switch in the app (default OFF)

GRIND FUEL Stay Aware Mode can be activated through hands-free voice control, in the Skull-iQ App, and as a customizable button action.

Stay-Aware Mode makes it easier to hear what’s going on around you without having to remove an earbud, so you can enjoy your music in stereo and stay in touch with your surroundings.

PRESET EQ + CUSTOM 5 BAND EQ

To help you get the best sound quality from your content, GRIND FUEL features 3 preset EQ modes + 1 CUSTOMIZABLE 5 BAND EQ (Custom EQ Mode):

  • Music Mode
  • Podcast Mode
  • Movie Mode
  • Custom EQ Mode

To switch between EQ Modes, head into the Skull-iQ App and select your preferred audio setting.

Your default EQ setting is “Music Mode”, which is great for general listening.

Podcast Mode removes most of the bass response and is great for podcasts or audiobooks.

Movie Mode boosts dialog and detail in your audio, creating an enhanced immersive experience.

You also can create your own Custom EQ Mode. This is a 5 band Equalizer that allows you to adjust the low, mid-low, mid, mid-high, and high sound frequencies to your preferred levels, personalizing your sound experience.

GRIND FUEL PERSONAL SOUND

Personal Sound technology allows you to tune the earbuds to your unique hearing.

It’s like having prescription glasses for your ears — it will allow you to hear your music EXACTLY as it was meant to sound.

In the Skull-iQ App, open GRIND FUEL and toggle on Personal Sound. Now, follow the prompts to begin the audio test.

This audio/hearing test will require a simple button press and hold while you hear a tone in the background. You will complete this test for both ears to fully customize your sound profile.

After you’ve completed the test, the app will create a personal sound profile that’s matched perfectly to your hearing. There will also be a slider tool in the APP that allows you to increase or decrease the amount of tuning in your sound profile.

Many people report being able to hear sounds and layers in their music that they’ve never heard before.

You can turn your Personal Sound Profile on or off in the app at any time, but you can only create 1 Personal Sound Profile at a time on each paired device. Please note that you can also delete your profile and retake the test to create a new profile.

ADD NEW FEATURES AND UPGRADES AS THEY BECOME AVAILABLE THROUGH THE Skull-iQ APP

Instead of buying new earbuds for the latest features, your Skull-iQ-enabled earbuds allow you to add new features as they’re developed.

This means that over time, we’ll add more hands-free voice controls, including the ability for deeper user customization and other new features — all delivered through firmware updates via the Skull-iQ App.

It is important to always be sure your earbuds are updated to the latest firmware release to ensure the best performance and user experience, so please don’t forget to take this time to improve your product with the most up-to-date upgrades and features.

HOW IT WORKS:

Occasionally, you’ll receive notifications through the Skull-iQ App that your product is ready for a firmware update.

FOTA (Firmware Over-The-Air) updates will be prompted on the home page of your linked product, and you will simply press the “Update” button for more detailed information before getting started with your upgrade. 

After reviewing the firmware improvements and or feature upgrades, swipe forward and get ready to begin your update. This will take about 5-10 minutes, and please note that both earbuds will need to have a battery capacity of over 25% to begin. Once you’ve pressed the “Start the update” button, be sure to maintain a constant WIFI or cellular service, keep your earbuds and device powered on and close together to maintain the Bluetooth connection, and do not exit the Skull-iQ App (this can update in the background, but the app must continue running).

Once the update process has finished, you will be notified that your firmware update has been completed.

CHARGING:

When fully charged, there will be up to 9+ hours of playtime in the buds and you will get 31+ hours in the charging case, reaching up to 40+ total hours of playtime.

EARBUDS:

  • Place them in the case and CLOSE THE LID to begin charging.
  • When you open the charging case, the LEDs on both earbuds will indicate if they are fully charged (solid BLUE) or if they are still charging (RED).
  • 10 minutes of charging will provide 2+ hours of playtime.
    • You will hear the “Battery Low” voice prompt with about 45 minutes of playtime remaining (about 15% charge), and again with about 20 minutes (8%) of playtime left.
  • You can also check their battery life on the paired device on your shortcuts screen, or in the Skull-iQ App (earbud battery life shown individually) when they’re connected to your device.

CASE:

  • Plug in the USB-C Rapid Charge cable and connect to a computer, wall charger, power bank, or 12-volt adapter in a car. The white LED indicator above the USB-C port will pulse WHITE while charging and will remain ON when the case has become fully charged.
  • A 10-minute charge of the charging case via your USB-C cable will provide 4+ hours of battery playtime.
  • To check how much battery life is left, open the case lid and the case LEDs will turn on. Each LED represents 25% charge capacity, and while charging they will go from pulsing until all four LEDs are solid, which means your case is 100% charged.

GRIND FUEL

You may also charge your GRIND FUEL wirelessly by setting the charging case on a wireless charging pad or wireless charging power bank (such as the Skullcandy Stash Fuel).

SOLO MODE and a FIX:

To use Solo Mode and you’ve previously paired to your earbuds, simply remove either earbud from the charging case and this solo earbud will function with both phone calls and music, as well as your hands-free voice controls. Please note the Stay Aware Mode feature will not work in Solo Mode*.

If you are initially pairing only one earbud, simply follow the same pairing steps above normally and you’re good to go.

To use both earbuds again, simply remove the other bud from the case at any time, you will hear the power on “pling” tone, and your audio begins to seamlessly stream back into Stereo mode.

However, if you’re having any challenges using either earbud solo, you may follow the above simple steps to troubleshoot and ensure ease of use when pairing and switching between Solo and Stereo Modes.

FIND YOUR LOST EARBUDS WITH THE TILE™ APP

To make sure you never lose your earbuds, we’ve built Tile technology into GRIND FUEL.

The Tile® Finding Technology is easy to set up and will allow you to locate either one of your earbuds if you’ve misplaced them or if they’re ever taken.

When searching for missing earbuds, you can also use the Tile™ App to sound a tone from your buds to help you locate them. You can sound a tone from one earbud or both.

First, you’ll need to download the Tile™ App for this feature to work. Once you’ve downloaded the Tile app follow the on-screen instructions to connect each earbud individually so they are both trackable.

FIT:

GRIND FUEL fits comfortably and securely in your ear. Here’s how to get the best fit.

First, place the bud in your ear at an angle, then rotate minimally to the front or back to secure it in place. Your earbuds should feel comfortable and stable.

For optimal acoustic performance, you also want to be sure your ear gel creates a nice seal just inside your canal.

GRIND FUEL comes with 3 sizes of ear gels to help you find the best fit. Try each size of the provided ear gels to see which fit works best for you.

Having Trouble? Let us help!

No Audio in one ear?

Let’s re-sync your earbuds by first placing both of them into the charging case and closing the lid for 2 seconds to ensure they fully power OFF. Then simply remove both earbuds together, if the stereo audio stream hasn’t been fixed, please follow the two options below.

Step One:

  • On your device, open the Bluetooth settings and turn Bluetooth Off.
  • Remove both earbuds from the charging case and ensure they are both powered ON.
  • Press the button on both earbuds three (3x) times simultaneously. The LED will go through a series of pulses as they re-sync. Five quick (5x) blue flashes will indicate a successful sync.
  • On your device, open the Bluetooth setting back up, turn this ON, and select your previously paired “GRIND FUEL”.
  • LEDs in both earbuds will blink blue three (3x) times and a voice prompt will indicate a successful connection.

If this step fails, or you are having pairing issues, please proceed to Step Two

PAIRING ISSUES? Reset your earbuds with the following steps.

Step Two:

  • Remove the GRIND FUEL from your Bluetooth Paired Device list settings, and then turn the Bluetooth OFF.
  • Remove BOTH earbuds from the case, a Tone and Voice Prompt will indicate your earbuds are Powered On.
  • Press and hold ONLY the RIGHT earbud button for three (3) seconds.
  • A tone will indicate a successful reset and the RIGHT earbud will flash purple 3 times, a voice prompt will say “Ready to Pair”, and both earbuds will pulse red/blue/
  • On your device open your Bluetooth setting and turn Bluetooth ON. In the available devices select GRIND FUEL and accept the “Pair” or “OK” prompt that appears on your screen. When pairing is complete, a voice prompt will say “connected.

BUDS NOT CHARGING IN THE CASE/CASE LID NOT CLOSING PROPERLY?

Issue: Not seeing the LED indicator on the buds when you’ve placed your GRIND FUEL back in the charging case.

Solution:

  • Check to see if any debris is blocking the charging pins at the bottom of the case, or on the bud.
  • Check to see if the removable in-ear gels have been twisted or are falling off. This could be keeping the buds from sitting correctly in the case. If you’re having a hard time closing the lid completely, it is likely because the earbuds are not set correctly or the gels are interfering.
  • Check the battery level fuel gauge on the charging case to ensure the case is holding a charge.

  • Nope, this feature is set up in your default UI settings as a 1s press on your LEFT earbud. Although, you may also customize this button action within the Skullcandy APP.

Do I need to have the Spotify App downloaded on my phone for this feature to work?

  • Yes, you will need to have the Spotify app downloaded on your phone as well as an active registered account.

Share Audio

Do I need to be linked with the Skull-iQ App for this feature to work?

  • Nope, this feature is also set up in your default UI settings, but both users will need to have SKULLiQ-enabled earbuds. (Currently supported programs are GRIND / GRIND FUEL / PUSH ACTIVE, these products will be available in 2021)

How do I share my Audio with another SKULLiQ user?

  • To start a session, the person sharing their audio will need to be connected to a device and can be streaming or in an idle state, they will press the button on their RIGHT earbud for 3s to initiate, and will hear the voice prompt “Sharing Audio”.
  • The person joining the session will power their buds ON and can either be in a connected or non-connected state, they will press the button on their LEFT earbud for 3s to initiate, and will hear the voice prompt “Joining Audio”.
  • Please be patient as it sometimes takes about 5 seconds to begin the Audio Share streaming for the user joining the session.

Can I customize the action buttons for the Share Audio feature?

  • No, this is a locked UI action and you cannot change this default button function.

Do both users still have full media controls and voice control?

  • No, only the user sharing audio will maintain their hands-free voice control, track control, and play/pause capability.
  • Both users will still have independent volume controls and the ability to end the Audio Share session by powering off the buds or repeating the same button action sequence they used to begin their session.

Hands-Free Voice Control

Will voice control work right out of the box?

  • No, the user will need to first download the Skullcandy App and link their Skull-iQ-enabled product to the APP to enable hands-free voice control.
  • The user will be notified with a voice prompt, “Voice Control ON” when enabled. They will also be able to turn ON and OFF in the APP as desired.

Do I need to always keep the Skullcandy App open for Voice Control to function?

  • iOS users will only need to keep the app running in the background to maintain voice control functionality.
  • Android users will be able to link to the app and close the app while still maintaining hands-free voice controls.
  • The user will always be notified if their voice controls are ON or OFF via a voice prompt during power-up and when enabling and disabling in app.

Sometimes I hear the tone that indicates voice controls were “listening”, is there something wrong with my product?

  • No, this is normal, but should not be a common occurrence. This is called a “false trigger” and it is when your earbuds may hear a phrase that sounds like, “Hey Skullcandy”. Although it should not impact your everyday use, it may occasionally happen.

Do I need to speak loudly for this feature to work?

  • No, you should be able to speak normally in most scenarios for the mics to hear your commands. Though situation-dependent, you might need to speak a little bit louder in noisy or windy environments.

Will my voice controls always work perfectly?

  • Not always, some limitations will interfere with the hands-free voice control performance. Mainly loud surrounding noise or high winds can impede the microphone from being able to always hear your commands.

Can I answer phone calls hands-free?

  • Yes! Simply say “accept” and you will be able to answer your call hands-free.
  • You can also say “reject” if you are not able to take your call at that moment.
  • No “wake word” is needed for this feature, so you don’t have to say “Hey Skullcandy” before these commands.

Will my accent impact voice control performance?

  • It should not. We have tested these controls with accents from around the world with great success.

If I switch devices from my phone that has linked to the app, to a device that does not have the Skull-iQ App, does my hands-free voice control still work?

  • No, you will revert to the default UI controls and will not have the Skull-iQ features such as hands-free voice control.

Custom Button Actions & Functions

How easy is it to customize my earbud controls?

  • This is done very easily through the Skull-iQ App, where you customize both your LEFT and RIGHT earbuds independently.

Can I customize all earbud functions?

  • No, some button actions such as play/pause, answer/hang up call, and Share Audio cannot be modified.

Will my custom button actions/functions be saved even if I power OFF/restart my device?

  • Yes, once your controls are customized in the Skullcandy APP they will be saved until you make changes.

If I get a new phone and need to re-download the app, will my controls be saved?

  • No, you will need to re-link to the app and customize your button actions again.

If I switch devices from my phone that has linked to the app, to a device that does not have the Skull-iQ App, do my customized button functions still work?

  • No, you will revert to the default UI controls and will not have the Skull-iQ features such as hands-free voice control or custom button actions.

Take Photo

I don’t understand, what the h*ck is this?

  • This feature will allow your earbud to become a wireless remote for your phone’s camera. Simply set up the custom button action in the Skull-iQ App, open your camera app on your phone, and press the button action to activate the camera shutter wirelessly! That means you can take still photos or start/end a video with a simple press of your earbuds button.
  • Great for group shots and selfies without having to set your phone and race against the timer.
  • Leave your earbuds in your ears and set the timer on your phone so you can press them and not get caught with your hands in your ears, or simply hold the earbud in your hand to snap away more subtly.

Do I need to set up this function as a custom button action?

  • Yes, this is not a default UI setting, so you will need the Skull-iQ App and a Skull-iQ-enabled product to use the Take Photo feature.

Do I need a special camera app for this to work?

  • No, this feature will work directly with your phone's existing camera and will utilize the existing shutter settings.

Personal Sound – GRIND FUEL
