RAIL USER GUIDE, TROUBLESHOOTING & FAQS
RAIL ANC IS SUPPORTED BY THE SKULL-IQ APP
INITIAL SET UP & PAIRING HELP:
QUICK START VERSION: (EASIEST 1ST TIME PAIRING)
PAIR TO A NEW DEVICE: (AFTER 1ST TIME PAIRING, WHILE EARBUDS ARE NON-CONNECTED)
MULTIPOINT PAIRING: PAIR TO A 2ND NEW DEVICE (AFTER 1ST TIME PAIRING, WHILE EARBUDS ARE POWERED ON AND CONNECTED)
This feature makes it possible to pair your earbuds with two devices at once. The connection is managed automatically — you won’t need to do anything after pairing the second device.
For example — while watching YouTube videos on your laptop, you can take a call on your phone without the hassle of disconnecting from one device to pair with another.
Now that you’ve paired to multiple devices, each time you power on your earbuds they will automatically sync to the 2 most recently paired devices.

QUICK START DEFAULT USER CONTROLS
Out of the box, Rail ANC’s default on-board 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 tapped the capacitive touch sensor on their earbud, and when tapping 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 sensor response tone will help you quickly learn your way around the controls on your device.
AUTO POWER ON & POWER OFF:
DEFAULT USER INTERFACE CONTROLS:
MANUALLY POWER ON: EITHER EARBUD
MANUALLY POWER OFF: EITHER EARBUD
PLAY/PAUSE: EITHER EARBUD
ANSWER/HANG UP CALL: EITHER EARBUD

SPOTIFY TAP™
We’ve partnered with Spotify to create an instant path to your music through a simple touch sensor press right out of the box.
Once you’ve paired your earbuds to your device, touch and hold either earbud for 1 second, you’ll hear an ascending tone and will have instant playback through your Spotify app.
SPOTIFY TAP™: EITHER EARBUD (SPOTIFY APP REQUIRED)
This starts your playlist back up from where you left off or will queue up music based upon your stellar taste in music.
*Once paired to 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”.
SKULL-IQ SMART FEATURE TECHNOLOGY®
Skull-iQ Smart Feature Technology® will change the way you stream your favorite media. It features Hands-Free Voice Control, and gives you access to new features and upgrades through the Skull-iQ App.
To unlock your earbuds’ Skull-iQ features, scan the QR code in your Quick Start Guide to download the Skull-iQ App.
Once you’ve paired your earbuds to your device, open the Skull-iQ App and it will automatically link.
The app allows you to enable Hands-Free Voice Control in five different languages, customize your button functions, adjust your Stay-Aware Mode intensity, create your own personalize sound profile powered by Mimi®, select preset or custom EQ Modes, take photos with a custom button setting or voice command, access user guides and update new features when they become available.
You also have access to other voice assistants, like Alexa and iHeartRadio. Just enable them in the Skull-iQ App for a direct connection.
You can ask Alexa to add something to your shopping list, or ask iHeart to play your favorite artist or genre - no additional app downloads needed. Just say “Hey iHeart.”
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.
Once you’ve downloaded the app, connect your earbuds and turn voice control ON.
Each time you power ON your earbuds, you will be notified “Voice control ON.” Now you’re ready to issue “Hey, Skullcandy” commands.
You can also enable other voice assistants in the app, such as Amazon’s Alexa. Once turned on, just say “Alexa” and then follow up with your request, such as “what’s the weather” or “track my order.”
Voice controls will work as long as the app is running in the background, even if the phone is locked. So, if you find your voice commands aren’t working, try re-opening the app to reconnect.
Voice control is an amazingly freeing experience. Imagine dropping your phone into your bag, and then controlling your music and answering a call, or activating your device’s assistant to send a message, all without ever touching your phone.
Hands-Free Voice Control will generally work very well in quieter situations like your home office, or when running, hiking or riding on quieter streets.
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 charge 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 voice control ON in the Skull-iQ App, you’re ready to stow your phone in your pocket or backpack while still having full Hands-Free Voice Control.
Your earbuds respond to commands in one of five different languages — English, Spanish, French, German or Chinese. You can choose the language you’d like to use in the Skull-iQ App.
First, say “HEY SKULLCANDY”. You’ll hear a tone which lets you know that Skull-iQ is listening, and then quickly follow this up with one of the commands listed below:
TO ACCEPT OR REJECT A CALL, SIMPLY SAY “ACCEPT” OR “REJECT” WHEN RINGING. NO WAKE WORD NECESSARY.
Pro tip: you can adjust your phone settings to announce who’s calling you, so you can accept or reject without ever checking your phone.
All voice commands are available for quick reference in the app. You will also find them in the printed Quick Start Guide that came in your packaging.
ACTIVATE YOUR ASSISTANT HANDS-FREE:
“HEY SKULLCANDY, ASSISTANT”
This is a massive feature benefit, allowing you to activate your device’s native 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 bag.
You also have access to other voice assistants, like Alexa and iHeartRadio. Just enable them in the Skull-iQ App for a direct connection.
You can ask Alexa to add something to your shopping list, or ask iHeart to play your favorite artist or genre - no additional app downloads needed. Just say “Hey iHeart.”
WHERE DOES VOICE CONTROL WORK BEST AND WHAT FACTORS THAT 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 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 earphone 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 earbud 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.
SKULL-IQ APP
There are many additional features in the Skull-iQ App:
You can use the app to:
ADJUSTABLE STAY-AWARE MODE
Adjustable 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 audio and stay in touch with your surroundings.
A slider in the Skullcandy App allows you to set Stay-Aware Mode to your preferred level.
Turn Stay-Aware Mode down to focus on what you’re listening to, or turn it up to amplify the sounds around you.
This is especially nice at the airport, when you want to hear announcements or at the gym, when you want to keep track of what’s going on around you.
To turn it on, just say “Hey Skullcandy, Stay-Aware ON.”
And to turn it off — you guessed it — just say “Hey Skullcandy, Stay-Aware OFF.”
Adjustable Stay-Aware Mode can be activated through hands-free voice control, and in the Skull-iQ App you can adjust the intensity and set a custom button function to turn it on and off via your on-bud touch sensor UI.
PERSONAL SOUND BY MIMI®
Everyone’s hearing is different — that’s why Rail ANC features Personal Sound by Mimi®. By taking a short hearing test in the Skull-iQ App, you’ll create a personalized sound profile which the app uses to tune your headphones to your unique hearing. You’ll pick up on details in your music that you never even knew were there.
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 app, locate your earbuds and toggle Personal Sound ON. Follow the prompts to take the quick audio test.
You’ll be asked whether you hear a sound. Simply answer yes or no and complete the test for both ears.
After you’ve completed the test, the app will create a personal sound profile that’s matched perfectly to your unique hearing.
You can turn your Personal Sound Profile ON/OFF in the app, and don’t worry if you share your earbuds, you can also create sound profiles for different users and switch between them anytime.
CLEAR VOICE SMART MIC
Rail ANC is equipped with Clear Voice Smart Mic which utilizes an advance microphone and artificial intelligence software to isolate the speaker’s voice and reduce background noise. This is especially effective at eliminating discontinuous noise — the kind of background chatter you’d find in a crowded coffee shop or airport.
This means that whoever you’re speaking with, whether you’re on on the move or sitting at your computer, will be able to clearly hear your voice in nearly any situation.
CUSTOMIZE BUTTON FUNCTIONS
You can personalize your headphones through the Skull-iQ App by customizing your controls.
SOME DEFAULT SETTINGS AND OTHER UN-ASSIGNED UI ACTIONS CAN BE RE-CONFIGURED THROUGH THE SKULL-IQ APP TO ALLOW YOU TO MAKE YOUR EARBUD CONTROLS MORE INTUITIVE TO YOU.
THESE ARE THE CUSTOM BUTTON FUNCTIONS THAT YOU CAN CONFIGURE TO YOUR PREFERRED CONTROL SETTINGS FOR BOTH YOUR RIGHT AND LEFT EARBUDS:
THESE FUNCTION CONTROLS CAN BE CUSTOMIZED IN THE SKULL-IQ APP:
PRESET EQ + CUSTOM 5 BAND EQ
To help you get the best sound quality from your content, Rail ANC features 3 preset EQ modes + 1 Custom EQ Mode:
TO SWITCH BETWEEN EQ MODES, OPEN THE SKULL-IQ APP AND SELECT YOUR PREFERRED AUDIO SETTING. A VOICE PROMPT WILL NOTIFY YOU EACH TIME YOUR EQ MODE CHANGES.
Your default EQ setting is “Music Mode”, which is great for general listening.
Bass Boost Mode increases the low frequencies for a bass-heavy audio experience.
Podcast Mode removes most of the bass response and is great for podcasts or audio books.
You also have the ability to 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.
TAKE PHOTO
The Take Photo feature allows your earbuds to act as a wireless remote for your device’s camera.
Just set one of the custom button settings to the Take Photo feature in the Skull-iQ App, and then open the camera on your device.
As long as your earbuds are linked with the device and app, your custom button setting will take a picture or start and stop recording on command.
Also, if you’re connected to the Skull-iQ App and have voice controls turned on, just say, “Hey Skullcandy, take photo” to trigger your device’s camera.
For best results, use the earbud as the remote in your hand or your voice and set the timer in your camera’s settings so there are a few seconds delay before snapping the photo.
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 totally new features — all delivered through firmware updates via the Skull-iQ App.
It is very important to always be sure your earbuds are updated to the latest firmware release to ensure the best performance and user experience, so 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 your headphone will need to have a battery capacity 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 headphone 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 was successfully completed.
PLAYTIME AND CHARGING:
RAIL ANC IS LOADED WITH BATTERY LIFE. IT HOLDS UP TO 10 HOURS OF PLAY ON A SINGLE CHARGE WITH ANC OFF AND 7 HOURS WITH ANC ON. YOUR CHARGING CASE HOLDS AN ADDITIONAL 28 HOURS OF PLAY TIME WITH ANC OFF AND 20 WITH ANC ON, FOR A TOTAL OF 38 HOURS OF LISTENING TIME WITH ANC OFF AND 27 HOURS WITH ANC ON.
To charge your earbuds, place them in the charging case and the earbuds’ LEDs will turn solid red to indicate they are now charging. You can close the case lid at any time.
When you open the case, the earbud LEDs will be red if they are still charging, and blue when fully charged.
Every time you remove your earbuds from the case and put them in your ears, the Battery Report will tell you how much battery life you have as a percentage. You can also check your earbud battery life in the Skull-iQ App or from your paired device.
When your battery has about 45 minutes of play time remaining (about 15% charge), and again with about 20 minutes (8%) of play time left, a voice prompt will notify you “battery low.”
To check case battery life, open the lid or plug in the charging cable. The single LED located next to the USB-C charging port will pulse and indicate the current case battery level.
RED = 0%-25%
YELLOW = 26%-75%
GREEN = 76%-100%
The Rail ANC case can be independently charged whether the earbuds are in it or not.
WITH OUR RAPID CHARGE FEATURE, A 10-MINUTE CHARGE OF THE CHARGING CASE WILL PROVIDE MORE THAN 2 HOURS OF BATTERY PLAY TIME AND IT WILL TAKE JUST UNDER 2 HOURS TO FULL CHARGE THE CASE AND JUST UNDER 1 HOUR TO FULLY CHARGE YOUR BUDS IN THE CASE.
SOLO MODE:
Sometimes you want to be able to hear your music, but still hear what’s going on around you. When you want to do that, you can use just one earbud.
We call this Solo Mode. Both the left and right earbuds can be used in Solo Mode.
To use Solo Mode when you’ve previously paired to your earbuds, simply remove either earbud from the charge case and it will function with both phone calls and music.
If you are initially pairing only one earbud, simply follow the same initial pairing steps above 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 “ping” tone, and your audio will begin to seamlessly stream back into Stereo Mode.
TILE™ FINDING TECHNOLOGY
To make sure you never lose your earbuds, Rail ANC comes with Tile™ finding technology built-in to each earbud.
The Tile tracking feature is easy to set up and will allow you to locate your earbuds if you’re having trouble finding them.
When searching for your missing earbuds, you can also use the Tile app to sound a tone from your earbuds to help you locate them.
First, you’ll need to download the free Tile app and then follow the on-screen instructions to connect the app to your earbuds so they’re easily trackable.
FIT:
Rail ANC fits comfortably and securely in your ear. Here’s how to get the best fit.
First, place the earbud in your ear at an angle, then rotate minimally to the front or back to secure in place. Your earbud should feel comfortable and stable.
For optimal acoustic performance, you also want to be sure your eargel creates a nice seal just inside your ear canal.
Rail ANC comes with 3 sizes of eargels to help you find the best fit. Try each size of the provided eargels to see which fit works best for you.
