To adjust headphones settings in Suunto app:
Suunto Sonic headphones are bone conduction headphones with open-ear style, allowing you to listen to audio and still hear your surroundings during exercises.
For the proper experience, put the headphones to the back of your head, with the hooks on your ears so that the transducers rest in front of your ears. Keep the back of the headphones parallel to the ground.
Whether you are training in the gym or you are out on rugged paths, the headphones stay stable on your head. Thanks to their light weight and the open-ear style, the headphones are comfortable to use for several hours. You can wear Suunto Sonic together with a bike helmet or a hat and even under a beanie.
You can choose from different sound modes when wearing your headphones. Your Suunto Sonic offers a normal sound mode for everyday use and light exercises and another sound mode for outdoor trainings and noisy conditions. In the outdoor sound mode, the volume is higher. Select the mode that provides the best experience in your given situation.
Noise may occur at high volume levels.
While listening to audio, you can switch sound mode by keeping the multifunction button and the button pressed simultaneously for 3 seconds. If you have Suunto app installed on your phone, you can also change sound mode in the app.
Prolonged use of headphones at high volume levels can lead to hearing damage and sound distortion.
Wearing headphones may impact your ability to hear your surroundings. Use your headphones responsibly and prioritize safety.
If you have a voice feedback capable Suunto watch, you can get voice feedback with valuable information during your exercise. The feedback can help you to keep track of your progress and give you useful indicators, depending on what feedback options you have selected. The voice feedback comes from your phone so your watch and your headphones must be paired with Suunto app.
To activate voice feedback on your watch before an exercise:
Your phone will now bring you various voice feedback during your exercise, depending on which voice feedback you have activated.
To activate voice feedback on your watch during an exercise:
You can connect your Suunto Sonic to two Bluetooth devices at the same time. With the help of the dual device connection function, you can easily switch to your phone and answer a call while listening to music from your computer.
Follow these steps to pair your headphones with two devices:
You can check the list of the connected devices in Suunto app.
When you use Suunto Sonic with two paired devices at the same time, the headphones determine their own priority based on the order of the played content and the tasks. Normally, the first played audio takes precedence over the second, and phone calls take precedence over audio playback. However, the actual operation of different brands and models of the compatible devices may vary.
Low latency mode reduces the delay of the sound when you are listening to audio or watching video wearing Suunto Sonic.
To use low latency mode, the compatible device needs to support the APTX Adaptive Bluetooth audio. After pairing the headphones with the compatible device, switch the audio format to APTX Adaptive on the Bluetooth settings page of the paired device. On some devices, you need to turn on low latency mode separately.
The low latency effect might vary depending on factors such as the model and system version of the compatible device, the app you use for playing the audio and playback content type.
You can check device info, for example, the software version of your headphones in Suunto app.
Software updates add important improvements to your headphones. For updating the software, the headphones must be connected to Suunto app. Internet connection is required for downloading the update package. For installing the update package, the battery level of the headphones must be at least 20%.
When an update is available, a popup window offers you the update option after opening Suunto app. Keep the headphones connected to your mobile phone during the update process. When the update is complete, the headphones will restart.
You can check the software version of your headphones under the device settings in Suunto app.
In case you want to delete all your settings from Suunto Sonic, you can reset the product. While Suunto Sonic is charging, keep the multifunction button pressed for 5 seconds. When the LED light alternately blinks red and white once and the headphones play a sound, the reset is successful.
After the reset, the Bluetooth pairing records are deleted from the headphones. When you want to use the headphones again, you have to start the pairing process from the beginning. See Pairing.
Handle the unit with care, do not knock or drop it. Do not store the headphones below heavy items as the headphones may get deformed.
When the surface of the product is dirty, wipe it clean with a soft dry cloth. Pay special attention to the microphones, buttons, and charger pins.
Under normal circumstances, the headphones do not require servicing.
Use only original Suunto accessories. Damage caused by non-original accessories is not covered by warranty.
The battery performance on a single charge depends on how you use your headphones and in what conditions. Low temperatures, for example, reduce the duration of a single charge. In general, the capacity of rechargeable batteries decreases over time.
The headphones are fully charged in one hour, and you can listen to up to 10 hours of music with one charge.
When the battery level is less than 5%, the headphones play a low battery alarm tone every 5 minutes, and the red LED light is blinking.
To check the battery status of your headphones, connect the product to Suunto app. You can see the battery status on the headphones' page in the app.
For charging your headphones, use the supplied USB cable.
The USB charging cable is included in the product package. For charging the headphones with the cable, connect the magnetic end of the cable to the charging port of the headphones. If the headphones are switched on, they will automatically switch off when the charging starts. While the headphones are charging, the red LED light is on. When the battery is fully charged, the LED light turns white for a minute, then it turns off.
Please dispose of the device in accordance with local regulations for electronic waste. Do not throw it in the garbage. If you wish, you may return the device to your nearest Suunto dealer.
