Suunto Sonic User Guide

Low latency mode

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.
