The Bluetooth audio CODEC setting can be managed via the W&H BeHear app (Settings menu, Device option) when the BeHear headset is paired to your smartphone. The recommended setting (and device default) is APTX LL. BeHear supports three different CODECs: • APTX LL provides the best performance with minimal latency. • APTX is similar to APTX LL but the latency is slightly longer. • SBC is the standard Bluetooth CODEC supported by all devices, latency is long and not fixed.
Note: You will need to turn your headset off and back on to apply the modification.
