How do I change the CODEC used by my BeHear headset?
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.
What latency (delay) do your TV transmitters achieve?
The HearLink PLUS Bluetooth transmitter (using the aptX-LL CODEC) achieves low latency of only 40ms, avoiding lip sync issues.
