2. Why the voice lag still here when use this Low latency B03 adapter with my Bluetooth headphones?

To achieve low latency, your receiving device is better also support function of aptX Low Latency. Or, the receiving device might use another codec (e.g. SBC, aptX), resulting in a 70-200ms audio delay which may be noticeable by some users.

In TX mode, take optical cable as the connected audio cable, the Volume + / – on B03 may not work if your device does not support Audio / Video Remote Control Profile.

Change the optical cable to AUX 3.5mm or RCA audio cable, the volume buttons works.
