16. Does the BTR7 support the headphones' remote control and a microphone? Can I use the microphone in BTR7 in USB DAC mode?
【How to enable】
You could enable the wire function via the FiiO Control app. When wire function is on, you could use the headphones' remote control and a microphone.When wire function is off, you could use the microphone and button control in the BTR7 instead.
The BTR7 supports the CTIA standard for line control as well as line microphone. But the headset with OMTP protocol only supports normal listening.
Microphone is not supported in USB DAC mode. When connecting via Bluetooth connection, you could use the microphone in BTR7.
