Sony Wh-Ch700n
ANC, 35 h, Cable
Hello all, I am trying to connect the headphones (Sony WH-CH700N) via Bluetooth to my PC (Windows 10 Pro). They are recognised and connected, but as "another device" and not as headphones. Windows 10 does not output sound via an "additional device", the headphones remain mute. Connection with Android mobile phone and tablet works, another Bluetooth headset could be connected and used with the PC without any problems. "Factory reset" on the headphones did nothing, nor did reinstalling all Bluetooth drivers on the PC. Windows 10 Pro, version 20H2, build 19042.746. Bluetooth dongle from TP-Link, BT version 4.0. According to the "Sony Headphone App", the firmware of the headphones is up to date. Does anyone know the problem and the solution? Thank you in advance for your support.
