Sony MDR-XB50BS Help Manual page 81

Note
If the communication condition is poor, the BLUETOOTH device may react incorrectly to the operation on the headset.
Hint
The headset supports SCMS-T content protection. You can enjoy music, etc., from a device such as a mobile phone or portable TV that supports
SCMS-T content protection.
Depending on the BLUETOOTH device, it may be necessary to adjust the volume or set the audio output setting on the BLUETOOTH device.
Volume during a call and volume during music playback can be adjusted independently. Changing the call volume does not change the volume of
music playback, and vice versa.
