Frequently Asked Questions

My Bose headphones are connected and showing audio playing but I hear nothing — why?

This is usually an audio routing issue. The phone thinks it is sending audio to Bose but the audio is actually going to a different output. Disconnect and reconnect Bluetooth to force the routing reset.

Bose QuietComfort has sound only in the left ear — how do I fix it?

Single-ear audio can be caused by a damaged cable connection, a failed driver, or a balance setting set to one side. Check the audio balance in your device accessibility settings.

Does Bose noise cancelling affect sound quality?

At maximum NC, some users perceive a slight change in bass response. This is normal. Try reducing NC level in the Bose Music app if audio sounds unnatural.
