Just purchased the QC Earbuds. For some reason, volume control affects balance dramatically. Low volume swings balance of audio to the left. High volume to the right. Only at the middle volume setting does the audio output seem centered. This has to be a bug. Using on an iPhone. Happens with both phone and app audio control.
Thank you for posting and welcome to the Bose Community! Sorry to hear that you have been experiencing audio balance issues with your earbuds.
Let's start with performing a reset on the earbuds by following these steps here.
We look forward to hearing back from you with the result of this!

I think this is the same as https://community.bose.com/t5/In-Ear-Headphones/Bose-QC-Unequal-Volume-Increase-between-left-right-e...
Good news is there is a "solution" to fix it, but it can happen again (for me, it happened twice).
I really think something should be done, since it seems to be widespread.

Today I have experienced this issue for the 3rd time since I bought the earbuds, two months ago, on February the 18th 2021.
The earbuds are amazing, but this issue is a bit annoying, also to mention that prior to appearing this issue, the noise reduction levels on one side seem to not follow the other on transparency mode.
The firmware version that they had the last 2 times it happened is:
I have successfully reset the earbuds (which seems to temporally solve the problem) by holding the case button for around 30 seconds, as stated here:
If any further info is needed in order to help solve this bug, I would gladly provide it

I have experienced the issue as well, but placing the earbuds in the charging case for around 5 minutes tends to fix it. Basically the earbuds need to drop to their lowest power state and then turn back on.
Hopefully they will release the firmware update to fix it permanently.
