Headphones power on automatically

Hi,

My QC 35 II headphones have developed an issue in the past 3 days.

The Bluetooth LED on the right earcup is constantly showing white, even when you power off the headphones. 

White LED always onWhite LED always on

I consulted the support resources on the Bose site and went through the process of resetting the headphones, but this did not resolve the issue.  I also update the firmware on the headphones to the latest release (4.8.1).  This also didn't resolve the issue.

In conjunction with the whit LED issue, I have noticed that the battery is draining quicker than before.  The battery doesn't get me through a single day now with the same usage patterns (i.e. Microsoft Teams/Zoom calls, listening to podcast and audio books) as before the white LED issue.  It appears as if the headphones are always on, even when powered down.  

 

Open to any assistance or advice anyone has on this issue.

 

Thanks,

-allan

@Allan Gordon(I do not work for Bose)
This is a 'known' hardware issue (for over two years).  Bose stated here in 2019 that it is not fixable by firmware.  This is the only time I am aware of they have commented on it here.  The contacts in the on/off switch are likely slipping.  There is NO workaround.  If this is indeed your problem you have two solutions:
1. Fix it yourself with DIY instructions here and elsewhere

2. Ask Bose for an exchange.  For those out of warranty, they will initially offer the exchange for a price.  Take it or not - your call.  Those who have repeatedly called back and possibly escalated it report here eventually they will get to a representative that will be willing to do a free exchange, 'this one time'.

There is no replacement part.  You can fix it 'as is' with DIY instructions here or elsewhere.  See message #1092.
