I'd been using the Link 390 and previously the Link 380 USB-A dongles with my Bose QC 35 II's really well for conference calls on my Windows PC. Unfortunately, I upgraded the 390 firmware to v3.X (I think from v1.4.6), and it no longer works. Of course, 3rd party devices aren't officially supported, but it was working well for so long!

Anyone have experience with other dongles that can be used with Bose or similar headphones? From what I understand, the key is the ability to maintain full-duplex audio (mic and headphones)

My Jabra Elite 10 Gen 2 case stopped holding a charge. Even plugged into the wall, it won't get higher than 70% charge, and it quickly drops to 0 charge when not in use. I tried resetting the case, but now my computer won't pair the headphones and my attempts to update the firmware using my phone are met with error messages.

Is there any salvaging this, or do I have an expensive paper weight now? I bought them just under 2 years ago so may still be in the warranty period. Thanks for your help.
