Impressive report, however their customer support is terrible for such premium products. Have bought 3 sets of headphones over the last 6 years (2xQC25 and 1xQC35).

Each pair of headphones starts to have audio issues right after the 2 year mark, usually resulting in the total loss of audio in one ear, and their support channels will only advise you to buy a new pair.

Have switched to the competitor - Sony WH-1000XM3. So far so good.

But really disappointed by the quality and longevity of Bose's premium products.

Won't buy again, and for such a serious issue to take this much effort for Bose to allow firmware downgrades just confirms that for me.

I switched from Bose to Sony and haven't looked back. The capacitive controls on the headphones are crap but I never really use them so it's not a big issue for me. Rock solid for music and getting work done.
