If those are the Bose NC700, mine decided after a year to stop charging, and instead smell like melting plastic with smoke coming out of them.

That in itself wouldn't be an _absolute_ terrible thing, except their customer support was _abysmal_.

First of all they suggested I hard-reset the headphones, much to my surprise. When I emphasised that I wouldn't be plugging them in again and repeated the point about smelling melting plastic and smoke coming out, they then asked for pictures before initiating a replacement order process they'd suggested.

I explained that there isn't any visual indicators on the headphones such as melting plastic as I'd noticed it immediately, but they insisted I send them photographs anyway.

On sending them photos as asked (and clarified) they've since gone radio silent for 3 weeks, and ignored any more attempts to get in touch with them.

So yeah... I won't be touching Bose products at all in future.
