Yeah, I noticed recently that my headphones have two modes - sound only, where they sound great, and wireless headset mode, where the sound is awful.

However, it's only awful for music. It's fine for voice, really. I only noticed the two modes when they got stuck in headset mode after I finished a call and I was wondering why the music I put on suddenly sounded bad.

OTOH, this list has made me wonder how much of the delay I hear in video calls is due to bluetooth. Cutting 300ms of delay is much more important than improving already serviceable sound quality.
