I have the XM3 and wouldn't full-time endorse them. Generally, I don't like the bulk or hair-interfering qualities of headphones. Its features are more or less a gimmick. And apparent build quality isn't the best. Finally, noise cancellation is overrated. Airplane is mostly pink noise that my subconscious buries.

But worst of all, their microphone quality is absolutely horrendous.

I don't hate it besides the microphone thing, I think it's merely okay.

If I had to buy again I'd consider the Windows Surface headphones - appears to be built better, and the dual control knobs is a superior implementation. Also the B&W PX.

My only reservation about the fully wireless earphones is imagining myself losing them so easily. Would prefer a corded-wireless system where the 2 buds are wired together.
