Bluetooth headphones: are there any?

If you're using a cell phone as source, and you have an iPhone then make sure the BlueTooth headphones specifically state they are ACC compatible.  Most of the newer models are, but always good to double check.

If you're using a Droid phone, and it's uses aptX, then get headphones that are aptX compatible.  This will provide the best SQ while using BT, IMO.

Good luck!

What are you comparing to?

 I have the Bowers and Wilkins PX and really like them. I would definitely choose over ear instead of on ear. 

I am pretty happy with B&W phones, but I have the older non noise canceling version, so I then added the Sony’s, which are excellent noise cancelers and decent phones to boot.  The B&W are more comfortable.

Plenty on the market. Just don't go with Beats... they are crap! lol
