Bluetooth headphones: are there any?

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

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.

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. 

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!

As I wrote - yes, seen the ratings, and that's how I got to the Momentum 2. So, I thought I'll try not to go to ratings and see where it takes me... 

Rtings has measurements of quite a few. Depending on what phone you have, the quality can be real good. 
 
Bose has a poor reputation, but the QC35 II’s are real good for what they are, as well as the competing Sony MDR1000X M3.

There are many options for really good bluetooth headphones. By the standard of people whose standard is bluetooth.

There's lots and lots. Check out head-fi.org

Need them for travel, so yes, has to be bluetooth

Do you absolutely need them to be Bluetooth or is it really the capability of wireless you need?
