Bluetooth headphones: are there any?

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.

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... 

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.
