I got the Bower Wilkins PX8 about 6 months ago and love it. I originally went with the PX8 over the Focal Bathys due to it being $100 cheaper than the Focal Bathys, more compact form factor, and the reportedly better noise cancellation. MDs have widely-reported problems with their Bluetooth connectivity.

However, I am Focal-curious. Some reviews have the FB noticeably better sound. And, right now, B&H is offering the FB at a $150 discount, dropping it below the BW.
