Our Verdict
Focal Bathys Wireless
Sennheiser HDB 630
The Sennheiser HDB 630 and Focal Bathys Wireless are both high-end Bluetooth headphones that target audiophiles in search of a portable pair of cans. In general, the Sennheiser are the better pair, with a much longer battery life, superior noise isolation, and a more controlled sound. That said, the Sennheiser have poor frequency response consistency, so if you wear glasses or often have difficulty finding a pair of headphones that fit just right, the Focal are the better bet.
