Our Verdict
Bose SoundLink 2 Wireless
Sennheiser HD 4.50 BTNC
The Bose SoundLink 2 Wireless are slightly better wireless headphones than the Sennheiser HD 4.50 BTNC. The Bose are much more comfortable and have a better-balanced sound profile. On the other hand, the Sennheiser block out more background noise thanks to their ANC feature, feel more stable on the head, and have a slightly longer battery.
