Our Verdict

Sennheiser PXC 550 Wireless

Sennheiser HD 4.50 BTNC

The Sennheiser PXC 550 Wireless are better headphones with more features than the Sennheiser HD 4.50. The PXC 550 have a more comfortable fit, touch-sensitive controls, a longer battery life, a better-balanced default sound profile, and more control over their audio profile and noise cancelling. On the other hand, the HD 4.50 have a slightly better isolation performance, thanks to their tighter over-ear fit.
