Our Verdict
Sony WH-XB900N Wireless
Sennheiser HD 450BT Wireless
The Sennheiser HD 450BT Wireless and the Sony WH-XB900N Wireless are similarly performing headphones, but the Sennheiser have a slight edge. The Sennheiser have a more neutral sound profile, their ANC feature can isolate more bass noise, and their leakage performance is better. They also charge in less time, even if their battery life doesn't last as long as the Sony, and they can be paired with up to two devices at a time. The Sony, on the other hand, feel better built, their controls are easier-to-use, and their companion app is better. They also have a better performing integrated microphone, and some users may prefer their bass-heavy sound.
