Our Verdict
Sennheiser HD 4.50 BTNC
Sony WH-XB900N Wireless
The Sennheiser HD 4.50 BTNC are marginally better than the Sony WH-XB900N. They have a more neutral sound profile, but the XB900N are more comfortable and have a better control scheme. The Sennheisers can be connected to two devices simultaneously and have a better ANC feature as well. On the other hand, the Sonys feel slightly better made and have a dedicated companion app with access to a graphic EQ.
