Sennheiser HD 4.50 BTNC vs Sony WH-1000XM3 Wireless

The Sony WH-1000XM3 Wireless are better headphones than the Sennheiser HD 4.50 BTNC. Most notably, the XM3s' ANC is excellent and blocks more ambient noise than the HD 4.50 BTNC. Their overall audio reproduction is more accurate, but with a slightly overemphasized bass, which can be EQ’ed inside their great app. The XM3 are also more comfortable and better-built than the Sennheiser. On the other hand, the HD 4.50 can connect to two devices simultaneously. Some may also prefer their control scheme with physical buttons over the touch-sensitive surface of the WH-1000XM3, which may be unresponsive in colder temperatures.
