Our Verdict
Sennheiser HD 4.40 BT Wireless
Sennheiser HD 4.50 BTNC
The Sennheiser HD 4.50 are more versatile headphones than the Sennheiser HD 4.40 BT due to their ANC feature, which makes them suitable for commuting and at the office. Other than that, these two models are practically the same and perform quite similarly. The HD 4.40 are a bit less tight on some heads, which can be more comfortable for people with bigger heads.
