Our Verdict
JBL Live 650 BTNC Wireless
Sennheiser HD 450BT Wireless
The JBL Live 650 BTNC are better overall performing over-ear headphones than the Sennheiser HD 450BT Wireless. The JBL are more comfortable, have more intuitive controls, and feel better built. They have a more neutral and balanced sound too, and their ANC feature is a bit better than that of the Sennheiser. They also have a slightly more comprehensive companion app, their integrated mic performs better, and they come with an in-line mic. However, the Sennheiser have a slightly better battery performance and they leak less sound.
