What reviewers said
Sennheiser HD 650
The Sennheiser HD 650 is a wired, open-back dynamic headphone built for serious home listening. It delivers a natural, detailed sound with a comfortable fit, though its sub-bass rolloff and bulky design limit it to stationary use rather than portable or active scenarios. Its replaceable cable and balanced connection option add to its appeal for audiophiles.
