Sennheiser HD 400S Reviews

Just okay

By Matthew
Rated 3 out of 5
Date: 2025-04-24

The sound quality was okay, the build good, but I returned these because the audio cable was not a standard 3.5 connector on the end that goes into the headphone. if it broke or I misplaced it I’d be forced to find or buy from the manufacturer or just be out of luck.

perfect
