Sennheiser HD 400 Pro
The open-back dynamic drivers deliver a neutral 6Hz–38kHz response with 120Ω impedance for accurate mixing. Soft velour ear pads and a 240g weight ensure all-day comfort, reinforced by a durable coiled cable. Best for studio engineers and budget-conscious mixers requiring precise monitoring, not for calls or noisy environments.
