Sennheiser HD620S Closed-Back Audiophile Headphones

HD620S Closed-Back Audiophile Headphones, by Sennheiser.

The closed-back HD 620S is for audio enthusiasts seeking a distraction-free listening experience without compromising on natural, airy and detailed sound. Featuring a remarkably open baffle and angled transducers, it replicates the spatial imaging of loudspeakers while keeping listening sessions secluded. Who says closed-back headphones can’t sound that open?

The HD620S are closed-back headphones with steel-reinforced ear cup covers for distraction-free listening sessions. Reference-grade 42 mm angled transducers with 38 mm diaphragm deliver speaker-like imaging with natural detail retrieval and expansive soundstage.

Ultra-light 150-ohm aluminium voice coil for enhanced clarity and accuracy in audio reproduction, while the lightweight chassis with steel-reinforced headband sliders and artificial leather ear pads feature internal venting for long-term durability and all-day comfort.

Sennheiser believe in giving high-performance audio enthusiasts the purest headphone listening experience possible, even when their surroundings are far from perfect. The closed-back HD620S provides a distraction-free listening without compromising on natural sound.

Where many closed headphones struggle, the HD620S excels, preserving the detailed, smooth sound the 600 series is known for, while providing expansive, panoramic imaging. The HD620S features angled transducers nestled in a remarkably open baffle that increases the airy sound and natural tonality.

Bass and sub-bass are substantial yet meticulously balanced thanks to a compliant surround, which has been adopted from the venerable HD660S2.
