Headphones Sennheiser HD 660S2

Updating Sennheiser's modern classic HD 660 S model, the HD 660 S2 produces deafeningly precise sound that is at the same time effortless, intimate and relaxed. The model features a redesigned voice coil and 300 ohm impedance, Irish-made 38mm drivers, element-shaped steel mesh and magnetic hangers - all designed and manufactured with excellent sound quality in mind. Thanks to the open structure and plush ear cushions, the headphones offer excellent breathability for long listening sessions.

The characteristic warm and balanced sound is now even more open and transparent. It gains even more impact than its predecessor with a lower-reaching bass reproduction. The sound pressure is doubled in the lowest octaves, so you can literally feel the lowest note of the piano (27.5 Hz) or the bass drum (45-60 Hz) as if you were in the same space. Unstressed sound and open structure together with a very comfortable and sturdy ear frame make the HD 660 S2 headphones perfect for long and enjoyable listening sessions.
