Open sound with 38mm drivers

The Sennheiser HD 550 use 38mm dynamic drivers with an impedance of 150 Ohm. The drivers are angled within the earcups to support a spatial sound delivery. The frequency range is from 6Hz to 39.5kHz, and the resulting tuning focuses on balanced and clear reproduction. The sound performance offers strong bass, natural mid-range frequencies and an extended high-frequency response. The open-back construction contributes to the airy character of the reproduction and a natural perception of the soundstage.

Lightweight design for long listening sessions
