The Sennheiser HD-660S2 Wired Over-Ear Headphone is a refined evolution of Sennheiser's open-back reference line, created for audiophiles who want a highly resolving yet musical listening experience. Its dynamic, open transducer design with 38 mm drivers delivers an expansive, natural soundstage with excellent imaging and separation. With a frequency response from 8 Hz to 41,500 Hz and an impedance of 300 ohms, the HD-660S2 reveals subtle low-level details, deep controlled bass, and airy treble that does justice to high-resolution recordings.
Tuned for clarity and low distortion, the HD-660S2 achieves a sound pressure level of 104 dB at 1 kHz, 1 Vrms, with total harmonic distortion kept below 0.04 percent at 1 kHz and 100 dB. Comfortable over-ear ear cups and a lightweight. The included 1.8 m cable terminates in a 6.3 mm jack plug with a 4.4 mm balanced plug option, plus a 6.3 mm to 3.5 mm adapter for flexible connectivity to a wide range of headphone amplifiers, DACs, interfaces, and portable players. Manufactured in Ireland with a precisely controlled 4.5 mT magnetic field, the Sennheiser HD-660S2 offers a premium, open and engaging sound that is ideal for serious music listening at home or in the studio.
