Sennheiser HD 660S2 Wired Over-Ear Headphones

Sennheiser HD 660S2 Wired Over-Ear Headphones
Enjoy your music on a totally new level with the HD 660S2 from Sennheiser, the improved successor to the HD 660S with audiophile specs and greatly enhanced bass response. The HD 660S2 delivers a deeply moving auditory experience thanks to features like an optimized steel mesh surround, improved transducer airflow, and lighter weight, higher impedance aluminum voice coils, which deliver more impact and extended sub-bass performance, so you can hear the lowest pianos notes and the deepest bass drum hits without sacrificing comfort or natural sound reproduction.

The open-back design and ultrasoft velour earcups of these over-ear headphones ensure extreme comfort during extra-long sessions, and perfectly channel-matched drivers within ±1 dB provide a truly intimate, high-fidelity listening experience. The HD 660S2 comes with two detachable cables in 1/4" unbalanced and 4.4mm balanced flavors, and the headphones also include a handy 1/4" to 3.5mm adapter and a convenient carry pouch.

• More Impact and Emotion
  Sub bass expands the entire sound. In doubling the sound pressure at the lowest frequencies, Sennheiser has retained extraordinary precision and balance throughout the sub-bass, mid-bass, and beyond.
  Extension on the low-end changes everything by creating more space for the sound. Against a deeper backdrop, highs feel more brilliant, the soundstage deeper, and the emotions stronger.
• Headphones that Feel as Great as They Sound
  The velour earpads of the HD 660S2 offer a tactile pleasure with just the right amount of tension for proper acoustic positioning and supple padding. The headband remains comfortable and unobtrusive during listening.
  The open-back design provides a comfortable climate for long sessions, while the low total weight and ergonomic headband minimize fatigue. Combined with excellent build quality, the experience is as physically pleasing as the warm, non-fatiguing sound.
• Update to a Legend
  High-end Sennheiser headphones have long been benchmarks for balanced, natural reproduction. The HD 660S2 shares visible and audible DNA with the HD 600, HD 650, and HD 660S. Its revised coil matches the 300-ohm impedance of the HD 600 and HD 650.
  The new coil delivers higher magnetic force and improved electrical dampening for cleaner impulse response. A more compliant surround lowers the resonant frequency to 70 Hz, resulting in greater precision, speed, resolution, and doubled sound pressure at the lowest frequencies.
• Key Technical Highlights
  Optimized airflow around the transducer to reduce air leakage and increase low-frequency acoustic pressure.
  Lightweight Duofol aluminum voice coils with 300-ohm impedance for improved damping and detail retrieval.
  Twice the sound pressure at 20 Hz compared to previous models for greater low-end impact.
  Stronger response above 5 kHz for enhanced clarity and smoother, more natural reproduction.
  Powerful vented magnet system to minimize distortion.
  38mm high-performance dynamic drivers.
  Steel mesh baffle for controlled permeability and natural bass response.
  Excellent balance and superior imaging through matched acoustic systems.
