Dive deeper into your music.

Enjoy your music on a completely new level. An intimate, relaxed sound signature combines with outstanding precision and exceptional comfort — and now, extended sub bass — for a deeply moving experience. The extremely precise yet non-fatiguing sound of the HD 660S2 delivers even more impact with extended sub bass.

With an optimized surround, transducer airflow, and coil our engineers doubled the sound pressure at the lowest octaves. You can feel the lowest note on the piano (27.5 Hz) or the kick of the bass drum (45-60 Hz) as if you were there.

The relaxed tone and open-back design make this extremely comfortable headphone great for long sessions. With warm tuning, smooth treble, and strong bass, the standard-setter for extended listening is now the standard setter for extended bass as well.

AUDIOPHILE SOUND

This warm, inviting signature combined with extended sub bass makes listening uniquely pleasant and rewarding. And with comfort this good, it practically begs you to keep going for endless sessions. That’s how HD 660S2 combines the best of many worlds to give you an intimate experience you won’t want to live without

Natural, relaxed, high-fidelity sound with extra sub bass: Optimized surround and diaphragm with new voice coil with 300-ohm impedance

38mm high-performance transducers built in Ireland: Steel mesh damping follows the driver’s geometry to control air displacement, while the magnetic yoke includes milled air vents for optimal ventilation, which minimizes distortion

Uniquely powerful vented magnet system for minimized distortion

Ultra-light aluminum voice coil with 300-ohm impedance for excellent impulse response

Intimate sound with great timbre and deep, accurate sub bass

EXCEPTIONAL COMFORT

Exceptional comfort and build quality: The open-back design and plush ear cushions offer exceptional breathability for long listening sessions

The velour earpads of the HD 660S2 can only be described as a tactile pleasure

The low total weight and ergonomic headband rule out any potential discomfort on top of your head as well. Combined with excellent build quality made in Ireland, you’ll quickly grow attached to a listening experience that’s as physically pleasing as the warm, non-fatiguing sound at its heart.

Global 2-year warranty offers peace of mind for your audio equipment investment
