Sennheiser - HD 660S2

Sennheiser - HD 660S2

Nothing makes music feel dramatic like powerful bass. The extremely precise yet non-fatiguing sound of the HD 660S2 now delivers even more impact with extended sub bass.

More impact and emotion

Breathtaking resolution and precision take you closer than ever to instruments and vocalists. Yet the sound is natural and balanced, never harsh or brash. Sub bass expands the entire sound. In doubling the sound pressure at the lowest frequencies, we’ve 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 emotions stronger.

Feature Set includes:

► Ultra-light aluminum voice coil with 300-ohm (Ω) impedance for excellent impulse response

► Uniquely powerful vented magnet system for minimized distortion

► Outstanding quality designed in Germany, made in Ireland

► Intimate sound with great timbre and deep, accurate sub bass

► Plush ear cushions and open design for maximum comfort
