HD 660 S2 Hi-fi Open Back Dynamic Audiophile Headphones, Black
HD 660 S2 Hi-fi Open Back Dynamic Audiophile Headphones, Black
Description & Specifications
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 air flow, 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.
The HD 660S 2 is a high performance audio product, and requires an adapter to connect to your mobile phone. For an ultimate audio experience, the HD 660S 2 is best paired with a small DAC or suitable amplifier
