With these groundbreaking closed dynamic headphones, passionate music lovers can now enjoy their music at an audiophile level wherever they please, at home or on the move. Featuring unique glass transducer covers that minimize resonances, the HD 820 are simply the most transparent-sounding closed headphones in the world, extending the boundaries of what has been achieved in sound reproduction with closed type headphones up to now.
FEATURES
- The sound field of the HD 820 is vivid, wide, transparent, and natural.
- The transparent concave glass reflects the sound waves from the rear of the transducer to an absorber, which results in minimal resonance.
- Extra comfortable handcrafted ear pads that insulate the listener from ambient noise.
- They come with a specially tuned symmetrical, impedance-matching cable with low capacitance and a balanced 4.4 mm gold plug for superior characteristics in contact resistance, and thus in sound.
