High Quality:

• Supra-aural design rests lightly on the ear, creating a controlled environment for better sound. Driver is positioned the correct distance from the ear canal
• 30mm diameter drive units are larger than many headphones for deeper bass, lower distortion and wider dynamic range; bass response extends down to a low 18 Hz
• 500 mW power handling stands up to day-in, day-out use at high output levels
• Uses Neodymium magnets for maximum energy and minimum size. Packing more magnetic energy per ounce than conventional Ferrite, Samarium Cobalt or Aluminum magnets, Neodymium helps produce ample sound output--100 dB/mW sensitivity
• Oxygen-free copper cord for maximum conductivity and minimum noise; conducts electricity better than conventional copper
• Gold-plated plugs resist corrosion for high conductivity and low noise

Conveniences:

• Folding design permits easy storage and easy portability in a briefcase or equipment bag
• Reversible earcups enable single-sided monitoring flexibility
• Wide, molded headband distributes the headphone's weight over a wide area thus reducing pressure. Provides comfortable listening for hours on end.
