Sennheiser HD 650

Systems with narrow tolerances (± 1 dB), hand-picked in pairs Highly optimised magnet systems for minimum harmonic and intermodulation distortion High-quality titanium/silver finish A specially developed damping element, made from fine acoustic metal mesh, ensures a precise damping over the entire diaphragm surface, highly constant in all climates. Specially modulated connecting cable (detachable) made from highly conductive OFC copper, with very low handling noise, i.e. low structure-borne sound sensitivity Extremely lightweight aluminium voice coils ensure excellent transient response Gold plated 1/4" jack plug with adaptor lead to 3.5 mm jack plug Specially designed acoustic silk ensures precision damping over the entire frequency range and helps to reduce THD to an incredible 0.05 percent Improved frequency response is 10 39,500 Hertz ( 10 dB) Hand-selected matched driver elements; Highly optimized magnet systems for minimum harmonic and intermodulation distortion High power neodymium magnets deliver maximum efficiency; 3.5 millimetre jack plug. Frequency response (Headphones):10 41000 Hz Lightweight aluminum voice coils for very fast transient response Cable length 118 inches Specially designed acoustic silk ensures precision damping over the entire frequency range and helps to reduce THD to an incredible 0.05percent Improved frequency response of 10 39,500 Hertz ( 10 dB) for rich sound Hand selected matched driver elements High power neodymium magnets deliver maximum efficiency Lightweight aluminum voice coils for very fast transient response
