Sennheiser’s line of open-backed headphones has grown a bit over the years, but the HD 650 remains a stalwart of the brand that’s been around for close to two decades.
The HD650 uses an exclusive 42mm transducer model (with 38mm diaphragms) and was tuned by Axel Grell. Features: 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 inter modulation 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. Impedance: 300 ohms. Total harmonic distortion: <0.05%. Remark: Some signs of cosmetic wear in the foam net pads.
