About the HD650

The Sennheiser HD 650 is a premium open-back dynamic headphone developed from the award-winning HD 600, combining streamlined design with richly-detailed sound reproduction. Manufactured in Ireland, these headphones feature hand-paired drivers matched according to detailed measurement values to ensure precise channel matching. The 42mm transducer with 38mm diaphragm and aluminum voice coil is specifically tuned for extended critical listening. With their expertly balanced acoustics and lack of excessive treble boost, the HD 650 reproduces subtle musical details and is ideal for both professional studio operators and audiophiles seeking high-resolution sound. The lightweight design (269g without cable) and soft velour ear cushions enable hours of fatigue-free listening. The detachable cable is made from highly conductive OFC copper, optimally matched for impedance, with a 3-meter length providing freedom of movement. Note: The HD 650 has been discontinued by Sennheiser, though some stock may remain available through retailers.
