The (high) definition of smooth. The HD 650 has all of the perks of a high-performance sports car and none of the quirks. This open-back headphone is beloved by audiophiles for its musical, non-fatiguing sound while still offering intimate levels of detail. Upon the first note, your favorite tracks reveal their true potential, and each moment of that performance becomes an opportunity to react all over again.
Smooth response and dimensional soundstage. The HD 650’s signature sound starts with our in-house acoustics. Audiophiles know that the best components perform at their peak when nothing stands in their way. The 42mm transducer deploys a 38mm diaphragm with aluminum voice coil specifically tuned for extended, critical listening.
Made with more in mind. Made in Ireland at a state-of-the-art production facility, the HD 650 delivers more: more details discovered, more musicality, and definitely more time for blissful listening.
It's all about connection. Your HD 650 comes with a detachable, impedance-matched cable with ultra-low capacitance. The ¼-inch / 6.3mm stereo connector offers the audiophile-standard plug for connection to devices such as headphone amplifiers and A/V receivers, digital audio players, analog gear, and more.
