OVERVIEW:
When the music matters the most: The HD 650 reproduces the subtle details in your music with the same confidence as the highlights.
The (high) definition of smooth: Expertly balanced acoustics, luxurious construction and timeless design. 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. For the hi-fi enthusiast that prioritizes engaging sound quality the HD 650 is an instant upgrade.
Smooth response and dimensional soundstage: Open earcups provide each and every soundwave ample room to expand as they would in nature. 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: overall treble and low-frequency presence are effortless while midrange is reproduced with lifelike composure—none sacrificing their organic roots to get there. Modern high-resolution sample rates benefit especially well from the HD 650’s willingness to reveal subtle nuances without resorting to over-hyping the treble range. Each transducer manufactured is measured against rigid specifications and paired with a perfect match for consistent representation of the entire frequency spectrum in both channels. By reducing variances between left and right channels, the headphone reproduces mastering-grade sound independent of room acoustics or loudspeaker positioning.
Made with more in mind: Combines the best of modern transducer manufacturing with the attention to detail required to handle a wide variety of acoustic materials. 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. Our production tolerances are extremely tight, ensuring that your HD 650 experience is consistent with those all over the globe, whenever or wherever it was purchased. For example, the resonators feature stainless steel mesh to guarantee uniform performance after manufacturing. Even better, most parts on the HD 650 are modular, making them a dream to keep as your go-to hi-fi playback headphones for as long as you cherish them. From the velour pads to the earcup grille pattern, each component was crafted to guarantee a next-level personal sound experience so you can enjoy your music even more.
It's all about connection: Comes with a detachable, impedance-matched cable, stereo connector with audiophile-standard plug and premium adapter. 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. At 9.8 feet / 3m long, it offers unencumbered listening on gear deep within your shelves or in a favorite listening chair. A premium adapter is included to reduce the 6.3mm to 3.5mm / ⅛-inch for plugging into countless other audio devices.
