The HD 650 is a benchmark for complete audio immersion, reproducing subtle nuances in your music with the same confidence as the highlights. Designed for hours of fatigue-free listening, it is the headphone to reach for when music matters most.

With 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. These open-back headphones are loved by audiophiles for their musical, non-fatiguing sound while still offering an intimate level of detail. As soon as the first note is played, your favorite tracks reveal their true potential, and every moment of that performance becomes an opportunity to react all over again. HD 650 is an instant upgrade for hi-fi enthusiasts who prioritize engaging sound quality.

The HD 650’s signature sound starts with its in-house acoustics. Audiophiles are aware that the best components perform at their best when nothing stands in their way. It’s no surprise that the HD 650’s response and soundstage are smooth – its open earcups allow each and every soundwave sufficient space to expand as they would in nature. Its 42mm transducer uses a 38mm diaphragm and aluminum voice coil, which are specifically tuned for extended, critical listening: overall treble and low-frequency presence are effortless, while the midrange is reproduced with lifelike composure – all without sacrificing their organic roots in the process. High-resolution sample rates benefit most from the HD 650’s ability to reveal subtle nuances without overdoing the treble. 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 the balance of left and right channels, the headphone reproduces audio of mastering-grade regardless of the acoustics of the room or where the speakers are placed.

With the HD 650, every detail was noticed, more music was enjoyed, and most definitely more time was spent listening to music. The HD 650 is manufactured in a state-of-the-art facility in Ireland that combines the best of modern transducer manufacturing with the attention to detail necessary to handle a wide variety of acoustic materials. HD 650 production tolerances are extremely tight, ensuring that your experience is consistent whether you purchase it locally or worldwide. The resonators feature stainless steel mesh to ensure uniform performance after manufacturing. Because of the HD 650’s modular design, you can cherish them for as long as you like as your favorite hi-fi headphones. The earcup grille pattern and velour pads were created to guarantee a next-level personal sound experience so you can enjoy your music even more.

HD 650 comes with a detachable cable that is impedance-matched and has very 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.
