HD 650

A benchmark for total audio immersion.

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.

It’s all about connection

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
