Hello Head-Fi!
Our HD 600 audiophile headphone series is growing again today, as we proudly introduce the HD 620S: a purist headphone created for head-bobbing listening sessions when seclusion from the outside world is a must. It carries forward some of the most desired sonic characteristics of the family: superb texture reproduction, intimate vocals, and distortion-free sound at practically any listening level…with a modern twist that sounds unexpectedly…open! Are you looking to add an engaging, high-performance set of sealed cans to your collection? Let’s take a closer look.
Just you and your music
The heart of the HD 620S is all 600 series; a custom-tuned 42mm dynamic transducer with a 38mm diaphragm and 150-ohm impedance, made at our state-of-the-art Tullamore factory. Its DNA has been evolved to defy the boxy assumptions of the closed back format. Its high damping factor and speedy aluminum voice coil reproduce transients and elongated instrument tails effortlessly, letting the listener soak up the details of musical passages as they enter and exit the recording. The modernized tuning is a distinct and unique flavor to the family, "unveiling" nuance and clarity while nestled inside an isolating earcup that further deepens the black backdrop audiophiles crave. This acoustic chamber is where the fun begins…
Take a panoramic
The HD 620S harnesses an iconic Sennheiser chassis (HD 560S, HD 598, HD 555 to name just a few), lauded for its instant “sweet spot”, and long-term wearing comfort...but most importantly is its transducer geometry; the angled baffle recreates the triangular imaging of a loudspeaker setup for exciting panoramic imaging that pulls the listener right into the front-row. The imaging, which is uncharacteristically wide for a closed headphone, utilizes a remarkably open baffle and steel plate that is both an effective isolator from the outside world, and facilitator of internal reflections crucial to the open sensation.
While open headphones are an audio purist staple, closed headphones are invaluable for critical listening when isolation from the world around the listener is essential. Audiophiles like us have long been accustomed to sacrificing wide imaging and engaging dynamics in order to mitigate distractions. No more – the HD 620S lets you unpack your favorite music without disturbing your roommates, partners and even coworkers – who can remain oblivious to your hi-fi passion. A combination of selectively absorbent and reflective build materials manage soundwaves with a minimum of damping behind the surround. That aforementioned surround was adopted from the HD 660S2 and is highly compliant for deep bass with punch and clarity. Even the synthetic leather earpads play a role in disguising the closed listening experience – the perforations and material densities were spec’d to absorb unnecessary reflections in the front volume, effectively remanding the “honk” tone inherent in many closed designs.
Built to last
The HD 620S was made for the long haul with a new metal-reinforced headband and earcup housings. The band and earpads provide a snug-but-luxurious fit, tensioned to block out the outside world for extended listening sessions. The twist-lock single-sided cable terminates to a single-ended 3.5mm / ⅛-inch plug, with 1.8 meters (~6 feet) of length between terminations. A 6.3mm / ¼-inch adapter is included for connection to a huge variety of amplifiers, soundcards, interfaces, and mobile devices. Available later this summer, an optional, balanced 4.4mm cable will let you tap into the growing range of hi-fi devices now supporting the connector such as amplifiers, DAPs, and DAC-amps. This cable platform adds to the versatility of the HD 620S, letting you connect existing 1st and 3rd party cables at varying lengths and options such as those with in-line microphones.
The HD 620S begins shipping on June 6th 2024—it is available to pre-order from select retailers and at sennheiser-hearing.com. We will host a product tour (to be announced shortly), a Q&A with the HD 620S product manager, and have some additional HD 620S content coming to Head-Fi leading up to the availability date.
@ericpalonen will be here to help answer any questions, with an HD 620S at the ready.
