Introduction: Exceptional Closed-Back Sound

Who says closed-back headphones can’t sound that open? The closed-back HD 620S is for audio enthusiasts seeking a distraction-free listening experience without compromising on natural, airy, and detailed sound. Featuring a remarkably open baffle and angled transducers, it replicates the spatial imaging of loudspeakers while keeping listening sessions secluded.

Superior Design and Features

Closed-back Excellence: Closed-back headphones with steel-reinforced ear cup covers for distraction-free listening sessions.
Precision Sound: Reference-grade 42 mm angled transducers with a 38 mm diaphragm deliver speaker-like imaging with natural detail retrieval and an expansive soundstage.
Enhanced Clarity: Ultra-light 150-ohm aluminum voice coil for enhanced clarity and accuracy in audio reproduction.
Comfort and Durability: Lightweight chassis with steel-reinforced headband sliders and artificial leather ear pads with internal venting for long-term durability and all-day comfort.

Secluded Listening Experience

Enjoy undisturbed privacy while listening to exceptional open, natural sound. The HD 620S lets you experience detailed, spacious sounds like never before in closed-back headphones. The stainless-steel reinforced ear cup covers not only add timeless appeal but also provide a private listening session regardless of your surroundings. Ideal for those who prefer sofa concerts over kitchen talks, offering a distraction-free experience with true-to-life vocals and natural, airy sound.

Innovative Closed-Back Design

Open sound in a closed-back design might seem impossible, but the HD 620S makes it a reality. Combining the DNA of the HD 600 and 500 series, the HD 620S brings the best of both headphone families to a closed chassis. The reference-grade 42 mm angled transducers with a 38 mm diaphragm and ultra-light 150-ohm aluminium voice coil deliver exceptional impulse response, expanding the stereo image to an almost panoramic soundstage. This unique design preserves the detailed, smooth sound the 600 series is known for, setting a new standard for closed-back headphones.

Comfort and Longevity

The HD 620S offers timeless design, function, and comfort. The lightweight chassis is bolstered by premium touches that ensure its unique acoustic signature for years to come. Robust, steel-reinforced headband sliders and ear cup covers add long-term durability. In contrast, spacious ear cup covers and supple ear pads made from artificial leather provide superb acoustic isolation and all-day comfort. The HD 620S is ready for hours of fatigue-free, intimate listening.

Immersive Listening for Any Passion

Who doesn’t sometimes want to just switch off and become immersed in their own world undisturbed? With the HD 620S, you can stay in the same room without compromising on privacy or natural, expansive sound. Whether you love gaming, amateur music production, or simply listening to exceptional audio, the HD 620S elevates your experience with extraordinary detail retrieval and spatial awareness.

Understanding Frequency Response

Reference sound in a closed chassis: The frequency is shown in Hertz (Hz) on the X-axis, with bass response from 20-300 Hz, vocal range from 300 to 3000 Hz, and treble from 3000 to 20,000 Hz. The Y-axis shows relative loudness in dB SPL. The HD 620S offers a bass response louder than the HD 600, resulting in a closer to neutral, true-to-life sound.
