Sennheiser HD 620S – Available at OzTech Emporium in Australia

Reference-Grade Audio in a Closed-Back Design

Exceptional Sound & Design

The Sennheiser HD 620S feature 42mm dynamic transducers with a 38mm diaphragm and an ultra-light 150-ohm aluminum voice coil, delivering detailed, natural sound with balanced bass, clear mids, and airy treble across a 6Hz–30kHz frequency range. The closed-back design, with an open baffle and angled transducers, creates a panoramic soundstage rare for its class, rivaling open-back models while offering passive noise isolation. Weighing 326g without the cable, the over-ear headphones use artificial leather earpads and a steel-reinforced headband for comfort during long sessions, though some note slight pressure over time. Available in Black, the sleek design with stainless steel earcup covers is durable but may show smudges.

Connectivity & Compatibility

Equipped with a detachable 1.8m cable with a 3.5mm plug and a 6.3mm adapter, the HD 620S connects to hi-fi systems, DACs, or mobile devices. The 150-ohm impedance ensures compatibility with most sources, though a headphone amp enhances dynamics. An optional 4.4mm balanced cable is available for high-end setups. The cable’s twist-lock mechanism ensures secure connections, but some users report it’s slightly stiff. No wireless or app support, focusing solely on wired, high-fidelity audio. Total harmonic distortion is low (<0.05% at 1kHz, 90dB SPL).

Build & Features

Built with a lightweight chassis and steel-reinforced sliders, the HD 620S combine durability with a premium aesthetic. The closed-back design, inspired by the HD 600 and 500 series, uses meticulously tuned baffles for open, natural tonality, while the compliant surround from the HD 660S2 enhances bass response. The package includes a carry pouch and adapter. Passive isolation reduces ambient noise effectively, though not as strong as ANC models. Users praise the spacious sound for genres like jazz or classical, though some note a slight bass emphasis compared to open-back siblings. A 2-year warranty ensures reliability.
