Sennheiser HD 650 – Available at OzTech Emporium in Australia

Audiophile-Grade Open-Back Headphones

Exceptional Sound & Design

The Sennheiser HD 650 feature 42mm transducers with a 38mm diaphragm and aluminum voice coils, delivering natural, detailed sound with warm bass, smooth mids, and crisp treble across a 10Hz–41kHz frequency range. The open-back design creates a wide, dimensional soundstage, ideal for critical listening, though it allows sound leakage and minimal noise isolation. Weighing 260g without the cable, the over-ear headphones use velour earpads and a padded headband for lasting comfort, though some note slight warmth during extended sessions. Available in grey with a titanium/silver finish, the design is timeless but may show wear on the earpads over time.

Connectivity & Compatibility

Equipped with a detachable 3m OFC copper cable with a 6.3mm stereo jack and a 3.5mm adapter, the HD 650 connects to headphone amps, hi-fi systems, or DACs. The 300-ohm impedance requires a powerful source for optimal performance, though portable devices can drive them at moderate volumes. The cable’s low handling noise and modular design enhance durability, but some users note the lack of balanced cable options in the box. No wireless or app support, focusing purely on wired, high-fidelity audio.

Build & Features

Crafted in Ireland with tight production tolerances (±1dB), the HD 650 feature a stainless steel mesh resonator for consistent sound and modular components for long-term use. The open-back acoustic design and lightweight aluminum voice coils ensure precise transients and low distortion (THD <0.05% at 1kHz, 1V). The package includes a premium carry case and adapter. Lacking active noise cancellation, they rely on a relaxed fit for comfort, with some users noting the need for occasional earpad replacements. A 2-year warranty ensures reliability.
