Legendary Audiophile Sound with Enhanced Bass
The Sennheiser HD 660S2 feature 38mm high-performance transducers with an ultra-light aluminum voice coil, delivering natural, balanced sound with extended sub-bass, precise mids, and smooth treble across an 8Hz–41.5kHz frequency range. Optimized airflow and a revised 300-ohm coil double the sound pressure at low frequencies (e.g., 27.5Hz piano notes or 45-60Hz bass drum kicks), retaining clarity without distortion (THD <0.04% at 1kHz, 100dB). The open-back design offers a spacious soundstage but leaks sound, unsuitable for noisy settings. Weighing 260g, the over-ear headphones include plush velour earpads and an ergonomic headband for comfort during long sessions, though some note mild warmth. Available in Black, the design is sleek but may show earpad wear over time.
Equipped with detachable 1.8m cables (6.3mm unbalanced and 4.4mm balanced) with para-aramid reinforcement, the HD 660S2 connect to hi-fi systems, DACs, or amps. The 300-ohm impedance requires a robust source for optimal performance, though portable devices can drive them at moderate levels. A 6.3mm to 3.5mm adapter is included, but some users report the cable’s lead connection to the headphone needs careful handling. No wireless or app support, focusing on wired, audiophile-grade audio.
Designed in Germany and made in Ireland, the HD 660S2 feature a vented magnet system with steel mesh damping to minimize distortion and a 70Hz resonant frequency for enhanced bass response. The package includes a carry pouch, cables, and adapter, though some wish for a hard case. The open-back design and lightweight construction prioritize soundstage over noise isolation, ideal for quiet environments. Users praise the neutral sound with enhanced sub-bass for genres like classical or bass-heavy tracks, though some find the cable stiff. A 2-year warranty ensures reliability.
