Play By Your Own Rules
Sennheiser Signature Sound
The HD 660S2 headphones feature an ultra-light aluminum voice coil with a 300-ohm impedance, ensuring excellent impulse response and exceptional sound quality. Meticulously engineered 42mm high-performance transducers with a vented magnet system provide minimal distortion and precise air displacement control through steel mesh damping.
Deep, Punchy Bass
These headphones excel at reproducing deep, clear bass and low frequencies, allowing you to experience the full spectrum of sound, from the lowest piano notes (27.5 Hz) to the powerful kick of a bass drum (45-60 Hz) as if you were in the recording studio.
Comfort and Ergonomics
Designed for comfort during extended listening sessions, the open-back design offers excellent breathability, and plush ear cushions maximize comfort. Crafted in Germany and made in Ireland, the HD 660S2 headphones deliver a frequency response from 8 Hz to an impressive 41,500 Hz.
