Sennheiser HD 660S2
Featuring 38mm dynamic transducers with a 300-ohm impedance and a frequency response from 8 Hz to 41.5 kHz, the open-back design delivers low-distortion sound with a distinct sub-bass emphasis. Its plush padding and steel-mesh damping yield high comfort and controlled airflow for fatigue-free listening, with detachable 1.8m cables and a 4.4mm balanced connection. Best for audiophiles and studio monitoring where precise imaging and extended bass are critical, but its 14/100 call score makes it unsuitable for phone calls.
