The Sennheiser HD 380 Pro Headphones exceed the expectations of the most demanding industry professionals. Exceptional sound quality is delivered via large drivers which provide a 8Hz – 27kHz frequency range, a maximum 500mW input power and a punchy 110dB Sound Pressure Level (SPL). Sennheiser’s Eargonomic Acoustic Refinement (E.A.R) technology utilises Duofol diaphragms to reduce distortion and deliver the detail-rich audio signal directly into your ears. A padded headband and cushioned faux leather lined earcups provide 32dB of external noise reduction to ensure comfort during extended use and an uncontaminated listening experience. A detachable single sided coiled cable resists tangle and delivers a variable length for listening versatility. The Sennheiser HD 380 Pro Stereo Headphones also come with a convenient slimline carry case to protect your investment when not in use.
