Sennheiser's HD 380 Pro headphones offer a closed circumaural design that makes them perfect for monitoring in studio and live sound environments. The design elements provide up to 32dB of noise attenuation, allowing you to clearly hear what you're monitoring. The HD 380 Pro utilizes Sennheiser's Eargonomic Acoustic Refinement (E.A.R) design, a proprietary system that channels audio directly into the listener's ears, providing the best sound possible. Comfort during long listening sessions is nearly as important as sound quality, and the HD 380 Pros are very lightweight and super- comfortable.
