The gray Bluestar CanSkins are earcup covers designed to deliver enhanced comfort and appearance for Sony MDR-7510 headphones in use on the go or during studio sessions. This pair of covers features soft, breathable synthetic chamois and neoprene rubber sides, allowing a secure fit and improved temperature regulation. Protect your headphones against sweat damage and enjoy longer periods of listening without inducing distortion or dampening. Simply stretch the CanSkins around your existing earcups; no tools required! Freshen them up with a wash in the machine or by hand.
