The Sennheiser HD300 Pro headphones are a pair of studio monitoring headphones that are perfect for both music producers and performers. These headphones come equipped with an advanced ActiveGard technology that prevents levels from going above 110dB and therefore protects your hearing from dangerously high sound pressure levels, while also providing you with an exceptionally detailed sound and a high level of comfort. The ActiveGard combines with a highly-accurate sound, making the HD 300 Pro headphones a reliable tool for demanding studio sessions.
