HD 300 PRO enables neutral, delicate high-resolution sound with all the details you need to make informed decisions about your mix. Experience remarkably detailed, exceptionally natural, three-dimensional audio. No matter what your project, the HD 300 PRO is designed to give you premium tools to make it sound its best—whether you’re in the studio or mixing live sound.
The HD 300 PRO is ideal for composing, playing, and editing music. Its frequency response is linear, ensuring neutral transparency. The highly sensitive transducers keep distortion to a minimum, so you know what you’re hearing through the headphones is a true representation of your sound. In addition, these headphones’ depth of detail is unaffected by high sound pressure levels, meaning they work just as well working with drums and other loud sound sources…no matter how extreme your audio environment, the HD 300 PRO maintains a delicate, precise sound pattern.
When listening lasts for hours, comfort is just as crucial as sound quality. The HD 300 PRO’s around-the-ear design provides reliable protection from very loud ambient noise, isolating your mix and preserving your hearing simultaneously. The viscoeleastic earpads are so comfortable that your focus stays on your sound, not the headphones it’s coming from.
