The Sennheiser HD 300 Pro Studio Monitoring Headphones, engineered with signature precision, are premium studio monitoring headphones that deliver neutral, high-resolution audio so that you can hear every nuance of your mix. The HD 300 Pro is designed for audio professionals and musicians who demand pristine sound quality, superior comfort, and a lightweight, portable form factor.

Hear Every Detail With Unmatched Accuracy

The HD 300 Pro's wide 6Hz-25kHz frequency response and low 64 ohm impedance provide a transparent sonic landscape brimming with depth and detail. Its neodymium magnets and lightweight diaphragms reduce distortion for a powerful yet natural sound even at high volumes. The result is a three-dimensional quality that lets you pinpoint the location of every instrument and vocal in your mix.

Block Out Distractions With Noise Isolation

The HD 300 Pro's circumaural design envelops your ears in comfort while blocking up to 32dB of ambient noise. Its viscoelastic earpads evenly distribute pressure and seal out external sounds so you can focus on what matters most—your music. A single-sided, detachable cable further reduces mechanical noise for an ultra-quiet listening experience.

Designed for Durability and Portability

With a rugged yet lightweight build, the HD 300 Pro is ready for use in any studio or mobile setup. Its sleek, matte black esthetic is complemented by a durable metal headband and hinges built to withstand the rigors of daily use. When folded flat, the headphones slip easily into the included carrying pouch for storage or transport between recording sessions.

Premium Comfort for Long Sessions

The HD 300 Pro's ergonomic design provides exceptional comfort for extended mixing and monitoring. Its padded headband and rotatable earcups evenly distribute weight across your head while conforming to the shape of your ears. With premium materials and replaceable parts, the HD 300 Pro delivers a first-class experience that stands the test of time.
