Sennheiser HD 300 PRO – professional monitoring headphones with highly sensitive transducers, precision diaphragms, and viscoelastic earpads. It provides high-resolution, distortion-free sound, linear frequency response, and efficient passive noise attenuation. On board, there is a dynamic closed-back design, coiled cable, and extensive performance functions.
Sennheiser HD 300 PRO is an environment for sound creation designed for studio and live monitoring. It features a robust build with field-replaceable parts, from simple audio checks to complex setups. Flexible cabling with single-sided coiled design enables a wide range of configurations – including classics from the Sennheiser ecosystem.
Monitoring is deeply integrated: neutral sound across the spectrum, optimal pressure distribution for comfort, fontanelle recess to reduce fatigue. Audio can be handled in real-time – for precise decisions without distortion. The headphones offer German engineering, replaceable components, and advanced options.
