Sennheiser HD 300 Pro Monitoring Headphones

Sennheiser HD 300 PRO Closed-Back Studio Headphones

Precision Monitoring for Mixing, Recording, and Professional Audio Workflows

The Sennheiser HD 300 PRO headphones are built for audio professionals who demand accurate sound reproduction, comfort, and noise isolation during long sessions. Designed with closed-back, over-ear (circumaural) construction, these headphones provide a focused listening environment ideal for mixing, editing, tracking, and live monitoring.

Clear, Detailed Sound Across the Full Spectrum

With a wide frequency response from 6 Hz to 25 kHz, the HD 300 PRO delivers exceptionally clear and balanced audio, making it easy to hear subtle details in your mix. The dynamic drivers are engineered for a linear frequency response, ensuring true-to-source sound across lows, mids, and highs.

Whether you're working on precise EQ adjustments or monitoring complex layers in a mix, these headphones give you the accuracy and consistency needed for professional results.

Exceptional Noise Isolation Without Active Technology

Thanks to their closed-back design and acoustically isolated earcups, the HD 300 PRO headphones provide up to 32 dB of passive noise attenuation. This means you can stay focused even in loud studio or stage environments, without the need for active noise cancellation.

This level of isolation not only improves concentration but also ensures that you hear only what matters, your audio.

Distortion-Free Even at High Volumes

Built to handle the demands of high-pressure environments, the HD 300 PRO remains distortion-free even at sound pressure levels up to 123 dB SPL. This makes them suitable for a wide range of applications, from critical listening in the studio to loud stage monitoring during live performances.

Comfortable for Long Sessions

The HD 300 PRO features viscoelastic memory foam earpads that mold to the shape of your ears for superior comfort, even during extended listening sessions. Combined with a lightweight, ergonomic headband design, these headphones help reduce fatigue, letting you stay productive for longer.

The carefully designed earcup structure not only enhances isolation but also contributes to all-day wearability by minimizing pressure points and improving airflow.

Flexible and Studio-Ready

The headphones come with a 4.9-foot detachable cable that connects via a standard 3.5 mm jack, making it compatible with most audio interfaces, mixers, and portable devices. A ¼-inch adapter is also included, allowing seamless integration with professional studio equipment.

The cable is replaceable, adding to the long-term durability and serviceability of the headphones.
