Sennheiser HD 300 PRO Overview

The Sennheiser HD 300 PRO are closed-back circumaural headphones designed for mixing and other pro audio applications. With a frequency response of 6 Hz to 25 kHz, these headphones provide crystal clear sound reproduction, while also offering up to 32 dB of passive noise reduction. Their dynamic drivers offer a linear frequency response across the entire spectrum and are built to remain distortion-free, even when pushed to an SPL of up to 123 dB.

The HD 300 Pro sports viscoelastic earpads that are intended to be comfortable and facilitate extended, prolonged listening sessions. The isolation of the acoustic drivers within the unit's earcups lends to the experience, bolstering passive noise isolation as well as long-lasting comfort. The included, exchangeable cable measures 4.9' and terminates in a 3.5mm connection. A 1/4" adapter is included.
