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 clear reproduction of audio, doing so while offering up to 32 dB of passive noise reduction. Their dynamic drivers offer a linear frequency response throughout the entire spectrum. They are constructed 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.

Sennheiser HD 300 PRO Reviews

Excellent sound, noise isolation, and quality!

By Jonatha
Rated 5 out of 5

In searching for a new pair of headphones that would have better sound isolation than my usual pair, I tried on the Sennheiser HD 300 Pro headphones at a local gear shop and knew they were the ones. I work from home and share an office space with my housemate who frequently takes work calls and meetings; these headphones mean that I can put on music, a show, or a movie and not be distracted by the calls while I work. They're also useful for recording, since the design of the headphone results in very little - if any - audio leak from the cups. I also haven't noticed any pressure issues from long wear sessions, and can wear them with my glasses without feeling compressed. The audio quality is clear and while I ended up downloading an EQ add-on for my PC, I would also be happy to use them as-is. All in all, I am very happy with my purchase. I will be curious to see how these headphones hold up over time and how soon the ear pads will need to be replaced. My wallet wishes that these were sub-$150 rather than $200, but compared to everything else I've tried at this price point and above, they have been well worth the purchase and suit my needs.

Weak highs

Very weak on the high end which is surprising not only for monitors but for Sennheisers in general. I'll find a use for them but they will not my main cans as I intended them to be. I cannot recommend this product. 3 stars for build quality and good mids and bottom.
