Optimal Design for Studio Sessions

A pair of Sennheiser’s HD 400 Pro Studio Reference Headphones is the perfect studio companion to accompany you during your recording, editing, mixing, and mastering sessions. With its open-back design, 120-ohm unique polymer-blend transducer diaphragm, and high-power drive magnet and damping system, the HD 400 Pro’s internal engineering proves reliable time and time again for deeper bass, quality distortion migration, and a natural and accurate listening experience. This superior sound can be partially attributed to its open earcups and angled transducer design, revealing a wide soundstage that works to replicate the optimal listening positions of the top recording studios in the business. Producers here at Sweetwater also appreciate how Sennheiser keeps quality construction and comfort at the forefront, offering a lightweight but durable housing with soft velour earpads to make those longer sessions more bearable.

My expectations are met

Got this recently and so far very happy with my investment. Using it with Dearvr, to me it a complete solution for monitoring.

Also keep in mind, the HD 400 Pro is different sounding from the 560s which are manufactured after Jan 2023.
Rated 5/5

Lightweight & comfortable

These open back headphones seem to have a flat frequency response and allow me to hear my surroundings while mixing.
It feels more like listening to monitors than being isolated with earbuds or something.
Comfortable and light enough to wear for a while without fatigue.

I love them

I really love these headphones. Glad I bought them. They are perfect for mixing and do not give ear fatigue plus they're not too expensive. Will see how long they hold up.

And of course a BIG shoutout to Sweetwater. Been using these guys for I think over a decade and they never miss when it comes to customer satisfaction. Thank you Jānis Spunde and your whole team!

Great Reference Headphones

My least favorite things about mixing in headphones are pretty much all corrected when using these. The angled transducers provide the best stereo image that I have heard in headphones, and even provide a sense of phantom center. The frequency response is nearly flat, providing a very similar response to some of the well treated control rooms I've mixed in before. As a former user of the Beyerdynamic DT770 80 Ohm model, these provide a much more transparent low end response, and the high end is much less hyped (which is great). Overall these are my new favorite headphones and a very useful tool to have.

Excellent headphones.

They arrived quickly. Once I got used to the open back headphones, they are great to use and the fit over my ears perfectly. Another great product from Sweetwater.

From their studio-standard MD 421 II drum mic to their trusty headphones and ultra-reliable wireless systems, there are countless good reasons why the artists and engineers here at Sweetwater are quick to recommend Sennheiser products. In our personal studios, you'll find plenty of HD 280 Pro headphones, e609 Silver cab mics, and other staples, while many of us rely on EW wireless in-ear systems onstage. Our long association with Sennheiser means we constantly have their latest products in stock and in our hands, so we're ready to tell you all about them. If you're looking for Sennheiser gear, then get the information you need from people who use it - trust your Sweetwater Sales Engineer.
