Sennheiser has been the world’s leading professional audio company since 1945. With 75 years of history comes a culture of innovation and a passion for excellence. As a company, they strive to shape the audio world of tomorrow — today. As such, it’s not surprising that they continue to impress us with the recent announcement of the new Sennheiser HD 400 Pro Headphones.
Sennheiser headphones are incredibly reliable, and always provide exceptional, balanced sound. Sennheiser has introduced the HD 400 Pro, which produces a flat frequency response so you can deliver accurate-sounding mixes to your listeners. This makes these headphones a reliable companion for those who place value on quality and precision. Let’s take a look at everything we know about them so far.

As professional studio reference headphones, the HD 400 Pro headphones are designed for everyday monitoring, mixing, and mastering. Whether you’re working at home or in the studio, your mix should sound the same as when the listeners hear it. After all, it’s all about the mix, so your everyday reference headphones should be the HD 400 PRO if you value quality and precision above all else.
The Design
All of Sennheiser’s gear is solidly built, and I would expect the HD 400 Pro to be no different. It has a 10-foot coiled cable in a detachable design. An additional 6-foot straight cable is also included in the box for convenience. Using a screw-on adapter, you can connect your headphones to your mixing desk, audio interface, or any other audio device with a 1/4-inch (6.3mm) or 1/8-inch (3.5mm) output.
The Fit
Open back, over-the-ear headphones are generally perfectly comfortable and unobtrusive on your ears. They have a snug and comfortable feel without being too tight on your head. After long mixing or mastering sessions, the last thing you want is a migraine. The HD 400 PRO’s lightweight design helps avoid that. Its articulating earcups, velour earpads, and adjustable headband allow for adaptability and comfort to perfectly match the shape of your head.
If you wear glasses, these headphones shouldn’t tilt them in strange directions. Their excellent sound isolation system should kill any ambient noise in your listening environment as well.
The Sound
The open earcups mimic the soundstage found in high-end recording studios, recreating the optimal listening position. Rather than construing, these headphones ensure neutral transparency — the best foundation for mixing.
Featuring a wide frequency range, HD 400 PRO gives you clean, balanced, versatile sound. They were developed to be honest on all levels, especially when it comes to the lower end of the spectrum. With the angled 120ohm transducer design, you can achieve superior stereo imaging and reproduce the spatial sound of your mix with great clarity. This means what’s in your mix comes out as you intended.
Its highly efficient driver magnet provides clarity while its damping system manages ventilation. Professional users will appreciate the deeper bass this produces while also minimizing distortion that otherwise impacts sound quality. HD 400 PRO reference headphones reproduce analytical audio, making them perfect for everyday use.
Final Thoughts
With the HD 400 PRO, you can fine-tune your sound in a natural and accurate way. They feature an open-backed, over-ear design that delivers powerful, clear sound for every monitoring task, while effectively reducing ambient noise. These headphones offer outstanding comfort, courtesy of their lightweight design and soft velour ear cushions. A robust single-sided cable gives rise to tangle-free, unencumbered movement. You can use them to focus on your mix at home, in the studio, at live events, and more.
The Sennheiser HD 400 Pro Headphones provide an enjoyable listening experience and are currently available to order through Adorama for $249.
