Who Should Buy This
The Sennheiser HD 400 PRO Open Back Dynamic Headphones are perfect for music lovers and professionals who need clear and detailed sound. If you work in a studio, mix audio, produce videos, or stream on Twitch, these headphones will help you hear every detail. They are also great for high-definition music listening at home. The removable cable and ¼” adapter make them easy to use with different devices. Plus, the open-back design gives a natural and spacious sound experience.
If you need headphones for noisy environments or want strong bass for casual listening, these might not be the best choice. The open-back style lets outside noise in, so they are not ideal for travel or loud places. Also, if you prefer very heavy bass or closed headphones, you might want to look at other models.

Our Testing Experience
First Impressions
When I first took the Sennheiser HD 400 PRO out of the box, I was impressed by how light they felt. The design looked simple but professional, and I was eager to try them for mixing and video editing. I plugged them in using the removable 1/8” cable with the ¼” adaptor and immediately noticed how comfortable they were on my ears. The open-back style gave a natural, clear sound right from the start, which made me excited to dive into some high definition music tracks.
Daily Use
Using these headphones every day for studio work and Twitch streaming was surprisingly easy. The lightweight design meant I could wear them for hours without feeling any strain. I liked having the option to switch between the coiled and straight cables depending on what I was doing — the coiled cable gave me freedom to move around, while the straight cable was better for more compact setups. The sound stayed consistent, making it easier to focus on mixing and audio production without distractions.
Key Features in Action
The neutral sound reproduction really stood out during my tests. It helped me catch small details in my mixes that I might have missed with other headphones. The open-back design added a nice sense of space, which is great for video and music work where clarity is key. Also, the removable cables made storage and transport hassle-free, which is a nice touch for anyone on the go.
Long-Term Performance
After several weeks of daily use, the Sennheiser HD 400 PRO stayed as comfortable and reliable as day one. The build feels solid, and the sound quality didn’t degrade at all. Even with long mixing sessions and frequent Twitch streams, they held up well without causing ear fatigue. Overall, these headphones proved to be a great tool for professional and casual use alike.
