Mix & mastering engineer | Phono Studios is a professional online audio mix and mastering studio based in Berlin
"I've tried a lot of studio headphones over the years, but was never quite satisfied until I got my hands on these. I'm very impressed with how great the S4R sound straight out of the box. I've already had the pleasure of mixing a couple of projects on these, which translated great to both my studio and big club sound-systems. I particularly like the presence of the bass, which is important for me since a lot of the music I mix contains a lot of bass frequencies. Big thanks for the endorsement!"
