"Absolutely LOVE the S4R 2021’s! A major leap forward from the first generation S4 models. More precise, well balanced, and extremely comfortable to work with for long hours. These are a game changer around the studio for sure."
MARKUS MANN![]()
"With these headphones, we had no leakage at all. That was brilliant. And surprisingly they're also suitable for mixing actually, which I thought is actually impossible with closed-back phones."
BERNHARD SCHMOLMÜLLER![]()
"My recordings sound better and more alive. Because of the closed construction I can use a larger dynamic range and the smallest details and nuances are perfectly audible. The S4R has become indispensable in my studio."

Sound isolation
We put a lot of effort into balancing isolation and final frequency response to deliver recording headphones that sound neutral and keep the click track from bleeding out. Watch Rok geek out on the game.

FREQUENTLY ASKED QUESTIONS
Since the S4R 1.1 have a similar frequency response to the S4X reference model, it will do an excellent job for preliminary mixing and producing. The closed cabinet has its flaws regarding the sound stage, though, so our recommendation for mixing and mastering lies with the S4X model.
