STATEMENTS
“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.”
- DRIES GEUSENS
FREQUENTLY ASKED QUESTIONS
Can the new S4R 1.1 be used for mixing?
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.
