OLLO Audio manual


APPROVED BY RECORDING ARTISTS

When they're recording vocals or instruments it's important they hear their tone as it is. All the details must be preserved and nothing should be exaggerated. A well tuned recording headphones are an essential tool.

“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

HOW DO THEY SOUND?

Comparing frequency responses with other studio headphones market leaders.

RESEARCH AND DEVELOPMENT

PERFECTING THE SOUND IN A CLOSED BACK CABINET

LEARNING FROM OUR COMMUNITY

We took a look at the S4R 2018 model, made a list of features that were well accepted by the community, and also the list that we were even more interested in - the list of things we had to change.

SOUND ISOLATION & FREQUENCY RESPONSE

We put a lot of effort into balancing isolation and final frequency response to deliver near-perfect recording headphones. Watch Rok explaining 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.

We will open the option to upgrade your previous models to S4R once the preorders are over. You will be able to upgrade from the S4 or the S4R 1.0, or even crossgrade from the S4X model.
