Flat out of the box...

...is the phrase reviewers coined for the S4X. Their neutral and honest sound signature was perfected in close R&D collaboration with professional mixing and mastering engineers.

We don't pretend to know flat better

Lab research showed massive inconsistencies in popular target curves. So we relied on renowned industry professionals instead and reverse-engineered their preferred EQ compensations as a base for the S4X's frequency response. S4X's sound signature was advised by the pros, not lab geeks. Intrigued? We offer 30 days trial on all purchases.

Amplifier independent

As mixing takes place in many different setups we went with 32 ohm impedance and made them compatible with pro level and laptop integrated amplifiers. Industry standard jack connectors make them a plug and play on just about any audio gear.

Benefits of individually measured pairs

With your headphones' measurements charts you will have a better understanding of what you're hearing and have an edge in mixing and mastering for best translation of your projects.

R&D LAB | how we approach sound signature

powerful acoustics

Acoustics in headphones are shaped with earpads and airflow resistors. The driver is only half of the final sound.

scientifically validated

We reverse engineered what professional consider flat and validated all data sets using state of the art frequency, impulse, THD and other measurements techniques.

built to last

S4X are made using aluminium, stainless steel, wood and minimal plastic components. If you take good care of them, they will last. For moments when life happens, we offer any and all spare parts.
