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. The new 1.3 version now includes USC calibration to push that even further.
Benefits of individually calibrated pairs
With perfectly calibrated headphones you'll have an edge in mixing and mastering for best translation of your projects.
You can expand your monitoring options with the Waves NX room emulations from Abbey Road, Ocean Way, Germano or CLA Mix L.A..
TRUSTED BY PROFESSIONALS
★★★★★A professional sound design buddy recommended the S4X’s after I said I was saving up for Audeze’s.
He said they were equal in sound quality with a more moderate price and a lot lighter.
I’m already trusting them more than my main monitors for final mixdown and mastering duties…and than is saying something.

★★★★★"I love the depth and clarity I get in my mixes with the S4x. Especially in the kick and snare which is often so hard to get a punch in headphones that will translate to a speaker. But more then anything, they really make it fun to listen to music for a long period of time!"
John Escobar
Independent Producer/engineer, Professor - Berklee College Of Music
★★★★★"I never used headphones to make my mixes, except to check for any noise that was causing me problems. Thanks to their excellent work I can mix without compromise even in the living room. Ollo Audio puts in the reference headphones the same care that I put in my work. "

★★★★★"The separation between the instruments, the dynamics and stereo image are perfect to be comfortable mixing with them.
I was amazed by the S4. But I am floored by the new S4X reference headphones.
Just amazing!"

MATCHED SPEAKERS
The speakers are matched in the lab in 100-unit batches using an automated process that has been perfected over the last 5 years of research. This process includes frequency domain analysis, which is more complete than just SPL analysis.
ACOUSTICS
Front of the speaker cavity is sealed off from the back of the speaker. In principal it's similar to a closed guitar or bass speaker cabinet. This design produces a smoother frequency response and separation of low-end to the mid frequencies.
SILICONE CABLE
The cable is designed with an OFC core that delivers the original signal without harmonic or other audible distortion. The silicone finish makes it less microphonic than braided cables and easier to handle.
CUSTOM EARPADS
The earpads are directly responsible for the acoustic coupling impedance between the headphones and your ears and hence greatly affect the frequency response. They are a hybrid of velour padding on the area that touches your skin and artificial leather. This provides a smooth low-end reproduction with controlled flow resistance through velour coupling.
SELF-ADJUSTING HEADBAND
The headband is made of stainless steel and is designed to withstand heavy usage. If necessary it can be replaced using home tools.
BUILT TO LAST
These are not made out of plastic. Headband is made out of stainless steel, wooden cups are CNC machined American walnut and the backplates are aluminium.
Studio reference class, open back, dynamic headphones with flat frequency response and USC calibration, made in the EU.

We believe in fair pricing all year long.
Free beats, gigs and mixes are all disrescpectful and are killing the industry. Everyone should be paid fairly and accordingly. So we do not offer discounts per se (not even on Black Friday and Cyber Monday) as we don't support that mentality.
We do lower the price when there is a good reason to do so. And we have three!
1. B STOCK UNITS
B stock items are sonically exactly the same as A stock but with minor cosmetic imperfections. These are brand new, unused units. Limited offer to when such units are available!
2. OFFER FOR STUDENTS
We’re aware that being at the beginning of your career can be hard. We have an offer to support all the audio-related students and teachers with a 25% discount on our headphones. To get this offer, please reach out to us with your student or teacher ID via this form, so we can verify eligibility and grant you a student status with us.
3. ENDORSEMENT PROGRAM
Our community is at the heart of everything we do. Engineers, creators and artists participate in the process of developing all of our products. If you work as a full-time audio engineer, musician, or in a similar audio-related profession and share the passion for pro-audio, you can apply to join. The endorsement community is the cornerstone for our R&D team. We take their feedback very seriously. Interested? You can apply here.

S4X 1.3 version is acoustically identical to the 1.2 version but with the USC calibration plugin included. This improves their flat frequency response from ~2dB down to ~1dB tolerance using DSP.
S4X 1.0 has female jacks mounted on the panel with a straight down cable position. S4X 1.1 has an angled cable position that enables front and back cable position depending on the use case. They are “flippable”. S4X 1.2 is the same as 1.1 but with embedded connectors for greater durability.
Regarding S4X vs S5X tuning, the S4X are slightly darker sounding and warm. They represent how a common room will sound. That, together with acoustics properties, makes them a staple in over 10,000 studios worldwide for mixing and producing in stereo. The S5X are specifically tuned for spatial audio mixing with a brighter character that helps with 360 positioning and movements of 3D binauralised audio (e.g., Dolby Atmos). Both are tuned flat for their purpose. It’s not one target frequency response curve that fits all use cases.
Regarding S4X vs S4R tuning, the S4X is more laid back in comparison to S4R tuning that is made with clarity in mind. That is to deliver accurate monitoring for recording and podcasting sessions. Mids forward tuning is welcomed in monitoring for details and dynamics. Both of these are crucial when you’re recording instruments or vocals at the highest level.
