* with the S4X model
"My mixes are very immersive, spacious and full of emotion. The HPS S4 respect all of the depth, width, air, tight bass, space and detail that I work so hard to create in a mix. Excellent reference headphones for mixing and mastering. Job well done!"
ADAM MOSELEY - U2, Rush, Beck, Genesis, Roxette, The Cure etc.![ADAM MOSELEY | OLLO Audio ambassador]()
“The OLLO Audio PLAY2ME system is my favorite headphone monitoring system. The headphones sound amazing and with the silent subwoofer I can feel every bit of the low end without blasting it on the mains. I use it on every mix.”
GARY NOBLE - Amy Winehouse, Jessie J, James Arthur, Joss Stone etc![OLLO Audio Ambassador Gary Noble]()
"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!"WILLIAM ROBERTSON - Mick Jagger, Nicki Minaj, Will.I.Am.![WILLIAM ROBERTSON OLLO Audio ambassador]()
USE CASE:
"Owning a studio is not a must anymore. You can rent when you really need it and you can polish 90% or more just using headphones and basic home setup."
USE CASE:
"Because I do tour a lot, my workflow needs to be flexible enough to allow me to work mobile while still making the same critical listening decisions I would make at a world-class recording studio."
TRY BEFORE YOU DECIDE
We know it's difficult to make an educated decision based on tech specs and reviews. The only true way to know if they are for you is to try them out.
OLLO vs. Sennheiser vs. Audeze vs. AKG vs. Beyerdynamics vs. Audio Technica
We measured and compare the frequency responses of the main mixing headphones on the market. Measurements were made using G.R.A.S 45CC using IEC 60318-1 ear simulator and Dewesoft AD conversion Sirius system.
