Unit Specific Calibration
is a calibration file made at OLLO R&D lab for every individual unit and can be installed with OLLo USC plugin or with the Waves NX product line. All S-series headphones are within 2dB tolerance of their target curve and with USC and Waves NX plugin they are tuned flat to 1dB tolerance.
You can now mix on headphones with full acoustics properties of the Abbey Road, CLA, Ocean Way or Germano studios with perfectly calibrated pair of headphones.
The S5X are specifically tuned
to translate spatial audio between speakers and headphones playback - binaural downmix. Their sound field is acoustically designed to provide a neutral base for the HRTF virtualisation of spatial audio formats in binaural mode or virtual room emulations. With a full 360 degrees of accurately spatialised positions and movements the translation of your mix between speakers and headphones is always spot on. The target curve for these headphones was developed by capturing a certified Dolby Atmos studio and human A/B testing.
The S4X are a staple
in over 10.000 professional studios worldwide. They are designed to deliver honest representation and translation of stereo mixes to any playback system. Their target curve was advised by our ambassadors rather than our lab geeks. Intrigued?
The S4R closed back
are based on the same chassis and sound signature design of the S4X series. With a slightly "mids forward" response, they're an incredible tool for all recording artists, podcasters, singers and producers who care about the details. Passive sound isolation keeps the click track bleed at a minimum but also helps to quiet your awesome roommate.
“After listening and mixing using the S4X headphones for 2 day’s, I finally realized that I could mix using these headphones alone!Using the S4X headphones pretty much has eliminated the need to do the "car check" for me. These headphones are flat and revealing as well as comfortable for long term use. I highly recommend them!!”
"The Ollo S4 X has completely revolutionized the way I listen to the sonic arrangement of a song. It’s like having a sonic microscope. The level of detail and depth they get is astonishing."
"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!"
"These are the best sounding headphones I’ve ever heard… At least to my ears… Same sort of way that Alan Sides’ main monitoring systems at the Oceanway studios always just felt like an extension of my ears... as do these sexy sounding (and looking) ear pillows."
"Best headphones for accuracy and clarity."
"The HPS S4 respects all of the depth, width, air, tight bass, space and detail that I work so hard to create in a mix. I’ve compared them with the leading competitors and OLLO win! Excellent reference headphones for mixing and mastering. Switching between the headphones and my speakers is effortless. And they are really light in weight and comfortable for long periods of use .... and they look cool too! Job well done!"
"These are my favorite headphones. They sound great and are very comfortable. I’m able to use them for long hours without listening fatigue or discomfort. They come in “closed back” for recording and “open back” for mixing duties."
"These headphones feel like you're listening to speakers. For an engineer, and a mixer, to have that same kind of feeling like they're sitting in front of their favourite pair of monitors, is priceless."
“I love my S4X reference headphones: they sound fantastic, are reliable and trustworthy, sit comfortably on my head and around my ears, don't give me ear-fatigue and don't press my ear onto the glasses allowing for continued and comfortable use.”
