OLLO Audio S4X 1.3 Calibrated (Open)

Unit Specific Calibration file and plug-in are included with your purchase. With USC they are calibrated to ~1 dB tolerance to the respective target curve (spatial or stereo). The plug-in runs on PC and Mac with AU or VST3 supported DAW (Cubase, Reaper, Studio One, Ableton, Nuendo, Mixbus, etc.). You can also integrate USC directly with room emulations by Waves Audio and head tracking or run it in a daisy-chain. Available studios include Abbey Road, Ocean Way, Germano-Hit Factory and CLA Mix LA.

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.

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 aluminum.
