FLAT SOUND OUT OF THE BOX

The X2 is OLLO Audio's new flagship open-back headphone for producing, mixing and mastering. Few rooms are truly flat – even in the sweet spot, room modes create peaks and dips no plugin can fully fix. The X2 takes the room out of the equation, giving you a neutral, accurate reference wherever you work.

Level 1 – Acoustics

The X2 is tuned neutral using acoustics alone. Plug it in and it's ready for serious work – no software required.

Level 2 – Unit-Specific Calibration (included)

Every X2 is measured individually in quality control. Its unit-specific calibration (USC) file corrects the small deviations acoustics can't, bringing the response to within roughly ±1 dB of target – tighter than generic headphone-correction software can achieve.

Your calibration, any device – no lock-in

The USC file contains plain, unencrypted EQ data. No subscription, no locked ecosystem. Use it in the included USC plugin, Realphones, SoundID (custom target), or any EQ plugin – or dial it straight into DSP hardware such as RME TotalMix, UA Console, MOTU, Neumann MT48 or Metric Halo. A printed calibration datasheet is included in the box, so you can recreate your correction in any guest studio.
