OLLO Audio has launched the X2 for mixing and audio production. The open-back, over-ear studio reference headphones use 50mm dynamic neodymium drivers and are available to order through the company's website. Shipping is scheduled to begin on 7 December 2026, with the first production batch limited to 100 units.
Each pair is measured individually, with its calibration data supplied in an open format. The X2 includes the USC calibration plugin, while the data can also be used with Realphones, Sonarworks, Waves Nx or DSP-enabled audio interfaces.
The driver membrane uses beryllium-coated PET (PVD) and polyurethane. Specified frequency response is 8Hz to 22kHz using a 1/3-octave sweep, ±1dB. Impedance is specified at 32 ohms, with sensitivity rated at 108dB SPL at 0dBu input.
The headphones are hand-made in Slovenia, where OLLO Audio is based. Their housings are made from American walnut, while the headband combines stainless steel and silicone. The ear pads use acoustic foam with perforated artificial leather and velour. A user-detachable cable connects via XLR connectors.
The X2 is designed to be serviced through replaceable components. Replacement parts are available for the headband, ear pads, cable, drivers and wooden housing. The headphones carry a five-year limited warranty.
