OLLO AUDIO [X1 Pre-order Special Price: The Grand Price; Regular Price from Next Shipment] X1 (Auro Audio) (Open-back headphones) (Sound Engineer Headphones) (Mixing & Mastering)

Since its launch in 2024, the "X1" headphones have been very well received, and last year, in 2025, after celebrating its first anniversary, it achieved an unprecedented record of 1,000 units sold domestically in a single year for a monitor headphone product in its price range.

BAD MONITORING STEALS YOUR GRAMMY

Most studios do not have a truly flat frequency response, and the persistent modal dips and peaks cannot be equalized even with software. The X1 solves this problem with room independence and flat tuning, providing a monitoring environment comparable to the world's flattest-sounding studios in the simplest way possible.

●FLAT SOUND FROM LAPTOPS TO ANALOG CONSOLES
With the "X1," you don't need to adjust the acoustics of your room.
The "X1"'s individual calibration adapts to various devices without relying on plug-ins.

Individual calibration can be performed not only with the included USC II plugin, but also directly as EQ values ​​in hardware such as "RME Total Mix," "UA Console," "MOTU Control," "Neumann Monitor Mission," DSP-enabled audio interfaces, and even analog EQ strips.

● Individual Calibration Using AI Processing Every "X1" unit is individually tested and calibrated to correct deviations in frequency response due to materials and acoustic tolerances. The analytical power of AI allows for even more precise fine-tuning of the "X1".

● Stereo, Spiral, and Harman Target: The default calibration of the "X1" is optimized for stereo mixing, but a one-click switch to binaural mode allows for cross-checking spiral audio mixing and mixing using the popular Harman Target curve. (Available only with the USC II plugin)

●USC II specifications
Unit-Specific Calibration (USC) is the "final mile" to achieving a perfectly flat frequency response. Every unit in OLLO headphones is measured and highly quality-controlled. By measuring individual units, we can capture the sound quality deviations caused by the manufacturing tolerances of each individual unit. By performing calibration based on this data, we can achieve an incredibly low tolerance of approximately -1dB for the selected frequency target. This means that frequency characteristics that cannot be achieved through acoustic design alone can be corrected.

The included Unit-Specific Calibration II (USC II) contains a Realphones software plugin and a calibration data file generated using AI power. The plugin is available in AU, VST, and AAX formats for Mac/Win users, and a standalone version is also available. The calibration data file is in XPS format, allowing for manual export of precise EQ values ​​to third-party EQ plugins or DSP-enabled hardware (e.g., RME TotalMix, Neuro DSP, etc.). (e.g., RME TotalMix, Neumann Mission Control, UA Console, etc.)
