Linear monitoring and mixing headphones
The Ollo Audio X1 1.0 is a high-grade, open-back, over-ear headphone designed for precise monitoring duties in studio environments, with a focus on editing, mixing, and mastering applications. Its linear sound signature provides a natural and detailed image, allowing precise judgement of levels, EQ, and spatial placement, supported by its open-back design and high-performance components. The X1 ships with the USC-II calibration system, a software suite that can be used either as a plug-in within a DAW or applied system-wide. With meticulous accuracy, the software's configuration file is based on measurements specific to each individual set of headphones; it applies subtle EQ correction to further refine the frequency response, while also offering optional listening profiles such as studio, FOH, and car environments, as well as alternative target curves and a binaural mode. Each X1 is individually measured during production in Ollo's facility in Slovenia, ensuring consistent performance from one handmade unit to another.

Engineered for accuracy
The Ollo Audio X1 1.0 is built around carefully selected components that contribute directly to its neutral and balanced sound. Its 50mm dynamic drivers are powered by neodymium magnets and paired with a patented PU/PET composite diaphragm, covering a frequency range of 5Hz to 22kHz. The open-back construction plays a key role in its performance, allowing a more natural and uncompressed sound image, with a clear sense of space and depth. The drivers are slightly angled within the earcups, contributing to a more realistic stereo field and improved localisation of individual elements within a mix. Featuring a low impedance of 32 ohms and a sensitivity of 101dB (SPL), the X1 can be driven effectively by a wide range of sources, from professional interfaces to laptops and smartphones, without requiring dedicated amplification.

A reliable reference tool
The Ollo Audio X1 1.0 is aimed at producers, mix engineers, and sound technicians who require a dependable reference solution for critical listening and mixing tasks, particularly in environments where acoustics are less than ideal. Its neutral frequency response and controlled low distortion ensure a consistent and transparent audio image, allowing professionals to assess balance and dynamics – and make decisions – with confidence. The USC-II calibration system uses a measurement file specific to each specific unit to apply subtle corrective EQ, while the accompanying software also offers optional listening environments, target curves such as the Harman profile, and a binaural mode. These tools support editing, mixing, and mastering workflows where accuracy takes precedence over enhancement. The X1 may also appeal to experienced listeners seeking an uncoloured and natural reproduction.
