OLLO Audio R1 1.0 is a closed-back studio headphone built specifically for recording applications. It offers strong isolation, minimal leakage into microphones, and an ergonomic construction made from premium natural materials for long, comfortable studio sessions.
The distinctive U-shaped frequency response, with emphasis on bass and high frequencies, helps musicians stay in the groove while maintaining clear perception of melodic details. Sound isolation of up to –10 dB reduces environmental noise and significantly minimizes click-track or backing-track leakage.
Designed for extended use, the R1 features large 100/60 mm ear-pads that fully surround the ear, a self-adjusting headband, and rotating ear-cups for even pressure distribution. The construction combines American walnut, stainless steel with silicone coating, and high-quality artificial leather. All components are user-replaceable using common tools.
