Ollo Audio

OLLO Audio is a Slovenian headphone brand founded in 2015 by Rok Gulič, who developed the concept from his own experiments in tactile transducers and headphone-based studio monitoring. The company grew out of a hands-on, garage-style start and is still closely associated with that founder-led, engineering-first origin story.

Its core focus is studio headphones for mixing engineers and recording artists, rather than a broad hi-fi catalog. OLLO’s lineup has centered on over-ear monitoring headphones, with an emphasis on hand-built construction, replaceable parts, and a durable, repairable design philosophy. It is not known for amplifiers, speakers, turntables, DACs, or cables.

In the market, OLLO sits in a niche boutique position: premium in intent, but not a mass-market high-end hi-fi label. Its appeal is strongest among professional and enthusiast buyers who value neutral tuning, longevity, and practical serviceability over brand prestige or lifestyle marketing. That makes it more of a specialist studio-audio brand than a traditional home-audio heavyweight.
