Handcrafted in the Slovenian Alps, the Ollo Audio R1 1.0 is the high-end headphone manufacturer's closed-back, over-ear model. Like all Ollo products, the R1 1.0 has been designed for use in the studio – with great wearability even over long periods, an impressive sound image, generous gain, and very robust build quality. These closed dynamic headphones are especially suited to life in the recording room, with a clear focus on blocking out external noise, as well as preventing sound leakage that might colour the recording itself: The manufacturer's specs give a measured external noise attenuation of -10dB, which is very impressive. As such, unwanted acoustic emissions are well below those of open constructions, even with loud signals like clicks.
Every part of the coherent concept behind the Ollo Audio R1 1.0 contributes to its powerful sound. It all begins with its high‑quality mechanical construction that – thanks to large over‑ear pads, swivel‑mounted earcups, and an adjustable headband – not only ensures optimal comfort, but is also key for sound quality and the aforementioned external isolation. At the R1's technical core are its dynamic 50mm drivers driven by neodymium magnets, with patented PU/PET composite diaphragms that deliver a frequency response of 5Hz to 22kHz. One interesting feature is the deliberate, albeit slight, attenuation of the midrange frequencies, which actually results in a more powerful overall sound, much like a loudness effect. With an impedance of just 32 ohms, the Ollo Audio R1 1.0 also delivers its loud, powerful sound when driven by low-voltage sources.
The Ollo Audio R1 1.0 stands out not only for its sound, but also for its striking design. The earcups are crafted from walnut, contrasting nicely with the pads finished in black synthetic leather. The headband is also a well-judged blend of steel and silicone, so the build is more than robust enough for day‑to‑day studio work; that said, with a weight of only 386g, they're comfortable long-term, too. Of course, nothing lasts forever, and as sustainability is a big part of Ollo Audio's concept, they've ensured that all key components can be replaced with a minimum of effort: The cable, ear pads, headband – even the drivers – are designed to be swapped out when needed. The dual‑sided cable, with a practical length of 2m, has sturdy mini‑XLR connectors and a 6.3mm adapter, so there'll be no unwanted connection issues. A carrying case for safe storage is also part of the package.
An emerging manufacturer from Slovenia, Ollo Audio specialises in crafting high-end studio headphones tailored for professional music production. Their range includes closed-back models for recording and open-back designs for mixing and mastering, each engineered with exceptionally linear frequency responses. Accompanied by custom calibration software, these headphones deliver precise, reliable results in studio environments. Ollo Audio places a strong emphasis on durability and sustainability, constructing their headphones from robust materials like wood and metal to combine accurate sound reproduction with a premium tactile experience.
Any producer or engineer who does regular sound recording work needs at least one pair of closed‑back headphones. The R1 1.0 is Ollo Audio's debut in the competitive premium mid-range, deliberately and confidently taking on the established manufacturers here. The most distinctive elements here are certainly the refined aesthetic and the outstanding comfort; however, this is all backed up by the unit's large drivers and low impedance, which reliably deliver high maximum levels. Another priceless feature in recording settings is the exemplary external isolation. At the same time, Ollo Audio has very deliberately commited to an adjusted frequency response that gives the otherwise linear sound profile a dip in the mids that really makes them a pleasure to work with. And if anything does ever go wrong, the sustainable serviceability of the device should give users of all kinds peace of mind.
