Customer Review Summary
Introduction to the OLLO Audio R1 1.0
The OLLO Audio R1 1.0 is a set of over-ear, closed-back headphones released in December 2025, priced at £349. Designed and manufactured in Slovenia, these headphones aim to combine high build quality with a balanced acoustic performance. The use of premium materials such as American walnut wood for the earcups and stainless steel for the headband immediately sets these apart from typical offerings in this price bracket.
Design and Build Quality
At 386 grams, the OLLO Audio R1 1.0 strikes a balance between sturdiness and wearability. The closed-back design utilises earcups crafted from solid American walnut, which not only adds aesthetic appeal but likely contributes to acoustic properties by reducing unwanted resonance. The headband is built with stainless steel, wrapped in artificial leather for durability and comfort. This combination promises longevity and user comfort during extended listening sessions.
The ear pads are composed of acoustic foam covered with artificial leather, providing a snug yet soft fit. This construction contributes to effective noise isolation, a crucial factor for a closed-back model. The headphones come with a detachable, smooth two-metre cable terminating in a 3.5mm stereo mini jack, accompanied by a 6.3mm adapter. Installation is straightforward, facilitated by dual mini XLR connectors ensuring secure and reliable connections.
Sound Performance
The OLLO Audio R1 1.0 delivers a frequency response from 5 Hz to 22,000 Hz, covering both deep sub-bass and clear upper treble. Operating at an impedance of 32 Ohms, these headphones are compatible with most consumer audio devices without requiring a dedicated amplifier, though they can benefit from one for optimal output.
With a maximum sound pressure level of 110 dB, the R1 1.0 can reach high volume levels without distortion, making them suitable for a variety of listening environments. The headphones present a U-shaped sound signature, emphasising bass and treble with a recessed midrange, yet the bass is controlled rather than overblown. This balance favours detailed mid frequencies, crucial for vocal clarity and instrument separation, without sacrificing low-end impact.
Comfort and Practical Use
Comfort is a notable aspect of the R1 1.0. The combination of lightweight materials and high-quality padding ensures fatigue-free use over extended periods. The closed-back design naturally isolates ambient noise, which can be beneficial in noisy environments or for critical listening.
The detachable cable design adds to practical convenience, enabling easy replacement if damaged and reducing wear where cables are prone to break. The inclusion of a hard case protects the headphones during transport, maintaining their premium condition.
Conclusion
The OLLO Audio R1 1.0 headphones offer a compelling package with a focus on audio fidelity, build quality, and comfort. Their use of American walnut and stainless steel enhances both aesthetics and durability. Sonically, they provide a balanced, slightly U-shaped sound signature that avoids exaggerated bass, favouring an accurate and pleasant listening experience. These headphones should appeal to audiophiles seeking a quality closed-back model that performs well across genres and listening scenarios.
