Customer Review Summary
Introduction to the OneOdio Monitor 80
The OneOdio Monitor 80 headphones arrived in September 2023, targeting musicians and audio professionals in need of affordable, open-back monitoring solutions. Priced at £75, these headphones claim to deliver clear, neutral sound suitable for a range of studio applications including mixing and mastering.
Design and Build Quality
The Monitor 80 features an over-ear, open-back design with circumaural ear pads made of velour, offering breathability for extended use. Despite the lightweight plastic construction keeping the weight at 269 grams, the build maintains a solid feel.
Cable management includes two detachable cables, a 1.2-metre mini-jack cable with microphone and button, and a longer 3-metre spiral cable terminating in 6.35 mm and 3.5 mm connectors, increasing flexibility for both studio and casual use. The headphone’s sound emerges from a single cable side, simplifying placement and reducing cable tangling.
One area noted for potential improvement is the fit; the earcups have a somewhat loose hold, especially on smaller head sizes, which may affect the isolation and comfort for certain users over long sessions.
Technical Specifications and Audio Performance
- Driver Size: 40 mm Neodymium dynamic transducers
- Impedance: 250 Ohms, requiring amplification for optimal performance
- Frequency Response: 10 Hz to 40,000 Hz, wide range covering both sub-bass and extended treble
- Maximum SPL: 94 dB
- Power Handling: 1600 mW maximum, 30 mW rated power
- Distortion Factor: Less than 1% at 1 kHz and 100 dB SPL
The extended frequency range confirms the Monitor 80’s capability to reveal fine audio details and high-frequency content beyond the audible spectrum. The high impedance setting implies these headphones are best suited with powered studio equipment for optimal volume and sound clarity.
Sound character is distinctly neutral, favouring accuracy over coloured or bass-heavy profiles. This neutrality makes the Monitor 80 versatile across sound sources and genres. Users have praised the headphones for their sharp and clear soundstage, highlighting their suitability for home studios, including usage during the mastering stage.
Comfort and Usability
Comfort is a key consideration for extended mixing or editing sessions. The interchangeable velour ear pads contribute to breathability and reduced ear fatigue. However, the looseness of the headband fit might require adjustment or modification for smaller heads to ensure consistent placement.
The relatively low maximum sound pressure level of 94 dB reduces the risk of hearing fatigue during prolonged usage, though professional monitoring at higher gain levels may require volume control attention.
Accessories and Packaging
Included with the headphones is a hard case, providing protection for transport and storage. This addition enhances the product’s value, especially for users traveling between studio and live setups.
The interchangeable cables cover a good range of professional connectivity options, including a standard 6.35 mm plug for studio interfaces and a mini-jack for everyday devices.
Summary and Verdict
The OneOdio Monitor 80 headphones deliver a commendable balance of sound clarity, build quality and accessory inclusions at a competitive price point of £75. Their neutral sound signature and wide frequency response make them a strong choice for home studio monitoring and mixing tasks.
While the fit may require personal adjustment for smaller heads, the solid construction and thoughtful cable options contribute to a positive user experience. These headphones suit users who prioritize sound accuracy and comfort in a budget-friendly package.
