Studio Headphones for Mixing and Mastering
The OneOdio Monitor 80 open-back headphones are built for studio tasks such as mixing, mastering and tracking. Their Hi-Res audio certification signals accurate reproduction for critical listening. The 250 ohm nominal impedance means they require a dedicated amplifier to reach proper volume and dynamics. They are not suited for direct connection to phones or laptops without an amp.
Aluminium Honeycomb Housing and Detachable Cables
The ear cups use an aluminium honeycomb structure that protects the high-precision etched diaphragms while keeping the open-back acoustic design. This construction reduces distortion and supports a neutral frequency response. Two detachable cables are included: a standard 3.5 mm audio cable and a 1/4 inch stereo adapter cable, so no separate adapter is needed for professional interfaces.
Velour Pads and Adjustable Headband for Long
Soft velour ear pads and an adjustable headband distribute weight evenly and allow airflow during extended use. Buyers who need closed-back isolation for recording or commuting should look elsewhere, as the open-back design leaks sound both ways. Verify that your audio interface or headphone amplifier can drive 250 ohm loads before ordering.

Questions about this item
What does the 250 ohm impedance mean for connecting these headphones to a phone or computer?
The 250 ohm nominal impedance requires a dedicated headphone amplifier; plugging them directly into a phone or computer will not provide enough drive for proper volume and sound quality.
Which cable ends are included for different audio jacks?
The package includes a detachable 3.5 mm audio cable and a 1/4 inch stereo adapter cable so you can connect to both portable devices and professional interfaces without extra adapters.
How do the detachable cables attach and what is the common mistake?
The cables plug into the ear-cup jack with a twist-lock mechanism; the step users often miss is fully rotating the connector until it clicks, otherwise the signal cuts out intermittently.
