What it is and who it's for

The OneOdio Monitor 80 A-AA11-01 is an open-back wired headset built for studio monitoring, critical listening and gaming. Its 250 ohm impedance demands a dedicated headphone amplifier or audio interface to reach proper volume and dynamics. Casual listeners plugging straight into a laptop or phone will find the output too quiet.

The specification that decides fit

Impedance is 250 ohm, so the headset requires a source capable of driving high-impedance loads. Frequency response spans 10 Hz to 40 kHz and the headphones are Hi-Res Audio certified. Two detachable cables are supplied: a 3.5 mm mini-phone lead and a 6.35 mm stereo adapter, both 11.48 ft long.

Thermals, noise and power

Open-back construction lets air circulate through the aluminium honeycomb housing, keeping the ear cups cool during long sessions. Velour pads and an adjustable headband distribute weight evenly without clamping pressure. Passive operation means zero self-noise and no battery to charge; the only power drawn is the signal from your amplifier.

Questions about this item

How does 250 ohm impedance affect everyday use?

The 250 ohm rating means the Monitor 80 needs a dedicated headphone amplifier or audio interface to reach full volume and dynamic range; a phone or laptop jack alone will sound quiet.

What connectors do the detachable cables use?

One cable ends in a 3.5 mm mini-phone plug and the other in a 6.35 mm stereo plug, so you can connect directly to portable gear or studio equipment without extra adapters.

How much space does the 11.48 ft cable need on a desk?

At 11.48 ft the cable reaches across a typical workstation with slack for movement, and because it detaches you can replace it with a shorter run if space is tight.
