Open-Back Studio Headphones for Mixing

The OneOdio Monitor 80 is a wired open-back headphone built for mastering, mixing and tracking. Its 40mm drivers deliver a 10Hz-40KHz frequency response with Hi-Res audio certification. The 250 ohm nominal impedance requires a dedicated amplifier to reach proper listening levels.

Sustained Studio Session Comfort

Velour ear pads and an adjustable headband distribute weight without pressure during long mixing sessions. The open-back architecture reduces distortion and provides accurate, full-range sound reproduction. A stainless-steel hinge rated for 100000 rotations maintains structural integrity over extended daily use.

Amplifier and Cable Compatibility Check

Verify your audio interface or headphone amplifier can drive 250 ohm loads before ordering. The package includes a 3.5mm to 3.5mm cable and a 3.5mm to 6.3mm cable, so no separate adapter is needed. Ensure your source device has a compatible 3.5mm or 6.3mm output jack.

Questions about this item

How much heat or noise do the open-back Monitor 80 headphones generate during long studio sessions?

The open-back design vents air naturally, so the cups stay cool and add no electronic noise; only the audio signal is heard.

What amplifier or audio interface must I already own to drive the 250-ohm Monitor 80 properly?

A dedicated headphone amp or interface with enough voltage swing for 250 ohms is required; phones and laptops alone will not reach adequate volume.

Will the Monitor 80's 3.5 mm and 6.3 mm cables work with my older mixer that only has quarter-inch jacks?

Yes, the included 3.5 mm-to-6.3 mm cable plugs directly into quarter-inch outputs without any separate adapter.
