Wired Studio Headphones with Dual Jacks

The OneOdio A71 is a wired over-ear headphone built for studio monitoring, mixing and DJ use. It carries Hi-Res Audio certification and uses 40 mm dynamic drivers with a 32 ohm impedance. The package includes both a 3.5 mm and a 6.35 mm plug on a coiled cable that extends from 6.6 ft to 9.8 ft.

SharePort and Swivel Cups for Collaborative Work

A built-in SharePort lets a second pair of headphones plug directly into the A71 without splitters or extra cables. The earcups swivel 90 degrees so you can monitor with one ear while keeping the other free for conversation. A protective case and detachable cable are also supplied in the box.

Check Your Device Jacks

Verify that your audio source provides either a 3.5 mm or 6.35 mm output; no adapter is included beyond the two plugs already on the cable. The coiled lead stretches to 9.8 ft, so confirm that length suits your desk or booth layout. These are passive wired headphones with no battery or wireless function.

Questions about this item

Will the 40 mm drivers or ear cushions need replacement after heavy studio use?

The 40 mm dynamic drivers are built for long-term monitoring; the protein-leather ear cushions are detachable and can be swapped if they wear out.

What limits the A71 during an all-day mixing session?

The 80 ohm input impedance and 32 ohm driver rating mean output level depends on the source device; very low-power ports may run out of headroom first.

How much heat or noise do the headphones produce when worn continuously?

Passive noise isolation blocks external sound without active electronics, so the cups stay cool and add no self-noise during extended wear.
