OneOdio A71 Wired Over-Ear Studio Headphones with 40 mm Drivers

Monitor a mix, practice with an instrument, or cue tracks for a DJ set with the OneOdio A71 wired headphones. Their over-ear design and padded cushions are made for extended listening sessions. A dual-plug cable supports common 3.5 mm and 6.35 mm headphone jacks. Swiveling earcups also make single-ear monitoring practical.

On-body feel

The over-ear earcups have soft padding, while the adjustable headband lets you set the fit for your listening position. When you need to keep one ear free to follow a conversation or another sound source, rotate an earcup for single-sided monitoring. Both earcups swivel, and the headphones fold inward for a more compact form between sessions.

Buyers often highlight the clear sound and soft feel around the ears. Feedback on fit is mixed: some appreciate the full over-ear coverage, while others find the fit snug. Reports on durability also vary, so these impressions are best treated as individual experiences rather than a promise of how every pair will hold up.

What you’ll notice day to day

The A71 is designed for wired listening in studio and music-making settings. Its 40 mm dynamic drivers and stated frequency response of 20 Hz–40 kHz suit monitoring, mixing, and listening for detail across a track. The 32-ohm impedance and 110 dB ± 3 dB sensitivity are useful reference points when choosing headphones for your audio setup.

The dual-duty cable has 3.5 mm and 6.35 mm plugs, so you can connect to gear with either jack size without relying on a separate adapter. That makes it a straightforward fit for compatible computers, mixers, keyboards, and other music equipment. For a practical session, connect to a mixer or computer for playback, then swivel one earcup when you need to hear the room while monitoring. A separate audio-sharing port lets you connect another pair to share music or video.
