Wired Over-Ear Studio Headphones

The OneOdio A71D is a wired over-ear headphone built for studio monitoring, DJing, recording, and podcasting. It uses 40 mm drivers with a 32 Ω impedance and a sensitivity of 110 dB. The foldable frame and 90° swivelling ear cups support single-ear monitoring and easy transport.

32 Ω Impedance for Wide Device Compatibility

The 32 Ω impedance allows the headphones to be driven directly by laptops, audio interfaces, mixers, amplifiers, guitars, and keyboards without a dedicated headphone amplifier. A 3.5 mm to 6.35 mm adapter is included for professional 6.35 mm jacks.

Passive Isolation with No Power Required

Passive noise isolation reduces ambient sound without batteries or active circuitry. The non-detachable 2.2 m cable connects via 3.5 mm plug, and the 32 Ω load draws minimal current from the source device. No power supply or charging is needed.
