OneOdio A70 wireless over-ear headphones, Bluetooth 5.2, 72-hour playback

For musicians, audio engineers and listeners who want the choice of wireless listening or a wired connection, the OneOdio A70 brings both options together in a foldable, over-ear design. Its Bluetooth 5.2 connection suits everyday listening, while the supplied audio cables let you connect to a mixer or other audio equipment.

A 40 mm dynamic driver and sound-isolating earcups make the A70 a practical pick for listening to music, working with audio or taking calls. Blue finish and foldable earcups round out a design that can move between home listening and travel.

Best use cases

Use the A70 wirelessly with a Bluetooth-enabled device when you want to listen without an audio cable. For a wired setup, connect through the 3.5 mm or 6.35 mm jack, this gives musicians and audio engineers a direct way to use the headphones with compatible instruments, amplifiers or mixers. The two connection points and supplied cables also support sharing stereo music from one device at the same time.

For longer listening sessions, the padded over-ear cups sit around the ears, while the foldable construction makes the headphones easier to carry between home, the studio and a trip. The built-in microphone supports calls, and CVC8.0 call noise cancellation is designed to help keep your voice clear. Bluetooth range is listed at 10 metres, so you can listen without staying beside your connected device.

Why it’s worth it

The key advantage is choice: keep listening wirelessly for day-to-day convenience, or switch to a cable when your setup calls for a connection to audio equipment. That flexibility makes the A70 more adaptable than a wired-only pair for listeners moving between music, calls and music-making. Bluetooth 5.2 and up to 72 hours of playback support extended wireless use, while the included microphone adds call functionality without changing headphones.

The 40 mm driver covers a 20 Hz–20,000 Hz frequency range, with sound described as having a natural mid and treble range and tight, powerful bass. For a practical scenario, use Bluetooth for a long listening session, then connect by cable to a mixer for audio work. A 90° reversible earcup design and foldable build add useful handling options when carrying or wearing the headphones around your neck.

Is it worth it?

It’s a good fit if you want one pair for wireless listening and wired audio setups, rather than choosing a set designed for only one connection style. The combination of Bluetooth 5.2, long stated playback time, over-ear cushioning and 3.5 mm and 6.35 mm connections serves music listeners as well as musicians who need to plug into compatible audio equipment. Choose the OneOdio A70 for that mix of listening flexibility and practical studio connections.
