OneOdio A70 Bluetooth Over-Ear Headphones, 72-Hour Playtime, 3.5/6.35 mm Jacks

What you’ll notice day to day

Bluetooth listening and a wired option make the OneOdio A70 useful for different parts of your routine. Use them wirelessly for music, calls, or a commute, then connect by cable to a compatible audio device for monitoring, mixing, or playing an instrument through an amp. The 40 mm drivers are designed for stereo sound with powerful bass and clear detail, while the over-ear fit and soft memory cotton earpads support extended listening.

With up to 72 hours of playtime in wireless mode, the A70 can keep up with long stretches away from a charging routine. Switch to a wired connection when you want to listen without relying on battery power.

What matters most

The dual-mode design is the main advantage over headphones built only for wireless listening. The A70 includes a 3.5 mm-to-3.5 mm cable and a coiled cable with 3.5 mm and 6.35 mm plugs, so you can connect with compatible laptops, desktops, tablets, and music production equipment. The jack-lock design helps keep the wired plug securely connected during use. For electric guitar, connect through an amp, the headphones are not a direct connection for an electric guitar.

For everyday Bluetooth use, the headphones support Bluetooth 5.2 and have an inline microphone on the 3.5 mm cable for calls. When listening with another person, the sharing function lets you connect an additional pair of headphones through the audio cable. This makes the A70 a practical fit for sharing music or video audio as well as switching between personal listening and studio-style setups.

Customers often highlight sound clarity, comfortable earpads, and battery life. Feedback on connectivity and reliability is mixed, so experiences with those aspects vary. These impressions can help set expectations, while the wired mode offers another way to connect for listening and audio work.

Everyday use

Use Bluetooth for a phone, tablet, or computer when you want to move around without a cable. At a desk or in a music setup, choose the connection that matches the device’s audio jack: the included cables provide 3.5 mm and 6.35 mm options. The 3.5 mm cable is 3.9 ft, and the coiled cable extends from 4.9 ft to 9.8 ft. The cables also make it easy to shift between compatible devices without relying on a wireless connection.

If your priority is a wireless-only set of headphones, a simpler design may suit that preference. The A70 is better suited to someone who values both Bluetooth convenience and the option to plug into studio, DJ, or instrument equipment.

Before you decide

Can I use the A70 with a phone over Bluetooth? Yes. It connects wirelessly to Bluetooth-enabled devices, including smartphones, tablets, and computers.

Can I plug an electric guitar directly into the headphones? An electric guitar requires an amp as the connection between the instrument and the headphones. Other guitars may not work directly with the headphones.

Can two people listen at the same time? Yes. Connect the main headphones to the audio source by Bluetooth or cable, then use the audio-sharing connection to link another pair of headphones.

Final verdict

The OneOdio A70 suits listeners who want one pair for everyday wireless audio and wired music work. Its 72-hour wireless playtime, two cable options, and support for shared listening make it especially useful when your setup moves between a phone, computer, and compatible audio equipment.
