Our Verdict

Anker Soundcore Space A40 Truly Wireless

Nothing Ear (3a)

For most people, the Anker Soundcore Space A40 Truly Wireless are a better pair of affordable earbuds than the Nothing Ear (3a). That's largely due to their superior ANC and longer battery life. But the Anker also have an auto-off timer to conserve battery, and their case supports wireless charging. That said, the Nothing are slightly more stable in-ear and come with a detailed parametric EQ in the companion app, so you can really dial in your preferred sound. The Nothing's mic system also does a better job separating your voice from any noise around you, but your voice will still sound harsh to whoever you're speaking to.
