They were plagued by some of the common stumbles of first-generation earbuds with no cable between them — connection dropouts, audio delay when watching video, and so-so battery life — and the promised noise cancellation failed to measure up to Sony’s popular 1000X headphone series. But Sony is back.
Sony has brought over the clever Quick Attention mode from its 1000X headphones: resting your finger over the left earbud temporarily activates ambient audio for however long you hold it there; once you let go, the noise cancelation comes right back.
This means you can use either Sony M3 earbud by itself for listening to audio or making voice calls while the other is charging inside the case.
