Anker put a display on the case of its new sleepbuds

Anker released the Soundcore Sleep Earbuds 4 and 4 Pro, which use the same audio-masking technology that silences snoring and now offer longer battery life and enhanced ANC. The buds have a 20% smaller contact area than the A30, reducing pressure for side-sleepers. Both models ship with wireless-charging cases, and the 4 Pro case includes a display.
