Anker put a display on the case of its new sleepbuds

I hope the tracking is better than it was on previous Anker sleepbuds. | Image: Anker Anker just announced its new Soundcore Sleep Earbuds 4 and 4 Pro for side-sleepers. They include the same audio masking tech found on last year's A30 sleepbuds ( that can really silent a snoring partner ) only now with longer battery life and improved ANC to help silent other noises in the environment.
