Anker unveils Soundcore Sleep Earbuds 4 Pro with snore-masking and OLED charging case

Anker has unveiled the Soundcore Sleep Earbuds 4 Pro, wireless earbuds built primarily for sleep. The device is designed to mask a partner's snoring, track the wearer's heart rate and sleep patterns, and play both calming sleep sounds and regular music. Overnight statistics are stored and can be reviewed on the earbuds' charging case, removing the need to open a phone to check sleep data.

The charging case includes a built-in OLED screen that displays sleep metrics and allows the user to set an alarm without a smartphone. Anker says it has improved the earbuds' fit to make them more comfortable for side sleepers, addressing a common issue for in-ear sleep devices.

The launch reflects Anker's move deeper into health-focused consumer audio, combining noise masking with biometric monitoring in a single wearable. The Soundcore Sleep Earbuds 4 Pro will cost $350 and are scheduled to go on sale in November.
