Anker’s Sleep Earbuds get a display and sleep-tracking upgrade
Anker unveiled Soundcore Sleep Earbuds 4 and 4 Pro for side-sleepers, boosting battery life and ANC, with an OLED display on the SleepHub case for the 4 Pro to swipe through soundscapes, check sleep stats, and set alarms. The 4 Pro adds an in-ear PPG sensor and Soundcore’s BioSync adaptive soothing audio to help with sleep. The Earbuds 4 launch in October for $229.99 / £199.99 (white/blue, pink later); the 4 Pro arrives in November for $349.99 / £299.99. Both cases support wireless charging, but the Pro’s case is the only one with a display.
