Overview
- At IFA on Thursday, Sept. 3, Anker unveiled the Soundcore Sleep Earbuds 4 and 4 Pro plus two SleepLab bedside speakers as part of a broader push into sleep-focused consumer tech.
- The Sleep Earbuds 4 will ship in October for $229.99 and the 4 Pro arrives in November for $349.99; the Pro adds an in-ear PPG sensor and a SleepHub charging case with an integrated OLED touchscreen for phone-free controls.
- Anker’s SleepLab Pro speaker uses 60GHz millimeter-wave radar to monitor micro‑movements, heart rate, breathing and four sleep stages from the nightstand, but final MSRP, some hardware details and battery/portability specs remain unconfirmed.
- Anker says core sleep features on both earbuds and speakers will not require a subscription and provided battery-life estimates for the earbuds, yet it has confirmed the radar speaker is intended to track only the closest sleeper rather than multiple people.
- Reviewers are awaiting hands-on testing to verify radar accuracy versus wearables, the real-world effectiveness of BioSync adaptive audio and snore-masking, and to assess privacy, multi-user limits and the products’ practical benefit for sleepers.
