Anker's New Sleep Earbuds 4 and 4 Pro Improve Noise Masking

Anker has introduced its latest Soundcore Sleep Earbuds 4 and 4 Pro, designed for individuals who sleep on their side. The company states these new earbuds offer extended battery life and enhanced active noise cancellation (ANC) capabilities.

The earbuds incorporate the same audio masking technology found in last year's A30 model, aimed at reducing ambient noise like snoring. Both the 4 and 4 Pro models feature a contact area that is 20 percent smaller than the A30 buds, which Anker claims will improve comfort for side sleepers.

The charging cases for the earbuds support wireless charging. Notably, only the case for the 4 Pro model includes a display, indicating its charging status.

Anker has not yet provided specific details regarding audio streaming features for music or podcasts on this new line of sleep earbuds.
