The earbuds are intended to ensure better sleep with noise suppression and provide sleep tracking. At first glance, the new Sound core Sleep A20 look like classic earphones. However, they are not designed for music enjoyment during the day, but are intended to ensure more restful sleep at night. With their air-filled Air-Win design with Twin-Seal ear tips, the new generation is said to offer up to 1.8 times better noise reduction than its predecessor, the Sleep A10, according to the manufacturer. Among other things, they are equipped with a 4-layer noise masking system and are designed to better suppress bothersome ambient noise such as snoring, city noise and the like. Anker promises that the special design means there is no annoying pressure on the ear and auricle and that they are also suitable for side sleepers. The new Sound core Sleep A20 can play various sounds from a personal library or other content. The manufacturer specifies a battery life of up to 80 hours when the supplied charging cradle is used. Lastly, the earbuds also enable automatic sleep monitoring, including sleep position tracking, via the Sound core app.
