I tried out Anker's sleep-focused wireless earphones 'Soundcore Sleep A20,' which are equipped with sleep-inducing BGM playback and sleep monitoring functions.
The Soundcore Sleep A20 , a completely wireless earphone released by Anker on July 9, 2024, is not only a regular wireless earphone, but also a specialized earphone for sleep that can play sleep-inducing background music such as the sound of rain or a bonfire, and record the user's sleep status. The Soundcore Sleep A20 is said to be comfortable to wear and compact, making it comfortable to use while sleeping. I had the opportunity to actually use the Soundcore Sleep A20, so I thoroughly checked its appearance and usability.
