Following suit, Soundcore’s version promises a four-point noise masking system, a lightweight build, a comfortable fit, and virtually unlimited audio.  Soundcore says that the earbuds will block passive noises for a “truly quiet” night’s sleep. The ear wings and Twin Seal ear tips also seal the ear to block up to 35dB of noise in your surroundings. The Sleep A10 utilizes soothing sleep sounds via a noise-masking algorithm to monitor your surroundings and adjust the volume accordingly.
