The Bose Sleepbuds II are clinically proven to help the user fall asleep faster and stay asleep all night. The flexible wings fit evenly against the curve of the ear, while the ear tips, also made of silicone, form a gentle seal for passive noise reduction. The Bose Sleep app gives access to a library of more than 50 sounds, including noise masking sounds and relaxation content. The high-quality storage box pleasantly rounds off the appearance.
