Say goodnight to snoring, traffic and other distractions that prevent you from getting quality sleep. With comfortable ear tips and soothing sounds, Bose noise masking sleep buds are engineered to drown out noise so you can fall asleep, stay asleep and wake up refreshed and ready to take on the day. Bose sleep buds do something that earplugs and sound machines don`t: They comfortably seal out noise while delivering sounds that have been optimally tuned to mask those noises that interfere with your sleep. You might think that sleeping with earbuds can`t be comfortable, right? Don`t worry-these super tiny and truly wireless sleep buds are built to stay comfortably in place all night long. To fit most ear sizes and shapes, the sleep buds come with three sizes of Stay Hear+ Sleep tips (S/M/L), which are designed with a fin that conforms to the upper ridge of your ear. So even if you sleep on your side or move around, they`ll stay put for a good night`s rest. The rechargeable battery provides up to 16 hours of use-enough for more than a full night of sleep. The included charging case stores, protects and charges your sleep buds when not in use. And when unplugged, the case also delivers one additional full charge-perfect for travel. The Bose Sleep app makes it easy to set up and use your sleep buds. Just download the app, select one of ten preloaded soothing sounds, set your desired volume level and choose how long you want to use your sleep buds for during the night. You can select the same settings every night or experiment with different options to find what works for you. You can even set a wake up alarm that only you will hear, so you don`t disturb the person sleeping next to you. Think you`ve lost a sleep bud? No problem. Just use the "Find My Buds" feature in the Bose Sleep app to track when and where your sleep buds were last connected to your phone.
