Using this for meditation. Apps hold big library of sound that can be loaded and unloaded to/from the device. The device is almost inside ear completely so when one sleeps on one side, it won't hurt the ear. Highly recommended
I was not at work on the day it was delivered. I have now received the sleep buds ( in don't play music). It is almost 5.30pm
Sorry about the previous message.
They are comfortable but I can't change my answer to yes
