I expected decent sound at the price SleepPhones are sold at, and I was not disappointed. In fact, I was VERY surprised at the quality of sound those little speakers put out. To get the full effect, you really do need to make sure you have them positioned over your ears well. You can still hear them if they are shifted a bit to the front or back, but it’s very obvious when you have them sitting over your ears correctly.
Because the headband and system design is practically weightless on your head, you really get a surround sound feel. I have a pair of wireless earbuds I use when mowing the lawn and such, but it’s very obvious they are there due to how they sit within my ear, but with SleepPhones it sort of feels like you are sitting in a room with a well-designed sound system since you can’t really feel the headband or speakers.
The power button also serves as a bass button of all things, and the difference is slight but noticeable. I found no complaints with sound quality as it was crisp and clear without distortion of any kind.
The SleepPhone’s sound quality is on par with, if not a bit worse, than the Apple EarPods that come with the iPhone and this is considered one of the best earbuds for ASMR.
