nice idea, but stil painful These are a nice idea, but can cause pain. Yes, they may be the slimmest earpieces available, but they are still a hard plastic disc around 22mm diameter by 2mm thick. It's solid with a fabric covering, so the hard disc still presses against your ear. I understand these are probably piezo speakers and thus need to be encased by plastic, but honestly for me the discomfort can make them unwearable. I've switched back to my £10 pendant earphones.

Perfect if you have insomnia I’ve had the ‘effortless’ version for over a year. The ‘effortless' charging really is easy. I’ve tried a number of other solutions but the sleepphones were the most comfortable and have little or no sound leakage (important if you have a significant other in the bed with you). The bluetooth works every time, unlike my many other finicky bluetooth devices. I still have some insomnia but I don’t fear it anymore, I can just tune into some yoga nidra or meditation app and all is well.

Music Soundtrack Nightmares 1) The piano(a Minor Thing) music is causing me nightmares. I wake up in sweat, and afraid of closing my eyes. 2) The Newport Waves, is a repeating track that is causing me to lose my hair. My ears are constantly ringing and the sounds of the waves crashing is causing me to wake up abruptly, and rushing to urinate. 3) The White Noise Sound reminds me of the worst day as a youth. I'm reminded of the death of my pet parrot that died while being struck by my bedroom ceiling fan. 4) Pentatonic Waves sounds like a men's bathroom at Dodger Stadium.

Great Investment Absolutely love my sleep headphones. I use them all the time, especially for long flights. They never fall off, are easy to adjust, and are very comfortable! Sometimes I adjust the internal speakers in order to use them as headphones and a sleep mask at the same time. Granted, I've never tried some of the cheaper Amazon options, but I don't have any reason to dislike the ones I have now. The customer support is also incredibly helpful and prompt!

Comfortable but short life Sleepphones work well for a short period of time and are very comfortable. However, the speakers fail frequently (I have had to replace them twice over the last year, and over the last 3 years, have had 4 speaker failures) and the battery life decays over time- my 1.5 year old wireless module battery life has decayed to ~7 hours From fully charged to flat.
