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.

Disappointed I honestly was expecting more for the price of the wireless Bluetooth style. The sound can be heard loudly from others not wearing them. The small, flexible speakers are better than wearing earbuds but truly I don’t feel this was worth $99 USD. Disappointed 😔

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.

SleepPhones: A Gift That Keeps on Giving - Wow! I bought these as a gift for my wife. She absolutely loves them. They easily adjusted, just like the videos demonstrated, and except for the fantastic sound coming from the headband, she couldn't tell there were speakers in there. She started by laying on her side and still was amazed at how comfortable they were. Great design and implementation! Thank you!

Do not buy, bulky cheap headphones The eye cover itself is of good quality, but the headphones are massive and bulky, far larger and cheaper quality than I've seen in competing brands (seriously like a couple of inches thick). I don't know what they were thinking, when you can get a competing one in which the headphones are made of a soft, flexible material. It hurt to sleep on, and took over a month to get to me, not to mention the spam they sent my inbox the entire time I was waiting. Highly don't recommend this.
