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.

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.

I have owned these for over a year now & they're great I have owned these for over a year now. They are incredible. Battery life lasts all through the night, easily. They are comfortable. There are no wires tethering you to your phone. They are durable - cheaper alternatives, both wired and bluetooth, have invariably failed within a month or two. The components (Each speaker, main module) are replaceable should something break. Charging is easy. I cannot state enough how well designed a product this is and the difference it has made in helping me get to sleep.

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!

The comfort level of my sleepphones is… The comfort level of my sleepphones is excellent, I can actually sleep comfortably and wake up not knowing they have been there...no "tight" marks or sore ears!! The only issue I have found is the speakers drift if I toss and turn. Get that issue straightened out and these would be premier head sets. Soft, comfy, good sounding and a little wandery within the headband.
