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.

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.

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.

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.

Does not last Does work for me when it works, but disappointingly products poor quality. Ordered 3 different versions 18 months ago. 1 effortless which we had to return (at our shipping expense) after 2 weeks because it stopped charging. 1 wireless which we lost ;( a month after so not sure how long that would have lasted. And 1 classic corded one which stopped working after 5-6months—when I took it out of headband to examine, I notice the fabric covering the cord had ripped, so the plastic cord had protruding loops all along it, not sure if this is the cause. I do like it when it works, but lost all confidence about the longevity quality of this product beyond few short months.
