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.

Poor customer service The SleepPhones I received were faulty. I contacted the company well within the 30 day return period but it has taken a long time, with much emailing back and forth, for this company to agree to provide a refund and I am still unsure if any of the postage will be refunded. They seem unfamiliar with basic consumer rights. Avoid.

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.

Only worked for a year The headband style sleepphones are really great if you are a side sleeper. I found them very comfortable although every time I put the headband on I have to push the speakers around in the fabric for a while to get them to sit in the right place. They are not tethered in any way within the headband. I have had no trouble with bluetooth pairing or recharging them. The reason I am giving them a two star review is that after about a year of use they now produce various buzzes, whines, and hums through the speakers making them useless. This is not acceptable for a product that is priced as though it is a premium product. I have now purchased a similar headband from another company which has cost about a quarter of what I paid for these and works just the same.
