No response from customer services I emailed twice (including one minute after I ordered) to say that I actually made a mistake and had wanted to buy the more expensive model. Never received a response from their email. Just ignored me. Very disappointing customer service. I am left with the cheaper version which I didn't really want.

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!

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.

Fantastic customer service I have had problems with my SleepPhones v6 Classic Headband Headphones (Corded) (loose wires), BUT they have been brilliant about replacing them, quickly and with no quibbles. I've rarely had such good customer service from any other company. Make sure you buy them directly from SleepPhones!

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.
