Excellent so far!
I listen to a lot of audiobooks and podcasts and this tiny earbud is great. I've bought several of the same design because they fit my ear very well without the rubber tip. The sound is fine and the battery life is unbelievably long, often more than 8 hours. The one flaw in the design is that the two halves are vulnerable to separating and it's very hard to put them back together. This has happened to several of the previous ones like this that I've bought from different sellers. But so far this one is very solid!

small and discreet
I was reluctant to purchase this small earbud, as the reviews were mixed. I was also wary of the low price thinking it would be of poor sound quality and might not fit my ear well. But I am pleased to report that this earbud works perfectly for me. It charges quickly, pairs easily with my i-phone, and fits securely in my ear. I wear it during work and the charge lasts way beyond a typical eight hour shift. The sound quality is not the best but it is adequate, and I have no difficulty listening to music and podcasts. If you are looking for a small, discreet earbud, you should try this brand.

Too big and bad quality
Works but quality is awful, way to big not nearly as small as its competitors, and they only give you one earbud and it doesn’t even come with a case it’s in a little ziplock bag. I know the description says single earbud but I didn’t think that meant literally. Would not purchase again

GREAT for "covert" listening, battery lasts hours!
Compact and good enough sound for discrete listening and connected to my phone right away. It's been holding a 9+ hour charge which is GREAT. I use it during work shifts. It isn't invisible so "sound amplifying device for hearing" are great key words to use to describe it (also I'd recommend the more skin tone coloring) so I can listen to podcasts and audiobooks while working. It's only one ear, so the description makes sense. It sits pretty securely in my ear, but I dunno that I'd recommend it for sports (especially without the "leash" thing). Microphone isn't great for calls, but I didn't purchase it for that purpose. Only 4-stars as it's not comfortable to sleep with, as described. Also, they give you a few silicone ear adapters but I think there's room to make a universal ear adapter that funnels sound for better hearing. It can take a significant amount of small adjustments before audio is not so muffled in sound. Worth the price, I hope it lasts!

Works well, long lasting.
Long life, comfortable. Good for conversation, not wide range audio.

Mixed bag
I’ve bought 4 of these. The first one is great in terms of battery life, sound and price, I use it for Audible books, podcasts, etc, (not music) the sound quality was totally acceptable. So I got another one, still good to go until I lost it, so I ordered another. The 3rd one worked for a nano second and quit, wouldn’t take a charge either so I returned it and they sent another one and I ordered a 4th. Of the last 2 one of those works but the sound sucks, very tinny, hence my mixed bag headline. The battery life is great, love that and for the price I can’t complain loudly. I’d say give it a shot, if you get a good one you’ll be pretty happy! If I lose another one I hope it’s the tinny one ;)

Great Value!
Fantastic, someeone listened! These little earbuds were already a great value. They have now been upgraded after early responses. The eartips are now captured. No need to super glue them on as before. Additionally, they have upgraded the switch to be more tactile. Thanks for the changes. Great job! Great value! These little earbuds ate mighty. They come in an unassuming bag. They are as powerfull and long lasting as any of their competitors at half or even a third of the competitions price. Play time is great, longer than mu other earbuds. Interaction is with a small but accessible button. It provides tactile feedback without random activation with slight touches. My only complaint is that the eartips are unique. You might not be able to replace them if the two pair provided get lost or destroyed. On the other hand, replacing the whole earbud might be as cheap as replacing standard eartips. I have also used these without eartips at all and they are still comfortable, with no sharp edges.

A great little earbud
This works very well. And the price makes it so worth buying. The single earbud works in either ear and stays in well . The best part is that it works all night, unlike many other ..more expensive…earbuds.

The quality of the lithium ion battery inside the earphone is very bad. After using for one month, it's not charging any more. Hence, the earphone has become useless.
