Discreet
Good for the price. This works well for how I need it. It's discreet for sure. It does sometimes feel like it will fall out but when I use it i wear a headband over my ears so it stays in place better. Sound quality is good. It holds up well and I use it 4 times a week for 10 hours. I've dropped it in a toilet and it worked just fine. I will say that it did fall apart one time when I dropped it and it went back together easily and still worked fine. I have been through 3 of these and that's only because it's so small that I lose them. Oh and I have small ear canals so I use it without the silicone ear piece which also helps the sound come through better. I'll keep buying (you know, for the next time I lose it)

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!

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

Nice tiny cheap earbud.
Nice tiny little no-frills earbud. Plus: plays a long time on one charge, pairs reliably, decent sound, tiny and good for sleeping. Minus: uses obsolete USB-micro plug, only one bud, no charging case, died after 4 months. for the $10 price point it’s basically disposable, a good deal.

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.

Original model -- good. New model -- bad.
I originally bought this in the fall. I loved it. Comfortable in my ear at night, long lasting, fast re-charging, good sound for audiobooks. Then I lost it a few months later. So I ordered 2 as replacements. The replacements were a slightly different model -- and this model isn't as comfortable in my ear during the day or night (they feel a little bigger). And the volume fluctuates from very quiet to loud w/o touching it. I am not impressed with the new model.

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.
