They're a decent set of ear buds for the price. They connect quickly, they fit easily back into the case, battery life is as expected (around 4.5 hours), they charge slowly, they fit pretty well in the ears and don't feel like they will fall out.
The sound quality is not great though. Don't believe all these reviews saying how incredible they sound. Look... for the price they do sound decent, but if you are primarily going to be listening to music then your ears are going to fatigue very quickly. They have muddy bass that booms, the mids are ok, the highs are very harsh and echo as well as distorting sibilants (example: hi-hats should sound like TCK, instead they sound like TCHHK.
I bought these primarily for listening to podcasts while I was walking the dogs, and for falling asleep. Listening to spoken word is great but I strongly recommend you pay more for a better quality pair if you intend to listen to music primarily.
