Excellent quality sound!
I was VERY impressed with the sounds from these ear-buds. Excellent for the price. The only issue I have is that, for me, they are not great for running. The buds are a little heavier than most (possibly due to extra circuitry to get the high quality sound?). You can see this in the pictures. The sound control also adds some weight. When running the inertia of the weight of the earbuds causes them to come out so they require a lot of attention. 5 stars for quality and price, 4 stars for range of application. But still quite happy with the sound quality - I just don't wear them running.
