i'm quite impressed. i had a bit of trouble setting the earphone up on my phone, but i think that was user error and not the fault of the product.
i love that the earphones charge in the case, so like iPods, once you remove the earphones from the case and place them in the ear, they connect to each other and the phone and your good to go.
the case is dinky, like the earphones, and it has now become part of my EDC. where as before, i had to make sure i remembered to pickup my earphones before i left.
the sound is unusually powerful for the size. i discovered, purely by accident, i have very large ear canals, so whenever i buy new earphones, i immediately swap the earpieces for the larger size. this is very important as a good seal in the ear canal is vital for bass reproduction.
as they are very small and weighs nothing , there easy to forget your wearing them, apart from the music playing in your ears!
for the price, there a no-brainer...
