On the plus side there is a generally somewhat high processing acting as the originals UEs, especially the plug for your MP3 player (or what one may also connect his UE headphones) looks a bit better. Disadvantage - and that is certainly a matter of taste - is the worse comfort for me. About the inset with the original metal strap on the ear can argue with me that has caused a major maintenance. If the replacement cable does not hold much longer (11 months in original), I'll probably switch back.
