I got my MP21 yesterday. First impression, good. apart from the in-ear earphone, I got 2 'C' like hook to put the earphone on your ears, 2 pairs of extra normal ear buds, 2 pairs of earplug style ear buds and 1 'Y' cable (not sure whats that for) together with a little bag. I havent test the mic yet but the button on the mic behaves exactly like the original iphone earphone. 1 click to play and stop song, 2 clicks to forward and 3 clicks to go backward.

All in all, its a great switch from the standard iphone earphone and really great price considering the fact that the original apple in-ear iphone earphone costs 300plus. BTW, the sounds were great. Love it. Definitely recommended.

I bought from this thread - http://forum.lowyat.net/index.php?showtopic=984152&hl=mp21

Sound quality is good. I haven't tried those high-end stuff so it is good enough for me. I'm also using PL11 and I can say that they are almost the same. It does not sound 'cheap' tho, if you know what I mean. For EQ setting, I use Pop.
