The problem is your calculation and perception of the cost.  On Xiaomi Singapore's website is SGD19.99 + SGD5 delivery = SGD25 = RM66.  To deliver to you via Poslaju is another RM6.  What about the time taken to wait in front of the computer and compete with others to get it (just like AirAsia 0 fare sale)?  In fact, asking for RM100 is cheap.  Do have 3 sets of  brand new iF edition Pistons with me just to spare and have not intention to sell at all, at least not at RM100 

Beware of fakes!

I got mine today and will give it a try and post more reviews soon.

The packaging is really neat and doesn't feel cheap. Especially like the rubberized case which let you to keep your Piston tidy without tangling the cable. The programmable volume up/down key seem to work with xiaomi phone only and doesn't work with my Nexus 4. Well at least the answer phone button still works. Might retire my SE215 with this since it has comes with a microphone too. Am not too particular with soundstage when traveling since I'm only listening to 320kbps mp3 on the move.
