Got mine yesterday (XP3).

test few songs after open the box. compare to my old EP630 (im not audiophile). Much2 better. Then burn in around 15 hours until this morning. Compare again right now. The sound much2 better and seriously left my old iem behind. makan asap.

I cant explain if its fast, warm, whatever. But to me. xp3 suitable to all songs and the best thing. compare to other rm400-500 iem. This one is a steal...

1 month after using XP3... I can say... worth every single cents that I've paid.
1st 10 hours is so so... Then burn for around 50hrs. Now, I can hear sounds that i missed before. Even 10 years old 128bit mp3 feel different.
If you're on a budget. go for it. if still not enough, save a bit, then buy this one. No need to puasa 2-3 months for student. cheers...
