Looking for a good pair of IEM.

Budget: RM 150 - 400 (Quality prioritized)
Player: iPod, Macbook Pro
Usage: Music 90%, Movies 10%
Source: MP3
Type of Music: Wide range ( R&B, Trance, Classical)
Personal requirements: Excel in noise isolation / comfort. Excellent bass and clarity, as my previous IEM's not bassy.

Thanks
