Dear Audiophiles,

I'm going slightly insane. For the past few weeks, I've been reading up multiple reviews on head-fi and inearmatters to try and figure out what IEMs I should get.

Here's what's important to me:

1. durability. durability. durability. (I'm heavily in the gym, plus I run on the beach.)
2. sound quality. (I'm running a Sansa Clip+ rockboxed and I like my detailed sound, nothing overwhelmingly bassy. Mostly detailed electronic music, acoustic recordings and Lossless ONLY.)
3. budget. (I'm pretty flexible. Anything from RM150 - RM300.

I've looked at the following:

Senn. CX300-II
Soundmagic PL-50
Meelectronics A151
Fischer Audio Eterna V2

I'm drawn to the SM and the ME for the balanced armature and awesome reviews, but i've been told that the build quality is nothing like the CX300.

My head is going to melt if I read another review. What are your thoughts? Any suggestions?
