did a lot of research, it came down between these few...
1. Etymotic HF5
Best isolation, but I'm a bit worried about getting used to the deep insertion style on this, is it possible to get good seal without a deep insertion?
2. Brainwavz M2
3. Sennheiser IE6
4. Monster Turbine
5. Monster Turbine Pro Copper
$130 used on Amazon... might not come with accessories though
6. Ultimate Ears 700
so guys, please help me decide on one, thanks!
