Got M5 w/ Mic today. Wow, they suck.... relegated to sweaty gym headphones, I suppose. I can't even justify the $20 price.

UnaSalusVictusBurned them in for 10 hours. IEMs should not need much burn in, there is little flex to achieve. I think people just hype them too much. I should have looked at Head-Fi reviews before committing to this, they're generally average.
Reebzypop on head-fi or mp4nation forums and see if anybody wants to trade you, you may find somebody willing to trade something more suited to your needs, hell, ask somebody here whos unhappy they got jives to trade you....as teh jives are likely better sound sig for your desires then the m5.
