My 2 cents...
After lurking a loooong time on this site, reading and reading again to find something to isolate from the metro, with nice sound and good price, I finally bought M9p. It was my first time with iem.
This was one year ago, more or less. At that time, I had a Nokia 5230 phone, and I had to contact MEEL because of contact position that was different from my phone versus the cable. I don't know if this is clear, but MEEL CS sent me FREE a small cable to bypass the microphone. Nice CS, very fast on email.
I was an happy customer.
After one year of listening, I'm still that customer.
- My Nexus One phone is compatible with the micro.
- The cable doesn't make knots, even if not stored properly (people sometimes look at me very surprised to see how the cable is "auto-rearanged" with no effort when it looks like a mess).
- My music sounds great. (from overbassed Primus to Philip Glass...)
- The isolation is great (I don't hear the bass sound of the metro (Montreal) neither other conversations or... other guys music).
But last week, I though I had lost them. I began to look for new ones (Shure, Klipsch... not the same price, and obviously some issues about durability), and of course MEEL.
In fact, my wife found my M9s in the washing machine, in a shirt, after a complete cycle.

My wife was laughing, but I plugged them and... tadaaa ! They still work!

So thumb up to MEEL!
ps: I'm currently looking for the S6 with looks really cool, too. May be in a couple of weeks... 
ps2 : I would like to say the same about Timberland CS in Canada, but they are just inexistent. No CS at all...
