Thank u for the inputs. Now I would seriously look at other new or like-new IEMs within my price range(~$150). I already have RE2 but want better sound. I mainly listen to Rock, rap and raggae. After hours of reading in the forum, I narrow my choices down to super fi, Monster Turbine, ER4 and...

Recently I was offered a deal on UM2(<$150, three years old) , I only tested for a little while and it seems fine, so was the look. My question is, is it worth the money? Thanks

Compare to the cost of IEM, it's worth it

Just checked the web site provided in the OP, it's terrible.

I'm getting one of the two. Hope I won't regret it.

I've read quite a bit about UM3x and W3. Which one is better since they roughly cost the same?

I also have the overheating problem with m50. My room can get hot enough even with AC on(I live in Miami) so wearing pleat pads is not comfortable. So getting velour pads for m50 is not a option FWIR, maybe i'll get myself a pair of open cans at home, or any more suggestions for the pads?

1+ goes to M 50 even better amped(brighter, and more bass)

still not out yet? It's either this or 3 move. Can't wait
