Hi. Time for me to upgrade from my Sennheiser IE8.
 
I'm looking for a pair of IEMs that have similar sound characteristics as the VSonic GR07 (ie strong bass, great detail, warm sounding and great isolation). My budget is $500, however the IEM *must* have a 2 year (or longer) warranty. I am not a fan of the Shure SE535's sound, and I think I've had enough of Sennheiser for now to consider the IE80 (they're great, I just want to try out something new). 
 
Any suggestion is greatly appreciated.

I believe most of the Shure and Westone line from earphonesolutions.com have a 2 year warranty.

How does the UM3X compare to the Westone 4?

I've only had a very brief listen to the UM3X, so I can't really give much of a comparison; however, I did a quick search and found this thread. Hope it helps.

There's actually a lot of threads if you search thread titles for "um3x w4."
