I used to listen in acoustic and alternative genre. Im using sony mp3 player with fiio e7 portable amp. Right now im using a-jays 3 but im not satisfied by the sound quality. I don't need detachable cables, i need a simple iem with crisp and detailed sound. My budget for iem ranging from 4k-6k. I'm also looking forward for klipsch image s4. I need your good advice guys because im new in this kind of hobby. Thanks
Hmmm...I think there are better alternatives to the UM1 for its price. I can't recall if I had an opportunity to try-out the UM1s @ Jaben around three years ago, but based on what I've been reading @Head-Fi, the UM1 really won't cut it. Yeah, it's a BA-type IEM. But for its price, I think you'll be better served by the S4. Then again, I didn't enjoy my brief demo of the S4. Hmmm...what to suggest, then?
Don't you want give the Metro.Fi 220s a shot? They're only Php2.5k @Sir Leo's/meiroque/dranoel1490 tipidpc page. It can give IEMs twice (or even thrice) its price a scare.

A word of caution, though: since you can't remove them cables, there may come a time that they will harden. Or I may be wrong; perhaps UE has already changed the cables in them Metro.Fi 220s.
Better yet, wait for TF10s that will be FS'd. (I really am a UE fanboy through and through)
Hope that helps.
