Thanks. I've done some more research on Westones and am now leaning towards the UM3x. Thoughts?

UE 900s sound like a good choice...probably on par or better than the Shure SE535s, but unfortunately its out of my price range. I'd like to get some earphones that are new, not used...who knows what defects or decrease in lifespan are in those used earphones. 

Hi all, I need your input on these 2 earphones. This is my first time buying high def earphones and my budget is $300. I've heard that the SE425s lack bass, but are very detailed and analytical. For the UE10s, I read that sound is fun and colorful with bass boosted a little, which may take some...
