My suggestion is to get the Westone UM Pro 50. I have owned W50 and Shure SE846. UM pro 50, for me, is the best value proposition and also great sound quality for my iPhone 6. With your budget at $900, you could stretch for SE846, but Westone fit is super comfortable and the price difference of...

One negative that I had with SE846 was the comfort/fit. Westone is wayyy better for me as the fit is sooo comfortable for long wear. Also SE846 is really bulbous and big and it moved a lot in my ear when I wore it during workout. That said, I still like UM Pro over Shure. :). That's my...

UM Pro 30 is UM3X's replacement model? And if so, UM Pro 50 is a still a superior model compared to UM Pro 30, except for the slightly extra bass? :-) either way, I am very satisfied with my UM Pro 50 and will not be inclined to listen to any other IEM for a long time to come. :-))

I am using my UM PRO 50 almost everyday. Great listening experience. Billie Jean on my ears now as I write :-)

UM Pro 50 all the way though :-)

I now understand what is a studio/stage monitor IEM. UM PRO 50's clarity is wayyyy better than the W30/50, Shure 846 that I owned. I cannot believe how clear I hear ALL the instruments with such separation. Wow!!!

Thanks. Will try a couple other tips and see whats the difference. Its so comfortable to wear just like any other Westone. 

Oh man, just got off hearing MJ's Thriller song. I have never heard all the nuances of this song this clear ever without missing a beat (literally). UM PRO 50 Rocks!!!!!!!!!!! Everything sounds so well. So far i have heard Guns N Roses - November Rain , America - Sister Golden hair, U2 - One...

Thanks smaragd. I just heard a couple songs and this is the right IEM for me :-)

  Holy F**ing crap. I just had a chance to use the UM PRO 50. I am blown away with the clarity. And, since I like a little (very little) extra bass, this fits my bill so well. I have tried SE846, W30 and W50 and long back UE Triple Fi 10 and Super Fi 5. This UM PRO 50 blows everything out of...

Thanks Spyro. Ok I will up the treble by 2-3 dB and then try. Haven't had a chance to listen to it yet.

I thought warm and lush is not the same as muddy and dull. :-)

Ok. Thanks. :-)

I heard that burn-ins are mostly for dynamic armature headphone and not for these. But anyways I will keep that mind.
