If a housing change changes the SQ to the better......and Westone has no interest in reporting that....I find that grossly odd and irresponsible.
For newbees and onlookers here is where it's at:
Do you like to turn it up and rock out!!!!! UMPro30 is definitely the way to go. While it doesn't have great extended treble, the overall detail is very very good. Decay, vocals and overall tonality is unmatched.
If you listen at lighter, lower volumes I would surely recommend the W4 (W40) for the more laid back audiophile presentation and added detail retrieval.
It's that simple folks!!! I LOVE the W4 but it can't handle extreme high rocking out volume. UM3X/Pro30 CAN but it does sacrifice a little treble detail which is the whole point....at loud volumes you want your treble a little recessed.
As crazy as it may seem the $400 level IEM's still have an issue or two. You gotta pick your poison. Just to throw in another one...The SE535 is great in that it can handle loud volume with no distortion but it is overly midrange focused and the bass and treble sort of take a back seat. But is does have exceptional clarity even though that clarity stems from an upper midrange spike. Still a great IEM but I am just picking out its faults. An added underlying subwoofer fullness of bass to SE535 would be awesome (SE846).
