i believe you have decided on getting the ES5 (judging from your postings in the stepdance and es5 threads)
if so, welcome to da club!
I just got my pair of JH16pro...and i would i have to say they are amazing.......
The basses is so strong and tight and controlled....it don't cover up any of the mid and high at all...
I listen to mainly R&B ish kind of music and it is very nice....
In saying that i have try it with softer music like some or mariah carey's "Through the Rain" and "Love takes time" and it sound as expected ...crystal clear...excellent sound stage.
So for song that are not to bass like unplugs they will sound or should sould the same as the JH13pro.
But for song that require a good bass punch ...i would have to say nothing else can compare as less not IEM.
I have demoed other top grade IEM like UE18pro and UM miracle I would have to say in trems of bass nothing can compare but for mid and high the only one that i could recommend that is equally as goo dis UE18pro.
BTW the JH16pro don't require and amp to push... I am using an ipad as a souce and it is pushing it fine...I only have the volume up to around 70% and i listen to loud music.
I hope my personal opinion helped
