Just received the two pairs that I ordered. Very mid-range centric. No issues w/the treble, Bass light--a little better when i swapped the foam plugs for a set of Spinfit cp800 tips. Very light and comfortable to wear. I'm hoping that these break in a little. Did a quick comparison w/some Panny RP-HJE120-K, Sony MH1c and some LZ A4 iems.
jb70they dont burn in much, but tips make a huge dif, try sony hybrid style tips or klipsch/ety compatible mushroom tips(one flange with a long stem) but, one thing that can change the sound, and think before you do this, remove the nozel filter, i did it on mine, that lasted 5 years before one ear died, im not at all sorry i got these then and am very glad my buddy let me know they where dropping for such a great price....they are so damn comfy......so eays to sleep in them :)
