I do have a pair of foam tips, but it's a bit troublesome for me to wear, just a matter of personal preference though. I found out that the V-Sonic tips are thicker on the front compared to others, maybe thats why it doesnt fit me well.

Quote:   I just got some Philips medium size eartips and it solved the volume problem. Thanks! Funny how V-Sonic provide me more eartips compared to the others but none of them seems to fit me well 

I am using a V-Sonic GR04 classic edition, it's the first over-the-ear style IEM I got. Anyway, when I'm using the IEM, sometimes when I turn my head, the sound will change, or worse, one side of the IEM will sound more quiet.  Is this a fit issue? or a problem with the IEM itself?   Thanks

Quote: Alright, I shall go to a headphone shop and test some cheap amp with their IEM, might pick up an amp if it provide lots of difference :D Although now it would be pretty hard for me to get the TF10 though, didn't purchase it at that time (2nd hand) :/       Jeez, those...

Quote: I certainly hope that's not the case though, I was like, it can't be, it's sound so similliar    So, in order to fix the impedance issue, I will need an amp, right? And is Walkman good enough to drive those high end IEM?

Quote: Ya they're triple BA IEM, the only better device I got is the Walkman E series though, is it comparable to the Clip+ and/or other cheap amp? I afraid if I buy another good IEM in the future it might not be good enough for those... Quote: I'm using 320kbps MP3, I do have some...

Long story short, I tried a UE TF10, Panasonic HJE900 and Phonak PFE121 last time, output from my HTC Explorer. This is my first time trying audiophile item, and TBH I can't tell much difference from my cheap Philips, I didn't notice all the goodies people talking about, like the soundstage. Now...
