Out of 3 IEM Blue Boxes I participated in recently, my Vsonic VSD1si's are the only pair with a balanced frequency response. One pair (Brainwavz) is painfully bright, and another (BlueEverBlue) is very muddy. How difficult is it to make IEMs with a reasonably flat response? I think I'll skip the next Blue Boxes.
Anyone with the VSD1S find that if they move slightly you just get a huge amount of white noise? If I move whatever I have the earphone plugged into it seems to go static until you move it back into a position that it likes.
Can anyone who can read it confirm whether or not the tag on the VSD3 suggests burn in? I may have to extract them from the drawer where I retire all of my shitty audio equipment that isn't worth selling and give them another shot if so.
