I really wanted to fix my xcape ie and compare the two but i'm having the hardest time repairing them myself and getting no answer from head-fi for my problem here:
http://www.head-fi.org/t/593788/xcape-ie-6-wires-in-headphone-cable#post_8164170 among other problems like soldering really tiny wires.
out of box the vsonic's treble is so incredibly harsh. almost rediculously. it might just be because I've been only using a T50RP but I don't think I've heard headphones with this much sibilance. Did you notice this too and did it clear up with burn-in? or am i just crazy lol. it has nice bass though and ok mids. just upper mid and treble is bothering me like crazy.
Are you sure you didn't buy the GR07 lol? I've never heard sibilance with these and I'm quite sensitive to that. Are you sure you are getting a good seal? Are you using EQ?
