I guess the title summarizes my ordeal. Basically, These three are the only ones I can afford (they're discounted in a local headphones store, at anextremely low price) If anyone has both headphones to test, please do compare them.
Mine are holding up nicely at some number of months in. The polymer or ABS or whatever it is of which they are constructed is obviously adequate for my kind of use. All in all, I am very pleased with my purchase. I've banged mine around a bit and they are fine. For what it's worth. One Evo user's experience. Evaluate it as you see fit...
My friend's Superlux became muted in the right channel after less than 2 months of use! To me it seems to be the case that with Chinese/Taiwanese hi-fi brands, what you get in sound quality, you lose in build quality. Same thing happened to my GR07. I liked them a lot, huge value for the price, but I don't think I will buy another pair again.
