Maybe you wanna try $4.42 earphones?
No joke. I just bought them, and I can turn the volume up to a rate where I almost have to put them out to prevent serious damage, but the sound is still totally clear. I haven't tried expensive earphones yet (most expensive I tested being about 40$), but these are just everywhere superior to them.
The shipping is free, worldwide.
I mean, 100$+ for earphones which production costs CAN'T be over 5$? That makes no sense.
DealExtreme: $4.42 In-Ear Stereo Earbuds (3.5mm Metallic Green)
I own them. I can hardly imagine better earphones at that price, the bass is decent and not that dominant, mids and highs VERY balanced. Maybe you could try them and write a comparison with your high-end earphones?
Of course they aren't perfect though. They don't sound very vivid and a bit muffled. But still very good.
