These look really amazing, but do they actually work or just for looks?
They do work.
These look really cool and amazing. I'd love to get a pair. But these earphones also seem to be the kind that look amazing but then don't work well or suck or break easily. Someone I know had something like this and it wasn't good. And a day later, it broke. These can only be returned if they're defected when opened, right? Were the earphone parts made from a certain company?
What size is the headphone jack? Is it 3.5 or 2.5?
