Query: The bass is no more!!

When I first got these they were sweet!...then about a month into using them with a Panasonic RF-SW50R Shockwave Portable Radio, the speaker blew! you can still rock out to them if you only like treble, but the bass is GONE!! not worth what you'd pay in shipping!! But hey if you want to buy a new pair every month that would only be what...$84 a year PLUS SHIPPING!! Oh the radio is poop too, it took a crap about a month after the headphones! SWEET!! The only reason I'd give them a one is because they still partly work, otherwise it'd be Zero city!
