heaphones

I am currently using a pair of Skull Candy 50/50s which i think perform well for their price, but i'm looking for something a bit better. I am equally concerned with each of three things: 1. Low end frequency response (i want to hear tones below 30hz with clarity) 2. Mid and high end clarity...

So I have these headphones that are motarola and I'm not sure what model they are, but I can't figure out how to hook them up to my iPhone, I turned bluetooth on on my phone and all it says is searching for device
