Gummy in ear headphone. I couldnt tell you much about the technical bits and pieces about these. They are only a fiver, ive got a pair and they sound good to me. Lots of good reviews also from other people that have bought them. They havnt got the inline volume adjuster which some people want but makes no differnce to me. Have been cheeper on here before but that deal expired so think this is best price at the mo.
