They're tolerable given the price, but I'm going back to my Panasonic ErgoFit RP-HJE120K after these die.
Very disappointed given Sennheiser's reputation. I know their expertise is in headphones and not earbuds, but the designers seem to think humans are just heads with two short earholes. I have to *shove* them up my ear, bending the cord. I still can't quite get a good seal. (Yes, I've tried different tips.) The sound seems decent, but my pesky ears are in the way so I can't confirm. Also the bit that holds the two cords together keeps falling off.
The metal bits are actually metal and not shiny plastic though.
