Yelp 1 Ended up buying a pair to try them out since I left my pair of MDR-EX450 overseas and just wanted to have a pair of cheap headphones to use with my iPadMini.To summarize these are awful headphones out of the box, really bad sensitivity and completely lacks dynamic range and clarity, everything sounds muffled. Maybe I just need to burn them in for 24-48 hours straight and see if that loosens up the drivers.I have the MDR-EX255, MDR-EX450 and the MDR-EX650, each one is worthy of the EX name and an improvement from the previous model down the lineup, sadly these earbuds are a complete disgrace to the EX name. Not sure if I have earbuds from a bad batch since I don't remember the EX155 sounding as bad when I tried them out at Yodobashi Camera.
