MDR-IF245RK 3.3 5 3 3
Great sound, March 2013 These headphones have exceptional sound. They're extremely clear, have amazing bass of all things and really deliver a quality sound experience. They are large and sort of require that you are sitting up or with your head facing forward. For instance, if you're being lazy in bed, you can't really adjust comfortably to lying on your side to watch tv with one ear on a pillow. It would be ideal if the headphones could twist to allow for that minor listening experience. Overall, they deliver, plain and simple. March 11, 2013
give them a try for yourself they pick up all of my neighbors cordless phones and any 2-way radios in the area February 23, 2013
Great Headphones, Great Sound and Quality These are good headphones. They have great sound and the included charging cradle is neat and doesn't take much time to set up. Everything you need is included in the box and if you ask me this is a pretty good price for what you get. January 23, 2013
