i bought these headphones, and within a couple days, my little radio that i use at work broke so the sound only worked on one earbud. the player was old and it was a cheapo so i figured it just died, no biggy, and went out and bought an ipod. within 3 days, my ipod was ruined. the sound cut out the same way. these headphones, using the adapter to make them 3.5mm makes the plug over an inch and a half long, acting as a lever, and therefore greatly increasing the amount of force a small bump, which normally wouldn't do any damage, does to the solders inside the player. $250 down the drain! do NOT buy these headphones unless you ONLY plan on using them with your cell phone. if you use these with anything that needs the 3.5mm plug (which is anything other than a cell phone) it WILL break it. not possibly,...WILL break it. do NOT buy these to use with the iphone either, as the SAME thing will happen to it. all in all, i lost $285 dollars because of this problem. $250 for the ipod, and $35 for the headphones, which i will never use again. BEWARE!!
