Query: Logitech wireless were useless

I could not get these headphones to work with my iPod. These phones hadanother input that made it impossible to connect to my ipod. SomeiPods apparently have a remote control input, and these phones were madefor that. Most iPods do not have this input, including mine. I sent themback, and bought another brand at Best Buy. They work, but do draw a lotmore power than regular earphones. My reccomenadtion is, to stick withplug-in type phones, until the manufactues get it right.
