I need help with wireless headphones

So i'm looking at some wireless headphones, but i don't know how to tell which one is the best, in terms of comfort, sound (bass, mids, highs), and maybe not having problems with other wireless signals. Here are 3 i found:

Which ones in your opinion are the best? I do know that they cost differently, but i don't know if that's even an important detail. Also, will they work with an ipod nano?
