Which if these wireless headphones is the best?

If you are interested in sound quality then get wired headphones. Wireless are convenient but poor qualty for the money. Like AVDaddy, I like sennheisers but the thing about speakers and headphones is that you need to get what you like and not necessarily what I like. If you want somethign reasonable get Sennheisers which did well in Which tests but if you want the best for you go and try things out with music you know. When you find a pair and think " wow I never heard that before in hat track," you have a winner!
