Never ending returns

I would like an explanation for why these headphones fail after just a few weeks of routine use.

I'm on my second pair, which just went out. As with the first pair and same as everyone else for no apparent reason, the satellite reception just stops. The display on the Pioneer Inno XM receiver shows the message "check antenna" or "no signal."

So far Belkin has replaced the defective ones without charge (you have to pay shipping to return defective pair), but bottom line is you almost need to have 2 pair and "swap" them out one pair at a time in order to keep one working. I do not think it is out in left field to have a product that last more then 2 month at a time.

I too have yet to find any alternatives. No one else makes anything similar that I can find. If anyone has found out the problem is with these things, I would love to know also!
