Query: Bad headset

I bought these a couple of days ago and loathe them. They sound great, but if you can't wear them it's useless. After about 30 seconds your ears start to ache and don't stop aching until you pass out from pain. Logitech should have tested them on people not rodents. I don't normally bother with reviews, but this product is such a stinker I couldn't help myself.I'm taking them back tomorrow.
