Query: Goodbye Sony, Hello Sennheiser!!!!!!!!!

I had to relinquish my old sony headphones into the trash can (or recycle it, for those who are environmentally conscience). It served me very well for the last 10 years or so. When my sony headphones broke, I was literally in tears, but when my new Sennheiser headphones came, my mourning came to an abrupt end. The sony headphones are great, but after wearing them for about an hour or two, my ears would hurt, due to the force of the foam that would press against them, but with the sennheiser headphones, they cover my ears completely, allowing me to enjoy whatever i hear minus the discomfort. oh did i mention this company rocks?!?!?! I've received my sennheiser the day BEFORE the actual estimated delivery date!!! how freakin' awesome is that?! Will definitely repeat patronage with this seller!!!! buy from them, you will not regret it.
