Query: Defective

I ordered the sennhauser earbuds, cx 300 fromAmazon because the phones were supposed to be excellent for bass. When I played my music with bass I could not hear it at all. I have another earbuds which are much better, and much less expensive. I tried to send them back to Amazon but they state that it does not comply with a return. I tried Sennhauser and they have no way that I can return it to them. No where on the order was it stated that I could not return a defective item.
