Query: Nice sounding but don't hold up

These headphones have a good sound but they will not hold up. The wire is thin and flimsy and eventually they will fail. Sennheiser has a nice 2 year warranty that they honor and I have had to use it 3 times in 2 years with these headphones. My sets were not abused. I was pretty easy on them but just general use will stress the flimsy wiring. I cannot recommend them.
