Re: I need invincible headphones!
Sorry for asking the obvious question - but what in the heck are _you_ doing that's killing your gear?
You do realize that with any headphones (as well as earbuds amd in-ears) you need to handle them by the earpieces not just yank them around by the cord, right?
Most headphones that cost more than $10 can last for years - not weeks.
But to answer your question - there is no such thing as invincible headphones - as they all have cords which are always susceptible to mistreatment - including ALL of the nice beefy sounding and constructed models folks have recommended earlier in the thread.
