For the last 15 years I've bought 3 pairs of headphones from AKG and I'm extremely happy with them (why 3 pairs, because the first one was stolen, I gifted the second one to my dad and I am still using the last one)
They are extremely durable, especially if you pick a model with removable cable. I've used the K702 almost every days for the last 6 years and it barely shows any sign of wear.
I personally love the way they sound but it's not for every one. They are more built for professionals with a very neutral sound but very precise.
