This is the 2nd time on the first page you are looking for cans that will last a "lifetime" - Why?
Do you think "can" technology will stay the same, or do you think in 2-3 yrs there will be better stuff available at a better price, (like all of the other electronincs you own).
I have seen some excellent recommendations from many posters, and while you prolly can't repel down a cliff from them, they don't have any common premature failures reported, so please don't fret about how thick/tuff the cables are, (cause you have no need for them to last a lifetime).
Personally I have Klipsch, (and I also own Snap-On tools), because quality is very important to me.
Sometimes I can't affort the higher end stuff, (so I simply save another month or two until I can) -
