I find it's the wire that goes first, probably from all the twisting and tangling that happens day to day. At 5x the cost I could see wireless ones being cheaper, long term.
I still wouldn't want to muck about with batteries, etc though.
It's a really good idea to invest in headphones that have a detachable cable, if you are rough with them at all(basically any travel or commute situation). Then the point of failure becomes the internal connection, which mostly rests on build quality and how much you drop it.
Have you ever seen any earphones (IEMs) with detachable cables? I could see them being produced with short cables to the Y split and then plugging in another cable to the phone.
This would be perfect for me - headphone cables and wheelchair wheels do not mix.
I've had wires go on me as well, but for me it's more typically the housing for the earbuds themselves - they come apart - or the electronics inside - they just stop working.
