best headphones ive ever used for detecting, have tried all the above and the MAZ range, and to be honest they damage and fail just the same as any other headphones
the ones below will last as long as you look after them, i purchased mine 3 years ago and they are still running good. even after dropping them into the river they still worked like a trooper.
for the price and free postage you just cant go wrong.
