I've had the same problem as you. I have gone through at least 10 headphones in the last 4 years. My current earbuds are Shure SE110. They are definitely the most durable. Unfortunately you have to drop $100 on them. Do not get sonys because the wire is really thin (I've gone through 5) and v-modas wires are really thin as well (I've gone through 1) and boses are overrated (I've gone through 1). If you are willing to spend that much money go with Shures.
I keep breaking earbuds,i've gond through 3 pairs. usually at the wire that go to the earbud itself and to the connector, anyone
know a good pair of earbuds for my Mp3 player, hopefully somthing heavy duty...?
