I have a system.
I destroy everything. the best i have found are these:
Nike Sport Motion
not earbuds, but they work better for me. most earbuds or headphones take a shit after a few workouts. I am a sweat-hog, ymmv.
these nike things last about 3 months before one side goes out.
So here is the "system"
-buy them (or others) at Best Buy. (20 bucks)
-Buy the geeksquad black tie protection (its like 4 bucks)
-every time they shit out (for me, every 3 months) go get a replacement set.
/tilltheendoftime.
what makes this work is how "geeksquad black-tie protection" and the factory warranty interact. If the device fails within the factory warranty period (1 year) geeksquad replaces it with an in stock unit and and your geek squad warranty resets at no cost. Basically, as long as they keep shitting out within 1 year of purchase i get free headphones forever. I almost feel dishonest, but fuck em.
