Wired Grados was the best i've ever had, but admittedly too much sound leak in and out. And 100% of my wired stuff wears at the end where it meets the phone. It starts with that cutting-out one speaker each step, and that's worse than nothing at all.

But, I find bluetooth devices cut-out frequently in cities, especially around cars and intersections. So I get packs of 5 wired earbuds for $5 total. One set of earbuds lasts maybe 6 months then onto the next. I've come to invest in the portable speakers I have at home and work.
