Radians Custom Molded Earplugs (Red) https://www.amazon.com/dp/B002XULPSQ/ref=cm_sw_r_cp_apa_dfmUybBSJM18G
Yeah, if I take the risk of losing them they better be rock solid about the warranty for the price. Fuck Jaybird. Options literally 1/10 the price work just as well if not better.
Honestly the best option I have come up with are some Amazon specials for about $40 and I ditch the ear bud pieces they send along with them and get some custom ear plug stuff and form it up around the headphone.
I don't think they offer the ones I have anymore but they were ridiculously tough. I washed and dried them multiple time and I am notorious for sweating so much I kill headphones and iPods.
