I got a pair of free Powerbeats last year and promptly replaced their terrible eartips with a leftover pair from my MEElectronics Sport Fi S6, which worked OK. However, this week one of the tips came off in transit and I can't find it anywhere.

I ordered some Shure eartips to try and replace it. I thought they would be compatible but they ended up not fitting. Hoping someone here might be able to recommend eartips that fit, preferably triple-flange style? I'm open to trying something else though.
