Hmm, I can't even remember. Might have been the medium Comply in my left ear and the large Comply in my right. Oddest thing is my right ear canal is actually smaller, but the inside of my ear doesn't mesh well with the W3 housing, so I can't get it to sit flush (hence, the seal breaks and SQ suffers). I may try more odd size combos, but for now, I will stick with what works consistently. Happy camper with the W3s right now.
What do have to sell me at a fair price that I can use and that can finance your custom tips?
