I want to love the new AirPod Pros but struggling with the fit. Out of the box, I switched to the large earbuds and passed the Seal Fit Test. But with mild activity they, mainly the right one, came loose and even fell out. I switched to the medium caps and am getting better results but can still feel them loosen with mild activity. I may try the small caps, but my mind keeps wondering if this in-ear design just isn't for me. I mean, with the medium caps I am shoving these in to hopefully get a good seal only for the seal to loosen. So, should it be this hard? Should I be inserting them in as far as possible?
