Sorry to barge in like this, but…
Not interested in Meta measurements personally, since they’re unavailable for purchase… But with future reviews and measurements in mind, it would have been amazing to see measurements with SpinFit W1 eartips going forward. They’re my favourite tips for comfort, especially since they have intermediate and super small sizes available, and they seem to make welcome changes to the sound most of the time for me. They have a considerably wider bore than CP100+, so you might want to at least give them a try since acoustic effects of wide bore tips seem to alighn with your anatomical expectations better with most IEMs (if I’m not mistaken).
