Powerbeats Pro 2 - Very weak bass

Hi! I just purchased the Powerbeats Pro 2 and run the ear fit test multiple times, with all the different size tips, and it always fails. Also the earbuds sound very tinny, again regardless of the size tips I use. I've noticed there's very little bass compared to the AirPods Pro 2 earbuds I have (which have the best sound ever, but fall out of my ears during workouts, which is why I bought the Powerbeats). I must press the earbuds hard into my ears to get anything approximating the bass I get from the AirPods Pro 2 earbuds when they sit lightly in my ear (and, actually, to get the Powerbeats Pro 2 fit test to 'pass') . I feel like I must be wearing these wrong or something. Can someone guide me through how to get the sound I see I should be experiencing from every review I've read?
