@RyanDuncan check that there is not a gap or space between the ear and the eartip. See more detail here Galaxy Buds Tips
However perhaps the tips do not work for you, some customers have found that memory foam ones already mentioned are more comfortable and a better fit. See some examples here https://www.amazon.co.uk/s?k=samsung+galaxy+buds+pro+2+memory+foam+tips
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
