Soundcore A3i Vs Soundcore Lib Pro 3

Hi all hope everyone is well, just a couple of questions really , I love the new A3i that I have just purchased, however I would like to know how much different does the extra expenditure give you with the Liberty Pro 3s, I do feel I’d like a little more volume so I don’t need to have them at full for most of the time, and also if the two drivers really add to the experience. I bought these for general use when I go fishing or are doing things around the garden so it’s not the end of the world should they become lost.
However for serious hi fi listening from decent hi fi would I still be worth upgrading.
Finally if I do decide to replace or change to say memory foam tips , what are the size of both tips for both models please as I can’t find any information on spec sheets.
Yours thankfully for all your help
