I do not own the models you’ve mentioned but there’re Ear (2024) in my Ears right now. I watched a lot of reviews choosing which buds to buy and still settled on the most expensive flagship ones.
Pros and cons of both models:
Buds Pro 2 have good sound quality for it’s price, battery life is great and there’s Spatial Audio✨ support (Why?). Case is more scratch-resistant and has a roller-button✨. BUT ANC features are ewww (probably everyone say about that) and some people talk about volume Imbalance between left and right bud.
Ear(a) are just Ear but in another case with longer battery life, the difference between chep and expensiv Ears is minimal in terms of sound quality, maybe (a) has a bit less high frequencies. ANC is better (nothing special). BUT (a) has only 3-band “equalizer” so if you prefer some specific sound it will be kinda difficult to get. It doesn’t have a wireless charging support (disadvantage for me lol).
Suggestion: just buy Nothing Ear, if you have specific preferences for sound, you know what is equalizer and how to deal with it. If you don’t, buy Ear(a). Don’t need ANC - Buds Pro 2
