The Buds FE have better call quality than the Buds 3 Pro. The Buds FE do a better job of blocking external sounds at a slight cost to your voice quality but you still remain intelligible. Whereas with these 'pro' variants they let more of the external noise in but your voice sounds better. Well, if noise outside is too much you get drowned out every single time and other noises can be distracting.
