Pro2 I will keep, but purely for slightly HiRes sound and a much stronger ANC (even without foam tips). Are they worth the upgrade yes if you found the Pro1 a BIG fit. Are they worth it over other IEM, Yes IF you have a newish Samsung mobile.
Summary Sound = Pro1 vs Pro2 a bit clearer, a bit more detail, bass a bit more controlled, shame it's a scaleable codec, even my old Sony XM4 with LDAC allows developer mode to fully unrestricted sound.
Differences, much smaller and easier fit, my old foam tips do not fit !!!, a neat fit tester for getting the right tip size.
Fit and call quality plus ambient mode needs more time to evaluate.
I paid £160 after discounts and trade in, but only paid £120 for my Pro1.
Samsung Buds Pro ANC High + Foam tips buds- Samsung Fold3 - Qobuz 24bit, but SBC Codec
SCALE, SOUNDSTAGE = One big mush BASS = Lumpy and dull VOCALS = Obscured by bass BACKING VOCALS = Nothing discernible REALISM = Less Sounds congested and compressed PRaT = None DETAILS = Lacked detail MICRODYNAMCIS = Bass overpowering
SCALE, SOUNDSTAGE = A bit clearer BASS = A bit better at managing bass layers, still lumpy and dull VOCALS = Clearer BACKING VOCALS = Now clearer REALISM = Still a compressed sound PRaT = Better DETAILS = A bit more, transients them but now audible MICRODYNAMCIS = Bass overpowering
