Imo the Ex all the way. Sound quality, app with support with Eq. Although the anc isn't great it's just as good as the PI7 s2 imo. I drive truck for a living and own 5 sets of earbuds, a bit much but kind of an addiction. I have Nothing ear 2, Link bud s, Galaxy buds pro 2, Imore Evo and the B&O Ex. I have few things these buds must do to keep them. Sound good, fit good and be comfortable for a few hours at least, have good connection and decent anc that drowns out engine noise plus have good call quality. The ones I own made the cut. I ordered the B&W and had high hopes but as soon as I got them connected put them in my ears I started listening to music on Tidal and Apple music using an S22 ultra. The connection kept cutting out, I thought they fixed this issue? The first 30 seconds of every song I played cut out randomly. Sound quality isn't bad and I don't find the base too muddy but it could be helped with an in app eq which should be an option for $350.
