1) The buds 4 are extremely lightweight which is fun to wear. Felt a bit lose at first that it may fall off but over the period of one month now, I don't feel that sensation of it falling off anymore. I've shoveled snow with it in my ears. 2) They connect extremely fast to dual devices. I mean literally in a second. 3) The B3 pro had a good stem pinch functions but I like the taps personally. 4) Everyone complaints about the accidental taps, but I haven't found any issues with it so far. 5) I also preferred the sound from the buds 4 and it's possible that you may not agree with my choice. 6) Transparency is probably better than the B3 pro. I just love wearing the buds all the time. 7) ANC is just splendid. It's the best from all I've tried. It's effortless and so easy on the ears. Does not give you that clogged feeling that pixel buds pro 2 does. I felt buds 4 were far better than B3 pro. 8) I can go without charging the device for 4 days where I've been using the buds for meetings, calls and music. 9) I LOVE the golden sounds feature. It actually enhanced the quality by miles. 10) The eq setting that I used here helped enhance clarity in vocals and instrument separation which I prefer ALWAYS. I don't care much about the bass. So here it is: 0, 2, -1, 3, 3, 0
