Its critical listening score is higher than every other truly wireless earbuds other than the Bose SoundSport Free Truly Wireless, but that has a total harmonic distortion score of 7.0 vs 9.0 on the Powerbeats Pro.
I’ve found in the past Rtings’ scores have translated directly to the listening experience, but as you said seal can vary for users and without a good fit the sound won’t be as good as the measurements imply.
I’m curious to test the Powerbeats Pro for myself since obviously that’s the best way to hear what they sound like. I’m pretty happy with AirPods so they’d have to be meaningfully better and fit me well enough to replace them. It’s all subjective, even though the Powerbeats Pro should sound better some people prefer the sound of the AirPods. I quite like them because they either fit or don’t, which is more convenient than testing different ear tips (which a lot of users don’t bother doing then complain about poor sound quality).
