Regarding sound quality:
They've only had it for a day so I'm sure aside from Justine, they decided to reserve their judgement for the full review. Jims Review Room is a great source for detailed audio quality for audio products, can't wait for his review. He really puts a lot of effort in putting products through their pace and directly comparing them with their competition before he formulates an opinion on sound quality relative to price, size and comp - among other things.
These YouTubers are just jumping the gun for views, which I'm not mad at... but can see why we more thoughts regarding sound quality - but it's coming. Second video, more views, more revenue for them on a product line that is considered the most popular right now. Of course they're gonna milk it.
With that said, sound quality has a lot to do with the seal.
People think AirPods sound like trash because they aren't using them with a proper ear tip that helps seal in sound. Are they the best sounding, of course not, but for the size and convenience, they definitely DO NOT sound like trash when getting a proper seal - something I think Apple has realized with providing that with the Pro model.
Same with PowerBeats Pro. Prior to purchasing, I read many reviews about how good or how terrible they are. But the people saying they're terrible probably are not using the proper ear tip. It's amazing how much better the sound gets for me going from Medium tips to Large. The sound becomes more immersive, clear and rich.
I ended up returning the PowerBeats Pro even though they sound better than my AirPods. Once you go AirPods, it's hard getting away from that feeling of NOT feeling anything in your ears.
Hoping the Pro deliver in sound!
