I just got mine about an hour ago. I kept the first version of the Air Pods (the ones that came out, what, in 2016 or something like that?)
I am not a "true" audiophile, but I do appreciate depth and decent audio.
Coming from the first version, I can immediately say 2 things: first, audio is much more richer and deeper; second, the Air pods Pro are much louder - even without noise cancellation.
I have the volume slightly below half and I hear everything very clearly and the bass is booming. Turn it to around 75% volume and I get LOUD audio and LOUD AND BIG BOOMS for bass. That rarely happened with Air Pods 1.
I have it set so Siri can alert me to texts, and my mom texted me and it was a very smooth and soft alert with Siri alerting me what my mom said. Impressive, that's for sure. That's what I want these earphones to do!
Audio blows me away though. From most of the reviews, I thought audio was poor or equivalent to Air Pods 1. I can definitely say, the audio is fantastic. Blown away by it honestly. Well worth the price premium for this alone, quite frankly. If this is "poor" audio, then damn I need to try these other earphones I've seen mentioned here!
As for comfort, I am probably in the minority, but I LOVED the Air Pods 1 design and I LOVED that they were extremely comfortable for me. They slipped out occasionally, but nothing too bad. I got over it eventually. I honestly hate silicone tips, and that's one of the most attractive features for the Air Pods for me. The pressure for all types of headphones and earphones with silicone tips I have tried all sucked and gave me a headache. The silicone always got slippery because I have EXTREMELY oily skin (not by choice) and these types of earphones always slipped out. That's one of the reasons why I LOVED Air Pods 1 for not having this.
I was slightly hesitant going to Air Pods Pro for the silicone tips. But if any company can make me like silicone tips on earphones, it's Apple. I tried the medium tips and settled on the small ones for now.
First impressions of Air Pods Pro: I completely forgot there was something in my ear. They are lightweight, snug, comfortable. With NC on, I definitely feel some pressure that gives me a headache, but I only had this for an hour so I can't exactly comment on this being a larger issue or not. Overall, comfort is great. Hasn't slipped out of my ear yet, so whatever silicone these are- good for Apple!
I am pretty impressed with NC. It never was a make it or break it feature for me, but I'll definitely test it out at the gym tonight over the loud gym music that plays. Bass with NC is killer, holy hell. I listen to quite a bit of EDM and I'm feeling the bass all the way in the back of my skull. Woah. The volume isn't even 60%+!!
Can't comment on battery life, obviously, but my Air Pods 1 were great. I used them every day, at least, and every day when I went on the treadmill, to the gym, or for a walk. I always forgot to recharge them, and battery was never an issue. I got Air Pods 1 day 1. The original pair I had had volume and other issues, so within the first five months, Apple gave me Air Pods 1 replacements. I've never had a single issue since then. So say they came out exactly 36 months ago, I've had Air Pods 1 in commission every day for at least 30+ minutes for 31 months, no issue. That's impressive and well worth the money. I hope Air Pods Pro last just as long. In fact, I'm handing Air Pods 1 down to my sister for like $20 because they are still in near-perfect condition.
Overall, thus far, I am very impressed with Air Pods Pro. I am still hesitant on the silicone tips and headaches. But so far, these things are winning me over. The vent in the office I am in is completely silent with NC on. That's INSANE!
I like the long press and double press too. I never really used this feature in original Air Pods because they were really confusing and i always ended up with Siri even though I never ever wanted Siri by pressing on the side of the Air Pod haha. I can pause the music, and skip music, turn on and off NC. All with touches. I'll definitely need like a week or two to remember the 1, 2, hold taps, but overall, I love this feature.
Air Pods 1: 7/10
Air Pods Pro: (so far) 8.5/10
