Purchased after about 2 years with the S22 Ultra. The S22 with Exynos, the S24 with Snapdragon. Result: Huge (and I mean it) difference in battery life.

From there, the positives:
- Super build quality, as one would expect
- Better cameras (main and 5x zoom)
- Better speakers
- Much brighter screen (makes a difference, especially in sunlight)
- Still has support that improves things (a new s/w is expected to enhance the camera in August and the same is rumored for the next version of One UI with Android 15, 7.0) - https://www.neowin.net/news/one-ui-7-poised-to-significantly-improve-the-galaxy-s24-ultra-cameras/
Edit: November and I'm still waiting for it. Samsung seems to have put all its weight on One UI 7.0.

The negatives:
- It doesn't have 10x zoom but the better 5x zoom camera balances the difference (with crop) and it might even be better than the S22
- Same (and unchanged) design, with the only difference being the removal of the curve from the sides (I personally prefer it)
- Expensive spare parts, I haven't encountered it, but it's good to read https://www.androidauthority.com/samsung-ifixit-partnership-story-3456726/

The so-so:
- The stylus, even if it were missing, wouldn't bother me at all
- I don't feel the extra speed compared to the S22, I don't play games
- The same applies to the extra speed in accessing storage compared to the S22

In short:
If you have an S22 (without battery life issues) or (especially) an S23 (which also has Snapdragon) avoid the purchase. You will gain very little for the money you will spend.

If you don't have the above phones (or something similar), you will get a phone that handles everything, doesn't lag anywhere, takes excellent photos, continues to improve, and has one of the best build qualities on the market. You will find it hard to part with it because the hardware has now far outpaced the software, so we are now waiting to see what impact artificial intelligence will have and what hardware needs it will create.

User of both protective cases for the S22 Ultra, this and the Spigen GLAS.tR Platinum Tempered Glass.
Overall satisfactory experience, but the two products have some differences:
1. The installation of the Spigen is much easier, as it includes a built-in level. In the case of Whitestone, the first ampoule went to waste because I didn't have a level and it immediately slipped off the surface of the phone. Fortunately (perhaps due to this lack), the company provides adhesive protection films for the buttons, speakers, microphones, etc. of the phone. The experience with Spigen is far better.
2. The experience with Spigen is also better for another reason: when the liquid from the ampoule falls in the case of Whitestone, you have to tilt the phone (watch the video on YouTube) to make it go to the center of the phone. With Spigen, the liquid falls where it should, so one less step. Also, in the case of Whitestone, the phone detached from the guide at this stage (it doesn't have a back like Spigen) and because the liquid slides very easily, the second ampoule also goes. At least with the third ampoule (there are three in the package), I managed, but I ran out of ampoules with the second glass.
3. Compared to Spigen, the fingerprint works flawlessly, much better than Spigen, as if the glass doesn't even exist.
4. The glass is more sensitive than Spigen's. It already got a barely noticeable crack with a small drop.

In a few words, the product is quite successful. I will buy a second one, so I will have three glasses with three ampoules, and I plan to apply them with the Spigen guide, which is better.
And in this case, it would be useful if the ampoules and glasses were sold separately without having to buy all the other accessories in the package.

I will not talk about the positive aspects that previous reviewers have mentioned. I will focus on the points that are far from perfection.
1. Application (app): Sometimes it has some glitches. I play music with the UAPP and even though it shows that it's playing, I can't hear anything. I need to restart my phone (OnePlus Nord) and then it's okay.
Update: The latest firmware update (1.2.6) solved this problem, which was the main issue. Now I give it an excellent rating in terms of connectivity.
Update 2: Another point of criticism for the application is the equalizer, which only has a few settings, just 5. I believe it would be better with more options.
2. I would like the material around the headphones to be less smooth for better grip (a bit rougher or stickier in the hand).
3. I would also like a combination of gestures for "answer/end call" and "volume adjustment" on either earbud. You can't have both active at the same time.
4. The quality of the case is good (good plastic), it closes securely and doesn't slip in the hand, but it's not on the same level as the headphones. It seems a bit fragile and falls short compared to similar implementations by competitors (e.g. Klipsch), which are metallic.

Overall, I think the most discussed issue is the size and fit in the ear. The medium-sized tips that are already placed on the headphones fit perfectly for me, and I never felt any risk of them falling out of my ears. Also, I haven't experienced any pain or discomfort in my ears while wearing them.

Other than that, if you have the budget, don't hesitate at all, especially during Black Friday, it was a great opportunity. I don't regret it at all.

Update 2: The connection issue returned with the 1.3.3 update, not as severe but it's still there. I don't know if it's the headphones, the device, or the application. It's probably the latter because I randomly discovered that the headphones are connected properly, I can make and receive calls without any problem, and as soon as I end the call, the music starts playing without any issue.
Also, regarding the connection, it's good (for those familiar with Developer Options on Android) to leave the LDAC codec on Auto. If you set it to the highest setting (990 kbps), there are some connection issues. Auto works just fine. If you haven't dealt with this setting, you won't encounter any problems.

Update 3: The problem became more pronounced with the subsequent updates of the phone and headphones, and the headphones were checked by Sony's service, but no hardware issue was found. OnePlus is not responsive. If you have one of the two (phone or headphones), don't get the other. I'm considering either changing the headphones or the phone (leaning towards the latter). It's a shame because the headphones have excellent sound quality, but the usability issue cancels it out.

Update 4: With the 9.0 version of the application, the connection issue improved significantly, around 80% if I have to quantify it. If there are any further changes, I will mention them in the future.

Final update: The BT connection issue was resolved with some updates from OnePlus. However, based on my experience, newer versions of OnePlus have a high chance of having new bugs, so I would recommend that those who have a OnePlus device should not purchase them.
As for one of the considered downsides of the headphones, which is the multipoint function and simultaneous connection to two devices, Sony announced that they will add it with an update in winter 22/23. So another point in favor of the headphones.
Overall, I am very satisfied with them and I highly recommend them.

Update post-final: Changing phones from OnePlus to Samsung, there is no functional issue (connectivity or otherwise). The multipoint connection works flawlessly and there really is no reason (aside from ear anatomy reasons) to switch to a different type of headphone.
