A wonderful pair of headphones, with satisfactory sound quality!
Noise cancellation: A very important feature is the adjustable external noise cancellation, I haven't connected it to the app, but with a tap on the left earphone, it changes from 0% to 50% and to 100%. Personally, I consider it very important because when you go for a run in a stadium where it may be windy or crowded, you put it on 100% cancellation and it reduces everything and you can listen to music at a relaxed volume without getting tired. However, when you want to run on the road and want to hear cars, etc., you put it on 0% and you can even hear cyclists, as if you're not wearing them.
Sound quality: Personally, I am a fan of hi-fi sound and I was searching a lot to find a pair with nice sound. I was considering Sony's top buds, but they weren't suitable for running, but these are awesome, airy, comfortable with nice details. Very nice sense of depth, with nice bass for picky listeners... "top" for me.
Microphone quality: Quite good, they can hear me clearly when I speak, it struggles a bit with wind, but it's not easy for the microphone in the ear to capture speech (opposite direction from the microphone). So, personally, I am satisfied.
App: At first, they didn't fit me at all and I regretted spending my money, they were very soft with a very gentle fit compared to the previous wireless ones I had for running and I constantly felt like they would fall off... but then I went for a run and after 5km, I adjusted the right one only twice... so, very good fit. And after my fear of them falling off disappeared, everything was fine... **I should note that I have very soft ears and maybe that's why I felt them loose.
Battery: The battery in the case doesn't decrease at all, I charge it once a month and use the headphones 2-3 times a week for 1-2 hours. Also, I should mention that for some reason, the last time I used them, they had 20% battery but played for 1 hour (at moderate to high volume) without turning off!!
Volume: The case is not bulky, it fits easily in a pocket, bag, etc., lightweight, and of good quality (doesn't look fake). The headphones, in terms of size, are not tiny but their size never bothered me. Quite lightweight.
Signal quality: I must say that once it's connected, it never disconnects (with Samsung A71). I always keep my phone in a closed pocket, once it fell when I was running and I realized it because the signal was cut off and I found the phone 15 meters behind me, so you can understand...
I believe it's worth its price, I got it on Black Friday for 190 when the regular price was 279, so it's value for money for less than 200. You buy them and forget about it.
Hope I helped :)
Update 16.11.2022
After 2 years of use, they function like new, working flawlessly. I happened to travel by ship and watch matches on my phone, and it gave me a battery notification after 6 and a half hours (!!!!!!!) while playing at 80-90% volume with 100% noise cancellation!! 6 and a half hours for a notification!! And they turned off without a second notification after 10 minutes. Unbelievable! Value for money! I haven't thought about getting another pair of headphones from 2020 until now...
