Hello iRobinpro,
Good Evening
I’m using Airpods 2nd gen and i have an idea of upgrading to Airpods Pro 2nd Gen TypeC wheather i can upgrade or i can stay with Airpods 2nd Gen.
Airpods 2nd Gen is going good only and has warranty,
Is it good to upgrade now or i can upgrade later
If you have iphone 15 then upgrade to type-c or else stay with 
cable
Good evening bro. @Irfan bro suggestion is correct bro. Based on your iPhone model you have to decide here. if you are going to get airpods pro 2nd gen with USB C based on your iPhone model. just to make the cable carrying or managing easier.
If your airpods 2nd gen is working good, then you may stay bit longer. there are no rumors or leaks about airpods pro 3rd generation. Only airpods max is due. other than that, do decide based on current airpods 2nd gen condition.
Both models ku ena difference irukunga robin bro? Except charging port
No difference in audio quality bro. same version but iPhone 15 launch appo users new va airpods vanguravangalukaaga usb c port oda release pannuneenga. as airpods is an important accessory for iPhone users. same cable carry pannikalaam appadinu thaanga. no other difference.
Ok, thank u bro…
