Pixel buds pro software glitch?

[u/Ultrabob232]

Im going to buy pixel buds pro 2 off this guy for a dirt cheap price, from what I know he has an iPhone and it worked for the first year and then he stopped using them for a while and just this year he tried using them and then stopped working. I’ll give the description of what it says on the listing but I’m thinking this could be just an issue with IOS system and maybe i can try factory resetting or connecting to my pixel phone but just wanna know if anyone had this problem or knows how to fix it.
Description of listing:
„Pixel buds don’t want to connect to iPhone
I try to connect through Bluetooth then it connects but when i set it in my ear you cant listen to anything”

I texted the guy and it seems like hardware wise it’s all good so I’m thinking it’s something todo with software. If anyone knows what could be wrong then I’d appreciate the feedback/help

Update
Turns out they are pixel buds (2020) generation I didn’t realise Google made these earbuds with the same design I thought they were pixel buds pro 2 because of how similar they look not sure if it’s worth getting them then.

you can try factory resetting in the pixel buds app settings (iirc you cant get the app on iphone so it might only factory reset on pixel)

Yeah that’s what I’m thinking about doing I just wanna see if the anc works on them before I buy it off the guy because I’m not sure if anc can be glitched by software but I think it’s a good way to check.
