What are these

Are these good or are they like, OEM or something?

Looks like a piece of junk expecially since they don't even know the name of them just cw65.

I was thinking they were like OEM or something because of that reason.

I think they are aftermarket OEM replacement.

for 7 bucks each I'd try out a pair of them.
