Based on the release date (around 2022) and certificates, It's an old Paradise model. You most likely got them more than 3 years ago.
So you have a Phonak P50 rechargeable beige.
The left and right sides are the same. What changes is the receiver attached.
As I said, they are old aids. You can look in our classified section. Be aware that old aids with replaceable batteries are prone to fail after 4 years hence buying one like yours is a risky purchase. Rechargeable aids more than 5 years old are going to fail eventually due to battery wear.
You may want to check your local Merlbourne costco for newer hearing aids that are significantly better than the ones you have.
