I have apple earphones for my iphone 12. I have been using them since January and in about the end of February they stopped working, there is also no damage or debris.

maybe the wire or connector is broken

if it was me then I would try them in another device with the same connector like another iphone or ipad to verify it's not the connector in your iphone which is broken

Yet. they do have Apple people because they deleting harmless posts.

Earphones are next to impossible to fix. The person is going to need another pair which they will have to buy. They would not have to buy an expensive set of headphones were if Apple had not taken them away because their headphones would have been newer.

uh oh, what are you going to do now Apple, since you took those out of the box along with the charging brick .
