Using wired c type earphones

it would not damage anything unless it's a crazy shady product which would be illegal to sell to customers in most of the world

but of cause depending on the third party implementation, they might just not work for outputting audio.

Usually, you should be able to use most third-party headphones with a connection via USB-C with your iPhone 16e without any issues.

Will this cause any damage to the phone?

It shouldn't.
