Yes, these headphones are compatible with the Samsung Galaxy S25 FE thanks to its USB Type-C connection.
The Galaxy S25 FE has a USB Type-C port, which is perfect for connecting the headphones.
The Samsung EO-IC100BBEGEU earphones are compatible with Samsung devices that use a USB-C port, such as the Galaxy S24 FE, as they do not require a 3.5mm plug. These headphones are designed to work with Samsung devices that do not have this traditional plug.
Unfortunately, that is true. Samsung and Huawei (maybe others...) seem to take different approaches.
Be careful with the adapters too: Huawei CM20 does not work with Samsung!
