You can connect wired headphones via the USB-C port of a Samsung smartphone using USB type-C to 3.5 mm jack adapter.
With this variant it can unfortunately always happen that an error message appears on the display with "The connected USB device is not supported".
This error message is unfortunately due to the following cause:
Special USB adapter required for wired 3.5mm headphones
Unfortunately, Samsung smartphones only work properly with the in-house accessories. So if you use a USB type-C to 3.5 mm jack adapter from a third-party supplier, this will result in the message "The connected USB device is not supported" being displayed.
This can be remedied by using the original USB-C Headset Jack adapter from Samsung. If you connect it to the USB C port of your smartphone, there will be no more errors on the display and you can listen to music over your wired headphones without any problems.
So that you don't have to search for a long time, we have selected the original adapter from USB C to 3.5mm jack:
- Samsung Type C jack adapter EE-UC10J
Unfortunately there are no uniform standards yet, so third-party accessories often do not work 100%. Therefore we recommend to use original accessories of the manufacturer for smartphone accessories if possible.
We hope that this will resolve the error quickly and conveniently.
