S21 Ultra USB C Headphones not working

Got a new S21 Ultra a few days ago, and I am noticing some odd behaviour with my USB C headset.

The headphones seem to work fine with calls.

With media/apps - Often with the headphone plugged in, the audio comes out the phone's main speaker. Disconnecting the usb c and reconnecting it usually forces the audio to switch to the headset.

However, if I pause video/audio for more than a few seconds or switch apps the audio jumps back to the main speaker.

I do get an android notification saying "USB device not recognised" when it stops working.

the Samsung s21 ultra 5g does not have a jack socket to play music, you will have to use Bluetooth, I suggest that you check it out on Samsung tips which is installed on your s21 ultra

Are you saying wired usb-c headphones wont work with media/apps? I have looked through tips, couldn't find anything relevant.

When you plug the headphones in, pull down the notifications and click on media. Does it show headset? It should look like this.

Not sure if you don't realise this but USB C headphones exist and they work fine on pretty much every phone with a USB C port, including the S21.

@Kelsaor ignore the comment, it's completely false information. USB C headphones should work for calls and media, pretty much all sound should be directed through them once plugged in.

@joeeye It does, until I get the USB device not recognised notification, then it says "This phone"

I see, do you have any other device to test the headphones on? Also make sure the connection is flush and that it is not loose in any way.

Tried it on an S10, I don't get the "unrecognised USB notification" nor the audio reverting to main speaker after a pause. It does however switch to main when you switch to a different app. So Im guessing either the headphones or the Samsung USB-c app are the issue. May just bite the bullet and just get some Galaxy buds.

Hmm sorry don't quite know what the issue is. I have a pair of USB C headphones from my Note 10+ 5G I believe which seem to work fine on the S21 Ultra.

If you go for the buds Pro, quality wise I think they're great, however comfort wise I think takes getting use to. Good luck on whatever you decide.
