Why is the Bluetooth connection between mobile phone and Galaxy Buds better than with Galaxy Buds and laptop?

With a laptop they are almost unusable because the connection is not perfect. One side becomes quiet or they are not syncron left and right for a short time. The laptop is new and should have Bluetooth 5.0

Because connections between manufacturers are always better than external brands

But it is really grumpy with the laptop and has errors every few seconds.

Well maybe it's because of my laptop maybe it's a bit older

As I said, new. Is an Asus Zephyrus

I recommend you simply take headphones for your laptop or you can check your headphones to see if they are suitable for any device other than Samsung
