Hello, unfortunately not.

Hello
Officially, according to the manufacturer, it is max. 5.0. I think that's enough. I would say that the earbuds are 5.3, but are backwards compatible as prescribed by BT. And this difference will not be noticeable. After all, the manufacturer has an interest in it working everywhere. As far as latency is concerned, I would rather use a cable. That's my opinion. Safe at home, maybe not on the mobile.
