Why is there a lag (delay) in sound in some Bluetooth headphones?

Question

Android

I have a full size JBL E65BTNC and a small true-wireless Mifo O5 pro .
When used with an Android smartphone, the Mifo gives audio lag in games and web browsing, while the JBLs are completely lag-free.
Where, in principle, does such a selective lag arise, and what could be the difference between

headphones from the question?

Answer 1

There is always a lag in bluetooth, somewhere it is less, somewhere more, it depends on the specific implementation, whether the manufacturer wanted to reduce the lag or not. The sound quality and, accordingly, the lag also depend on the profile used, it is possible that some not very good profile is selected in games and in the browser. This is for you rather on w3bsit3-dns.com with such a question.
