Question Bluetooth issues

[baileyboy125]

Hi, I recently bought a fairly cheap pair of wireless earphones from amazon due to the great reviews (ENACFIRE Future) with Bluetooth 5.0. I bought them mainly for connecting to my PC when I don't really feel like wearing headphones. They're great except for one problem: the audio lag on PC is terrible. It has to be at least 500-600ms. My motherboard (Gigabyte X399 DESIGNARE EX) has built-in Bluetooth 4.2 which is what I've been using. When I try connecting the earphones to my iPhone 6 which has Bluetooth 4.0 the audio lag is negligible so it must be something to do with the connection to the PC.
The PC is less than a metre away from the earphones so range is not the issue.

Please could I get some help on rectifying this issue.

Both. However I can switch between the two. Handsfree only sends audio to left earphone and quality is garbage, but switching to normal headphone output sounds good and is what I've been using (but has the lag issue)
