I am facing this weird issue with my iphone Xr whenever i connect to my oneplus bullets wireless (bass edition) specifically, (BTW i have more than 2 of those) i connect them there's some distortion/cracking sound when music is played above 60% and also if i quickly toggle volume from control center the connection stops and reconnects automatically. first i thought it's the earphone itself but no when i connect the same earphone with my android phone it's working flawlessly.
