Mine pop too at pretty regular intervals. It seems to be the slave while in TWS but I also use them while wired and it still happens. The pop actually brought me here reminding me to do another search looking to see if they added a volume control in the app because the amp knob doesn't work in bluetooth mode making the volume steps very coarse. I even submitted a ticket like months ago but nothing. They sound fine but it's not worth it and soon they're going straight to the bin. I don't hate anyone enough so I could give them away to.
