Is it normal for wireless headphones to pop when you plug the 2.5mm in?

My Momentum 4 pop when I plug the 2.5mm connector into them while they’re powered on. I’ve tried plugging the equipment in in other orders but it always does this. The pop is quite loud. Is this safe for the headphones/amp?

are you playing audio when you are plugging it in?

if not might be an issue, if yes it’s rec’d to stop/mute the audio when plugging/unplugging things

I never play audio while plugging things in, including wired headphones. But my dongle is connected to my pc and is powered on, in standby mode (because no audio is playing; auto standby). Whether I plug into the dongle or my pc does not seem to make a difference.
