Arctis Nova 3 Popping

I recently bought 4 arctis nova 3's for an office setting
one user reported the headset was popping and cracking (only when playing quiet audio, not while idle)

I went and tested and all 4 headsets do this, in 2.4 mode, and in bluetooth mode.
is this a known issue with this headset? i cant believe all 4 are faulty

Tests were made on separate PC's and on phones, so the faults have to lie inside the headset?
