Yes if you sit still/not "chewing" and you still get popping, occasional squealing/white noise, I would guess you have a faulty bud.Agreed, with ANC off they sound pretty good (I prefer a slightly brighter sound than these have, tbh). I’m pretty sure I’m not doing any movement, though — I’ve worn IEMs for a very long time, and have had a number of TWS with ANC and never had this problem before.
The white noise seems to come and go on the right side. Like I said in my post a couple minutes ago, I’m pretty sure I have a defective one.
I'm going to call Sennheiser tomorrow.
