The clunking will mostly go away, turn into clinking ... sorry
It persisted with me for almost a year where I noticed it. Sometimes I noticed it more during quiet times (brushing my teeth seemed a favorite time for it to happen). Or shaving.
I think it's tied to strength, flexibility and overall a more well structured capsule around the device. I think it just takes time for the strength to grow appreciably, and the more active we are the more likely it will clunk until it gets strong enough to tamp that down as well.
I'm now at three years, just had an hour long yoga class yesterday, doing all sorts of poses and stretches that I could not even have imagined doing again. When I do them, I don't have any problems with clunking during or afterwards.
Once in a great while, I get a weak clunk. I think... So while it's a hippy fact of life for some of us, it does pass and attenuates to the point of unimportance. The second one may clunk as well, my second did.
