Hey all, I've been reading here for a while and thought to bring in myself with this video.
Hate to break it to you, but almost always a dented driver that's been brought back to its original shape will still not be as good as it used to be. The dent cracks the structure of the diaphragm or a similar irreversible change and it'll never be as good as before. The effect should be measurable and audible.
Still, it's most likely better than not bringing it back to its shape.
Clearly depends how hard they are dented in.
In my cases, it has worked always, except one time.
I could do a before and after measurement.
I agree on the measurement part, this should be visible, but a driver damage not always is audible. Still it all depends on the damage itself, how severe it is.
There are breakup modes in the material/diaphragm design anyway which makes small things like this unimportant (if not too bad). That's my experience anyway. Have removed dents with blunt toothpicks and doublesided tape on at least 20 headphones.
It's not the end of the world, I've undented a few drivers. Dents on plastic bubble headphone drivers are reversible if not severe. And I reversed a few dents on some big woofers.
I was taught that for the 650, just blow in the back opening (grill removed) and it pops right back into shape. Blew my mind.
