zeebeeThat review is full of crap!
Got the 422s put them on and I knew I was gonna return them instantly!!! Sound muffled, bass lacking, clamp force is out of this world, I mean my jaw wanted to leave my body, that's how strong it is, ears felt very hot after just ~15 minutes. I don't like them!
BluJay614Break in?!! What is this, a pair of shoes?...
They were waaaaaay too uncomfortable!!! I don't care how good they sound, if I cannot stand them on my head.
Didn't care for the sound either, plus even if this "break in"is a thing, how different would they sound...
TheChosenOneAll dynamic drivers with surrounds /spiders need to break-in. They are mechanical, after all. Shoes are actually a good analogy. Shoe leather is stiff when new. On drivers, the suspensions are always stiff when new which decreases bass response. Once the spiders loosen up, bass increases and the drivers “settle” into consistent performance.
