Hi Mr. H,

I'm delighted you like the M22ti's. There isn't any "break-in" time--what you in fact are doing is breaking in your own ears and hearing system to a new (and much improved) sound reproduction system.

Tests conducted at the National Research Council in Ottawa, Canada, of speakers used as "anchors" (good and bad) for our blind listening tests showed no significant or audible change in frequency response even after many years of use.

So break in those ears!
