Happened to me, too. I got mine from ebay, so no warranty
Only bass-heavy recordings, and only really bad in some bass-heavy recordings... I've done frequency sweeps that don't do it to nearly the degree I've seen in certain MP3's. My guess is it's something to do with resonances(IE a 20hz and a 40hz wave gang up).
After about a week of being very bad, it went intermittent, and there were periods where I couldn't replicate it. I decided to try to live with it, and have been doing that for the past 6 months. It's been getting worse again in the last week or two, I might take up the Beyer tech guy's offer a while back of two matched drivers for $55 for me to replace them myself.
My guess for a few months has been that back when I had dead batteries in my CHA47, they recieved a blast of DC offset. But if you guys with META42's have been having problems, then I don't know.
I emailed Beyer tech asking how much one replacement driver would be. I don't think this was a public offer, but anyway, here is the response:

Hello,
There are two version of DT 770
The older version was 600 Ohms,
Newest/current version are 250 Ohms.
The 600 Ohms version are no longer available which means that if you are
going to replace one transducer you will have to replaced them both.
I will give you two of the 250 ohms transducers for the price of one which
is $ 55.00 plus $7.00 shipping and handle.
To order the above item please contact me @ 1 800-293-4463 or 631-293-3200
