Let the hive mind of Engadget get that for you.
"I just moved into a new apartment and have been reading about all of the new power strips out there, especially the green ones. I was wondering if you had any suggestions about which "green "power strips are out there with decent joules ratings. And when I say green, I mean power strips that have the remotes or switches to turn off all electricity flowing to certain plugs and with at least 2 plugs that are always on. I was looking specifically at sub $50 because I will need two, but if that is not possible I could be convinced otherwise. Thanks!"

Engadget Japan got it right: http://japanese.engadget.com/2009/06/03/mdr-nc300d/
Also worth noting, NC300D seems to use the same 16mm transducer as Sony flagship in-ear MDR-EX700, which has a MSRP of US300 of its own (though street price is US$200 now).
