Hi TB'ers,

does anybody have any experience of these?

Motorheadphones Motorizers.

Reading a guide to CES 2013 for headphones on soundandvisionmag.com, and the guy who's written the guide (Brent Butterworth) compares them to Grados.

Seeing as they're over-ear, this could be interesting

Interesting product idea. Weird since Lemmy/Motorhead are not known for "high fidelity sound", but maybe these phones are more brutal? Best phones for metal? Metal cans?
