Lemmy Kilmister, founder of famous hard rock band Mötorhead, has taken to the stage at CES 2013 to show of the new Mötorhead-braned headphones, or MötorheadPhönes as they are now known.

The headphones focus-understandably- on the hard rock/pop audience. Mötorhead say the are "no weak-kneed, lily-livered, tin-pot and skinny sounding little pieces of garbage, no, that ain't Mötorhead's style".

According to the MötorheadPhönes website "Our headphones breathe the free-spirited-do-what-we-want-in-the-name-of-REAL-rock-and-roll attitude that Motörhead stands for. The headphones will sell for between £49.99 and $59.99 (UK price TBA)

The headphones are actually made by Krusell International AB, a Swedish company that specialises in creating smartphone cases, covers, and - now - headphones.
