Tokyo-based crap gadget specialist Thanko is usually known for selling USB stuff nobody needs. Their newest hit product doesn’t feature a USB port, but the target group for their Catgirl Earphones [JP] should be quite small, too. Marketed as a gadget for the Cosplay crowd, the earphones are supposed to turn your girlfriend into a cute catgirl.
The Catgirl Earphones are available in black or the inevitable pink (price: $20). If you live outside Japan and are really interested in getting the device, wait for Thanko to list it in their international online store.
