Zirconia isn't just for ring-shopping fiances on a budget anymore. The diamond imposter is now being used to make earphones, of all things.
Panasonic's latest buds have been made with the material because it's apparently good at reducing distortion, according to Akihabara News. Another unusual feature of the RP-HJE900 earphones--one that will undoubtedly be more noticeable--is their removable cables. It's not entirely clear why one might want those, unless you habitually bury your buds deep into the aural canal and want a breakaway safety feature.
