Dr. Dre has come under fire from animal rights activists for selling headphones which feature real fox fur.
The hip-hop star teamed up with designers at fashion house Oscar de la Renta to create a limited edition range of headphones, which are covered in "luxe silver fox", for his line Beats by Dre.
However, the new sound piece has infuriated bosses at People for the Ethical Treatment of Animals (PETA) and executive Michelle Cho has now written an open letter to the hitmaker, urging him to discontinue the collection and shun the use of fur and exotic-animal skins in the future.
She writes: "Foxes, minks, rabbits, and other animals - including cats and dogs - are bludgeoned, genitally electrocuted, strangled with wire nooses, drowned, and even skinned alive for their pelts. Most animals killed for their fur are slaughtered in China, where there are no penalties for those who abuse animals on fur farms...
"With so many fashionable, cruelty-free materials available these days, we hope that you will keep animals in mind and choose not to use fur or exotic skins in your collection... You have a tremendous amount of influence on young people - won't you please consider using your platform to advocate kindness toward animals by pledging never to design with real fur and exotic skins?"
