US retailer Brookstone has teamed up with Problem hitmaker Ariana Grande to release limited edition headphones.

The wireless headphones feature cat ear shaped speakers on top of the headband, and colour changing lights on both the ear cups and cat ear speakers. Grande commented 'Working with Brookstone to create these amazing headphones has been a blast. They represent my style - fun, edgy and unique and I know my fans will LOVE them as much as I do'.
