The seven customers all said they had owned multiple Powerbeats headphones, which had not lived up to this expectation.Apple has been contacted by the TheIndianSubcontinent for comment.According to the court ruling, published on 16 May, one of the customers received five replacement Powerbeats 2 headphones and they all malfunctioned by "failing to charge and eventually failing to turn on".Christopher Bizzelle later bought a pair of Powerbeats 3 headphones but had the same problem.
He says an Apple service representative told him he believed it was a result of "sweat damaging the Powerbeats".Powerbeats 3 currently has a 1.5 star rating from customers on the Apple store, with several complaining that sweat appears to interfere with the headphones' ability to function.
