Seven customers from various US cities have taken the technology giants to court over their new line of Powerbeats headphones, after claiming that they don't hold their charge for as long as Apple advertises, and they are not as sweat-proof as the product description claims.
And according to the BBC, a US judge has ruled that the legal action can go ahead, though only "in part".
District judge Richard Seeborg said the sweat-proof claims "require amendment" as customers had not explicitly specified whether they had sweated while wearing the headphones, but added that the challenge regarding battery life could proceed.
Apple had promoted the Powerbeats 2 headphones as having six hours rechargeable battery" and Powerbeats 3 as having "up to 12 hour battery life", and all seven customers have claimed their pairs of headphones had not met this expectation.
According to the court ruling, which was published on May 16, one of the customers received five replacement Powerbeats 2 headphones and they all malfunctioned by "failing to charge and eventually failing to turn on".
The customer claims he then bought a pair of Powerbeats 3 headphones instead, and had the same problem, and alleges he was told by an Apple service representative that the problem was caused by "sweat damaging the Powerbeats".
BBC News claims that Powerbeats 3 headphones currently have 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, despite the claim that the device should be sweat-proof.
Apple had asked for all claims to be dismissed.
