AC/DC frontman Brian Johnson has said he is "amazed" after testing a new hearing device that could potentially allow him to reunite with the band.
Johnson was replaced with Guns 'n' Roses singer Axl Rose for the band's current Rock or Bust world tour, after medics warned that he was at risk of completely losing his hearing if he chose to continue.
But the singer has now tested a new in-ear monitor, and says that it could pave the way for his return to the band.
The revolutionary device is the brainchild of Asius Technologies founder Stephen Ambrose, who invited Johnson to test it.
The device works by removing static pressure and filtering audio until it is of a higher quality that is less likely to cause audible damage.
In a statement, Johnson said of the device: "It WORKS. It just totally works and you can’t argue with that. I was really moved and amazed to be able to hear music again like I haven’t heard for several years now. I can’t wait for it to be miniaturized so I can use it in every situation from normal communication, going out to noisy restaurants, to performing live music on stage."
