Chris Martin has revealed that years of playing live has left him with tinnitus.
The Coldplay frontman said he had suffered from the condition, which can leave people with a buzzing or ringing in their ears, for about 10 years and had now started protecting his ears.
He said: "I wish I'd thought about it earlier. Now we always use moulded filter plugs, or in-ear monitors, to try and protect our ears. You can use industrial headphones, but that looks strange at a party."
The star has backed a campaign by Action On Hearing Loss about the potential danger of listening to loud music.
Rapper-turned-actor Plan B is also involved and said his tinnitus is so bad he is forced to sleep with earplugs.
He said: "There's no doubt it's been caused by years of being on stage and subjected to very loud decibels of music."
