Coldplay 's Chris Martin has revealed his girlfriend Dakota Johnson has helped him to improve shows for hearing-impaired audience members thanks to a special gift she gave him.
The 32-year-old actor gifted Chris, 45, a SUBPAC which is a vest that allows wearers to physically feel sound frequencies they might not be able to hear.
The singer-songwriter then decided to hand the vests out to hard-of-hearing audience members at Coldplay shows.
