Jennifer Lopez

SAO PAULO: The World Cup got off to a faltering start on Thursday night when poor sound quality left many television viewers unable to enjoy the opening ceremony, The Telegraph reported.

Jennifer Lopez took to the stage to sing the official FIFA song “We Are One”, looking on fine form for 44.

But while those inside the stadium were able to enjoy her singing, the experience of many at home was hampered by “appalling” sound quality, which left the voices of Lopez and fellow singers Pitbull, the US rapper, and Claudia Leitte, a Brazilian pop star, sounding faint and “tinny”.

A source at ITV, which broadcast the ceremony in Britain, said that it had “no control” over audio levels because a single feed was distributed around the world.
