Jamming equipment is illegal to use in the UK as it violates section 8 of the 2006 Wireless Telegraphy Act. You can have your own choice of music through an ipod or other MP3 player. If you are bothered by the music or conversations of others use full headphones rather than 'in ear' ones.

Piped music is a modern curse. I hate it. It's never what I would choose to listen to, whether it's a radio station or other recordings. And I have very catholic music tastes. You sometimes get this sort of piped music on coach trips, and you'll never suit everybody with it.

Users of MP3 players should keep the volume right down, to avoid hearing damage and getting pummeled by someone sitting next to you who just hears the pss psss pssh trebley sound that leaks out. But the worst of all are people who try to listen to MP3s on their mobile 'phones but though their tinny speakers rather than earpieces.
