I’m not a musician but a history professor who listens to lots of music.  I have to travel a lot and take a long trip by rail or plane with a set of Geraldine’s custom-made, perfectly-fitting custom earbuds – into which can be slipped into the earphones from an i-Pod or Walkman – and you could be on your way to paradise.

Lose yourself in the sounds of your music, uninterrupted by anything other than a ticket inspector if it’s a train journey, or an air hostess if it’s a plane – who’ll ask you to take them out for landing and take-off.  They’ll struggle to attract your attention though; the ear plugs are that good, and you’ll be lost in another world.
