I recently bought some TaoTronics noise cancelling headphones. I thought they'd make the long-haul flight home to the UK less painful.
As an itirant miserable bastard I have found they also work to make long-haul life less painful. Sometimes I just want to switch the world off and step out for a bit. These headphones give me a bit a peace to recompose myself. Not as much peace as the electronic blinkers Panasonic is currently flogging though.
I think if I was that desparate I could probably achieve peace with a sack over my head prior to a short walk on a busy motorway.
