I live way out west. I travel in the train's quiet coach and used to spend my life quarrelling with people who were making 'just one quick phone call'. I bought an ipod and noise cancelling headphones and this, which is the only thing I have downloaded, and I keep it on loop. My life has changed. Against the soothing crash of waves, I can once again read and work. In the few seconds of silence as the cycle begins again, I sometimes hear a stir in the carriage around me. It is somebody else, quarrelling with someone about their noisy conversations or mobile phone calls. They should get sorted and buy this.
