This may be useful so someone:





I know Joe likes his speakers but this would not be a great idea here abouts. Over the years I have spent an amount on intercoms and similar that could make a chap quite miffed that a he'd found the £24 solution last of all. This £6 set of earphones packed with epoxy foam stuff from a £12 make-your-own earplugs kit passes the Vaughn-Williams test * at speeds that are illegal in the UK. Just put the headphones in, roll the putty, wait 10 minutes and pop out the made to measure sound set-up. I am actually not that miffed as my test run was 120 miles of sunny Yorkshire in the company of said Vaughn-Williams, a bit of Shostakovich etc. (Plus some pop ditty about experimental lesbianism my wife must have downloaded).


* the speed at which you can hear the middle sections of say the English Folk song suite but not find the loud bits painful seems a fair test of sound quality. The helmet speakers supplied by the intercom people seem to pass up to about 50 mph while a unit I converted to ear buds is good for 60. Add the earplug stuff and you get more than another 10 mph.


My Galaxy Y, powered from the USB mounted on the Guzzi is passing the V-W test and mixing in very usable GPS commands.


Has anyone tried noise cancelling headphones? The sort that subtract noise a microphone on the cord picks up should work well, but are a very costly experiment.
