I all ! first sorry for my English I'm french but i will do my best..
as the title say i find a way to listen training sound (like 20 meter beep test, or boxing ring bell)
and your mp3 in the same time. (without a iphone 4.... i hate those .. but only cause i don't have one ha ha)
the company belkin's build one of the first *portable* mixer. called the rockstar.
so when you connect 2 mp3 player (i currently use 2 shuffle second gen for its size and clothe clip)
to the belkin rockstar, you can hear them in your headphone simultaneous..!
i don't think I'm the first doing it but when i though about it lots of people don't know its possible..
i try it for Somme's training and it work really great !
here some pics to show you how it look like !
