I used the ipod that came with the bike and noticed it was too quiet at speeds over 50mph (vance and hines pipes dont help) and you had to remember to turn it off otherwise it would go flat also you could not change tracks etc so I put all the music on the Garmin Zumo 550 I was suprised that I could hear at 70mph and had to drop the sound down every time I slowed below 50 as it was too loud and it turned heads.
This may be down to the Zumo having more power and being connected to a 12v ciggy socket.
Myself does not really know the ins and outs of the outputs and watts etc but If you read about the ipod nano it says on a lot of the tech sites that they have no problem powering earbud headphones but struggle on the bigger stuff.
Output Power
Another major factor for media players is how much power they output. The more power they output, the better the job they can do at driving bigger pairs of headphones. A poor media player might only output 10 or 20 milliwatts of power, which means that it would not have the juice to drive a better set of headphones than the one they come with, limiting your options to add bigger and better headphones to replace the ones they come with. We measured the output power of the iPod Nano at 29.1 milliwatts, which is decent and enough to drive most headphones; this is enough for most in-ear and earbud style headphones. However, it will begin to choke if you try and use a very large or a particularly high impedence set of headphones; the sound will be low in volume, and it may sound overly distorted and grungy. So, the iPod Nano is fine for most earbud and in-ear type headphones, but it will have problems if you prefer a set of bigger, over hear headphones or want to use a set of professional cans; many of these will have a higher impedence and may have some issues.
