Piped music with SimpleSpeaker for iPod.
SimpleSpeaker is a very small and light stereo loudspeaker which works without batteries. It can be connected directly with the headphone jack of your iPod without using any audio cable.
The foldable design of SimpleSpeaker allows it to use the ipod both in horizontal and vertical position.
The SimpleSpeaker packs and travels easily and enables to use the iPod even as a travel alarm clock.
This sells for $10, probably cost $2 to make. Authentic Chinese packaging, I think this was made for the Chinese marketplace. Horrid tinny sound. Comes with two speakers, one would be plenty. At maximum iPod volume this unpowered speaker puts out just enough music to awaken a light to medium sleeper. It is compact, though the sound jack always protrudes.
For the price, weight, and size it's worth sticking in luggage so the iPod can be a travel alarm. There are much nicer speakers for a bit more money and heft. I think for this purpose a "Lollipop" mono speaker of a bit better quality with sound jack that rotated internally would work better and could sell for $12.
