Got two on a twofer. Sound quality is better and louder than notebook speakers but not as good as other portables. Charges from usb 5pin mini. If you get a usb a male to usb mini cable, you can listen and charge, replacing notebook speaker.
Darn! I missed these. Bought 3 last time-they are really amazing, and tiny. Perfect for your phone or ipod/mp3 player.
AWESOME for strapping on bike handlebars so I can still hear the cars trying to run me over
