When I saw Lifepop's cool audio accessory bags for iPod and other MP3 players the first thing I thought was, "Cool! Perfect for scooter picnics and events!" The next thing I thought was, "How do I get one?" That being said I think these bags would be great for weekend scooter jaunts when you want some tunes at your destination, but you don't have a built-in stereo. They have several models which are both baggage and stereos at the same time.
The Groovemaster ($75)is a messenger bag with speakers and an MP3 player interface. It runs on 4 AA batteries. The Rocksteady Gym Bag ($130) is a bit steeper but a funky retro Adidas cool and comes in some flashy colors, but the black is my favorite.
The ChillOut ($50)is a combo cooler/AM&FM radio with aux hookups. This would be perfect for strapping to a rear rack/carrier and taking to the beach or park.
The auxiliary jacks for these bags work with iPods, Zunes and even PSP systems. So go forth and rock your scoot!
