Query: Great Travel Speakers

While I haven't compared these to other travel speakers, I can compare them to your average PC speaker, and there they compare very, very well, and yet are considerably lighter and more portable. I have used them traveling for my laptop, for a CD player, an MP3 player, and even the Yamaha Silent String travel guitar. For all of these uses these are great speakers. Of course they should not be compared to full size Boze speakers or high-end headphones, but for the purpose of a portable speaker they are outstanding. As noted, the speakers have their own carrying bag and the AC power supply works for European power. I wanted something to provide good sound on the road and these definitely are the ticket for that.
