I spent a lot of time at CTIA Spring 2011 last week, and I saw a lot of new products there from i.Sound and DreamGEAR like the Cinema Sound iPad stand and the i.Sound Power View.
This particular one I could not find on the i.Sound camera, but I have had a chance to try out this mini Speaker. It is very simple to use as it just plugs in the headphone jack of your MP3 player, laptop computer, and plays some pretty good sound.
Of course, it does take batteries, and it runs on 3 AAA to get it going. All in all, it is perfect if you need just a little extra umph for your sound, and this has it.
As I said before, I did not see this in the i.Sound catalog, and was given a chance at the CTIA booth to try it out to review. I believe that the person at the booth said that it was about $14.99.
