The Room Filling Travel Speaker

This is the travel speaker that uses any resonant surface to project music 360º. When placed on counters, tables, shelves, or glass, it produces, robust sound that implies a full-range stereo cabinet speaker has been hidden nearby. Its vibration resonance technology produces a frequency response of 80Hz to 18KHz for reverberating lows and crisp highs--a wooden tabletop will yield different nuances of sound than a glass tabletop. At only 2 1/4" high x 2" diameter, it fits easily into a laptop bag or carry-on. An included 4' long cord splits into USB for charging and 1/8" stereo plug. It also accepts a microSD memory card for independently playing MP3s. Its rechargeable battery provides up to 10 hours of operation from a two-hour charge via USB. (11 1/2 oz.)
