Really commendable is the intent that goes into the making of this crafty portable set of speakers. Crafted in woody bamboo, these USB speakers are capable of producing across-the-board music at a 300-10,000Hz frequency. They will give a different look to your interiors and $30 is surely not a hefty price at all! So, you stand a very good chance to promote green acoustics at minimal cost and great aesthetics. Say no to plastic and yep, hail green to keep the environment clean!
