Tripp-Lite doesn't just offer power protection products, but they have several other areas of expertise that they are marketing. One area of interest for me was their notebook/laptop speakers. With no need for an external power supply, simply plug these into your available USB port and listen to your favorite music or movie on your notebook.
I have been using my laptop far more than my desktop computer and this was one area I wanted more sound without an outrageous pricetag. Tripp-Lite offers their simple Portable Speakers and an upgraded version of Premier Mobile Theater Speakers. With only a $20 difference ($39.95 and $59.95 respectively) it's easy to choose which pair would be right for you.
They come in silver or black and silver (for the premier version) and are small enought to pack into your laptop for carrying elsewhere. The Premier version comes with a carrying bag to make it easier for you to pack them up, but either pair would serve the purpose of sharing good sound with others via your notebook.
