This BoomCase from Mr. SiMo brings a whole new meaning to the term “portable speakers”, as the speakers and whatever electronics are necessary are contained within this vintage old suitcase. This 8-pound case is capable of pumping a total of 30 Watts from its two main speakers and top-side tweeter for up to 10 hours via its internal rechargeable battery when hooked up to your audio device. The BoomCase will set you back $295, though if you’re willing to throw in an additional $20, you’ll get the added benefit of an integrated USB charger.
