As much as we love a great pair of cans for listening to music or taking conference calls at home or work, traveling with large, over-ear headphones on a daily basis is kind of a pain in the ass. On the flip side, most earbuds or other headphones that we would consider daily commute-friendly sound like crap. Enter the Boomstick. Compatible with any set of plug-in headphones or earbuds, Boomstick gives you better definition and a better listening experience using proprietary algorithms that can augment the audio quality of any source and any headphone. With a simple one-button user interface and 14 hours of battery time, it should easily get you through an entire week of commuting without a charge.
