The next time you're out traveling, don't settle for the mediocre speakers on your smartphone or laptop — upgrade your mobile audio with the Soundmatters Dash7 Speaker ($250). One of the slimmest, lightest high fidelity Bluetooth speakers available, this little unit measures three-quarters of an inch high and weighs less than half a pound, while still packing plenty of sound. It features Bluetooth connectivity for wireless listening, or an auxiliary input if you don't mind being connected. With 12 hours of Bluetooth battery life, and as much as 20 hours if you use the auxiliary cord, you won't have to worry about it dying on you. Available in range of colors, this speaker also includes an international charging kit, cables, and a carrying case.
