Does your smartphone, tablet, or laptop need some extra oomph in th e audio department? If youre like me, I use my smartphone for enjoying stre aming music while I am working around the house, at the beach, or on the pa tio enjoying some drinks with friends. However, with the mantra of mobile d evices being smaller/slimmer is better, the built-in speakers leave a lot t o be desired. Fortunately, some companies have taken notice and now offer p ortable speakers for your mobile devices.
