The resurgence of portable speakers have come back in fashion! Sadly ghetto blasters haven't quite made it back into the mainstream, but many other more compact solutions have come into the spot light.
Through very clever engineering, portable speakers of today are extremely powerful for their size. Some surprisingly kick out quite large amounts of bass given their small proportions.
Given that almost everyone has a smart phone these days, it also opens up the possibilities to play all kinds of music on the go. This bundled with new technology and more powerful batteries makes the modern portable speaker a key bit of kit to carry on your travels.
