The Aud Mini Smart 6 [$29.99] is one of the best finds of the year. Slim and compact, this portable Bluetooth speaker is as small as the iPhone 6 but delivers big sound. Its small size makes it easy to carry by hand and it can also be clipped to bags or purses with its carabiner. Aud Mini Smart 6 works with a super easy app that lets you pair your devices, stream music wirelessly and listen to FM radio. Don’t under-estimate the awesomeness of having an FM radio. Additional features such as its rugged splash-proof design, hands-free calling and a panic alarm make Aud Mini Smart 6 a great on-the-go speaker. Clip it on your backpack and hike like a captain. It’s the best $30 device I own.
