If you want to go big in the $299 bluetooth speaker market and looking for a waterproof speaker then the Megaboom maybe up your alley. Plus with its accompanied app always having updated features even sporting an alarm clock its hard to not like this device.

You are out and about with your smartphone and decided to throw a tailgate party. But the sound is tiny. Luckily, UE Megaboom is one heavy sound machine that can last a day long party.

An outdoor portable speaker needs to withstand the elements. Water, dust and drops shouldn't faze it. But there's more to a good speaker than toughness. Sound quality matters a lot, too. The $300 Ultimate Ears Megaboom - which joins the

Tough, waterproof design; Big, balanced sound; Battery lasts 20 hours; Excellent free companion app

Large for a portable speaker; Expensive

I've had a non-wireless speaker dock for a while and love the sound it provides. I've been looking for something comparable that is wireless and doesn't use a power cord. UE Megaboom is perfect. It sounds great, can be controlled from iPhone, and lasts a long time on battery power.
