Bluetooth speakers are cool. You can leave them at your desk, put them around the house, take them out to the garden, and still listen to music and audio while you're working or relaxing. This Braven 770 speaker is even cooler because it sports IPX5 water resistance so you shouldn't be afraid to bring it to the poolside, put it next to the kitchen sink, or listen to it while you shower. It also has 12 hours of battery life and comes in a spiffy black aluminum grade housing with nice control volumes on the side.

Braven is brave enough to say that the included 1400mAh battery can be used as a portable power bank at 1A output, but we all know that you're smart enough not to use that and you've instead grabbed a real external battery for your phone, but I guess you can still say that this is a feature. The more interesting aspect is the pairing mode that lets you connect two speakers together as left and right channels.

The Braven 770 has an MSRP of $149. It usually retails around $130 but once dropped to $91. Today, however, as part of Amazon's Gold Box Deal, you can grab it for 50% off the MSRP: $74.99. It only has 28 ratings and an average of 4.4 stars, but Braven speakers are usually above average so you shouldn't be disappointed with your purchase.
