Braven BRV-1M Bluetooth Speaker
It’s small enough to strap on a bike or pack and packs enough punch to probably require cranking the volume down to half to avoid disturbing the peace. Even at that, the Braven BRV-1M Bluetooth Speaker has a few extra tricks up its sleeve. A rubberized impact-resistant frame also locks out water to IPX7 standards, meaning it’ll shrug off rainfall, splashes, or even submersion to one meter deep (for 30 minutes) without a hitch. An included strap slips through and around the speaker to make attaching it to things easy, as does the included Action Mount that’s compatible with all GoPro mounting systems. Else, pop open the sealed door on the back side for access to an aux in port, a Micro USB to charge it up, a battery indicator, and a USB output to charge your other devices using the speaker’s 2,200mAh battery.
