This new SCOSCHE boomBOTTLE+ wireless speaker may be more rugged than even you. Designed initially for on and off-road cyclists, but also backpackers and hikers - essentially all those who know a thing or two about balancing function versus weight - the boomBOTTLE+ packs two 360-degree 50mm drivers and a passive woofer into a waterproof, weatherproof, and bottle cage or cup-holder ready design. Strong enough to pump out music above the sound of the road, mud, and even your heavy-breathing, the boomBOTTLE+ is built to last and packs a 15-hour playback battery. In addition to use on its own to play music, the boomBOTTLE+ can be paired with another for surround-sound or be used as a mobile charging station for several small USB-powered devices. The SCOSCHE boomBOTTLE+ is available now in three colorways - black, gold, and blue - at audio and electronics stores, including Amazon.
