Lightweight. Durable. Loud. The BRAVEN Ready Solo™ is our waterproof Bluetooth speaker prepared to take on the most challenging outdoor activities by your side. An extended range driver and all-direction subwoofer encased in a shockproof thermoplastic housing and aircraft grade aluminum grille produce custom tuned audio with beautiful highs and deep lows. The best part? It lasts for 12 full hours. The Ready Solo has an integrated ¼” thread mount and included action mount that secures the speaker to bicycles, outdoor vehicles and most GoPro compatible mounts. It even stands up to the the most wet, dusty and rugged environments with an IP68 water and debris-proof certification that thrives even in a 30-minute dunk in up to one meter of water. Use the noise cancelling speakerphone to make calls, use voice control to give commands to your mobile device or charge your smartphone from the USB output port drawing power from the 2200mAh battery bank. Pair any two Ready Solo outdoor speakers together using BRAVEN's highly-acclaimed TrueWireless™ Technology for a powerful, immersive left and right stereo experience.
