The Hercules WAE Outdoor 04 Plus Bluetooth Speaker is designed for riders! It's perfect for experiencing all of your rides with even more intensity, accompanied by your favorite music. It's the ideal companion for getting psyched up or training. IP66-certification means it resists water, and provides total protection against dust, sand and mud. Reinforced rubber end-pieces provide shock-resistance. You'll hear clear, very powerful sound for optimal audio rendering in outdoor conditions (in the wind, on the street). The WAE Outdoor 04 Plus is a single-unit 2.0 speaker with a passive decompression driver. Featuring Bluetooth 3.0 A2DP wireless technology, this speaker is compatible with Bluetooth devices including telephones and smartphones, tablets, and computers (Windows Vista/7/8, Mac OS X). You can enjoy more than 12 hours of music on a single charge. For added versatility, the WAE Outdoor 04 Plus can be connected to two Bluetooth audio sources at the same time - you can switch from one to the other incredibly easily. Onboard controls include volume up and down, next and previous tracks, pause and play. There is an on/off switch and auxiliary line input for direct connection to your audio devices. A USB charging cable is included and this speaker is compatible with 5-volt micro-USB chargers. There's a secure hoop for a wrist strap and a standard-size screw thread for easy mounting (examples: bike mount, tripod, suction cup mount, etc.). A custom Android and iOS app is available for your smartphone..
