Simple is good Bluetooth connectivity is a good thing to have. And if your current receiver doesn't offer that feature, you'll be happy to have this marine-rated Bluetooth universal receiver from Wet Sounds. Easy to set up and use There's nothing complicated about the WW-BT-UR, which is kind of refreshing, really. This compact device gets the signal from your Bluetooth device and sends it to any radio with an AUX input or any amplifier with low-level inputs. You control everything - volume, track selection, play/pause - from your device. Indicator lights inside the translucent case let you know what's going on. The blue light indicates Bluetooth pairing status, while the red light indicates amp status. Made for the outdoors The WW-BT-UR mounts pretty much anywhere and it's made for outdoor use, so it'll stand up to pouring rain or pounding sunlight. And it's battery-friendly - if the music pauses for more than 10-20 seconds, it'll turn off your amp until you wake it up again. Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles .
