Outdoor bluetooth headset

This water-resistant Bluetooth® headset is designed to keep you secure and stable in any situation. Use the Expand Boom headset to make headset-to-headset calls, take hands-free phone calls or listen to music from your smartphone. No matter what the situation, you'll always get crystal-clear, natural sound. Designed to be water and sweat resistant, you won't have to worry about whether or not to keep your Expand Boom headset on your head when the weather turns nasty. It's the only Bluetooth headset in its class that offers such water resistance. Bluetooth 3.0 technology allows you to engage in a four-way intercom conversation over a range of up to 900 meters. Advanced Noise Control™ mitigates interference with outdoor environments and allows you to differentiate the volume of each audio source.
