The take-anywhere BTunes 100' Range Bluetooth Speaker from Wolverine is a Bluetooth speaker with a whopping 100-foot wireless range. The signal is able to travel through walls for more than a 60-foot range. This speaker is compact and portable, but affords huge sound with impressive bass thanks to dual 2" speakers and a passive radiator. The system can output a total of 4 watts of audio power.
You can connect your Wolverine BTunes wirelessly to your Bluetooth audio device, or to another source that is equipped with a 3.5mm jack like a smartphone, tablet or CD player. The speaker's built-in lithium ion battery lasts for more than 10 hours, so you don't have to worry about it running out of juice. It recharges in just two hours using the included AC adapter -- or, you can simply plug it into a USB port on any computer.
