Tanga offers the Urge Basics Soundbrick Bluetooth Speaker in five colors (Blue pictured) for $34.99. Coupon code "BRICKSAVE" cuts the price to $31.99. With free shipping, that's the lowest total price we could find by $2, although we saw it for a buck less just over a week ago. It features a microphone, up to 80 hours of usage per charge, and Bluetooth 2.0.
