The VAUX Portable Speaker is on sale for $39.99. This is the second lowest price the VAUX has ever been. The only time it was priced lower is the one time it was $34.99 during Black Friday. The VAUX Speaker essentially turns the Amazon Echo Dot into a portable speaker, like the Amazon Tap. You slide an Echo DOt into the top and connect it to the VAUX using the included cables that get tucked away behind an access door on the rear. The VAUX greatly improves the Echo Dots sound quality and provides up to 6 hours of portable use thanks to its rechargeable battery.
