The Ultimate Ears ROLL Wireless Speaker drops from $99.99 to $69.99 with free shipping at Verizon Wireless. Plus, the shipping is free. This is the lowest price we could find for one of these speakers by $24. These speakers are waterproof for up to 30 minutes at a depth of up to one meter, have a nine-hour battery life, and a 65ft Bluetooth range, which is more than double the distance of standard Bluetooth speakers. Sales tax is charged in most states.
