Groupon offers the Jarv Nmotion Sport Bluetooth Earbuds bundled with the Jarv Universal Armband in five colors (Black pictured) for $29.99 with free shipping. That's $17 under the lowest total price we could find for such a bundle sold separately elsewhere. (For further comparison, we saw the headphones alone for $5 less a month ago.) They feature in-line mic and function buttons, Bluetooth 4.0, and a lithium-ion battery. Deal ends November 3.
