Ending today, Groupon offers the JLab GO Wireless Bluetooth Sport Headphones w/Mic + Armband Bundle in Black, Blue, or Purple for $29.99 with free shipping. That's $50 off list price and the lowest total price we could find, although we did see it for $3 less in May. It features a range of up to 30 feet and up to eight hours of playback between charges.
