Tanga offers the Monster Turbine High-Performance In-Ear Headphones for $59.99 with $4.99 for shipping. That's the lowest total price we could find by $42, although we saw these headphones in February for $6 less (since expired). These in-ear headphones feature wide bandwidth drivers, all-metal housing, sound-isolating eartips, and more. Deal expires today at 10 pm ET.
