Jabra via eBay offers its refurbished Jabra Elite Sport Bluetooth Headphones with Heart Rate Monitor in Black for $99.99 with free shipping. That's tied with last week's mention and $150 under the lowest price we could find for a new pair. They work with the JabraSportLife app for iOS or Android to monitor pace, heart rate, and reps and provide audio coaching.

Note: A 180-day Jabra warranty applies.
