Jabra via eBay offers its refurbished Jabra Elite Sport Bluetooth Headphones with Heart Rate Monitor in Black or Gray for $79.99 with free shipping. That's $10 under our August mention of a refurb and the lowest price we've seen. (It's also $140 less than the best deal we could find for a new pair now.)

These earbuds feature four and a half hours of talk/music time on full charge; the older model only had three hours. (The portable charging case gives you an additional nine hours of run time also.) 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.
