Yugster offers the refurbished Samsung Gear IconX Cord-Free Wireless Bluetooth Fitness Earbuds in Black for $69.97. Apply coupon code "DNEWSICONX13" to cut that to $56.97. With $3 for shipping, that's the lowest price we could find for a refurb by $40 (outside of the sellers below), although we saw them for $4 less in July. (It's also $65 under the best deal for a new unit.) These water-resistant earbuds feature a 4GB music player, microphone, fitness tracker, heart rate monitor, and rechargeable Li-ion battery with up to 3.8 hours of music per charge. They come with a protective charging case.

Note: A 90-day warranty is included, but it's unclear who backs it. TechRabbit via eBay and iTech Deals via eBay both charge the same shipped price.
