We regularly get emails from companies telling us about all the deals they have planned for the week, and today we got word of all the big year-end sales Anker is running on Amazon before 2019 is through. One deal in particular caught our eye — Anker’s excellent ZOLO Liberty True Wireless Earbuds that normally retail for $80 are on sale this week for just $49.99. At least, they’re SUPPOSED to be on sale for $49.99… but someone made a big mistake and also added an extra $20 coupon to the Amazon page!

This accident drops Anker’s awesome upgraded AirPods rivals to just $29.99, which is an absolutely insane value. It’s definitely a mistake that will be corrected soon though, so grab them at this price while you can and Amazon will have to honor it!

Here are the highlights from the product page:

• Graphene-coated drivers: Produce precision oscillation for superior sound across the entire frequency range.
• Truly-wireless headphones: Let you listen to your favorite tracks with Bluetooth connectivity, so you won’t be held back by wires.
• Bluetooth 4.2 interface: Enables simple wireless pairing with your Bluetooth-enabled device.
• Rechargeable battery: Offers up to 3.5 hours of playtime on a single charge, boosted to 24 hours with the included charging case.
• Sweat-resistant: Provides protection from sweat, so you can easily wear headphones while working out.
