The Good: The Zolo Liberty are totally wireless earphones that offer decent sound for their price. They're sweatproof and include a charging case that delivers as much battery life as the AirPods' charging case. The Bad: Aside from the decent price, they're otherwise pretty generic. The Bottom Line: The Anker Zolo Liberty do just enough for the price to make them recommendable totally wireless earphones. Anker is better known for its mobile battery accessories, but lately it's been making a serious push into the headphone market. The company is selling two new totally wireless headphones, the Zolo Liberty reviewed here and the Zolo Liberty Plus. They sell for $100 (\u00a370 or AU$130 converted) and $150 (\u00a3150 or AU$139) respectively. They're both pretty good but not quite good enough to make you forget about the AirPods or Jabra's Elite 65t.These are noise-isolating buds and, from a design standpoint, aren't so different from Jaybird's Run headphones and Bragi's entry-level The Headphone.The step-up Liberty Plus has a little bit more of a premium look and feel that extends to its charging case. While it's slightly smaller than the standard Liberty's charging case, it has a little bit of metal trim and a higher capacity battery inside so it's a little heavier as a result.Anker says you can get about six or seven extra charges from the standard Liberty's case and 13 or 14 from the Liberty Plus' case. But the base battery life for both models is rated at 3.5 hours. That's not quite as good as the AirPods' battery life.
