Anker's naming strategy is a little confusing. One day the company was using "Soundcore" for its audio products, the next it introduced the "Zolo" sub-brand for its Liberty and Liberty+ true wireless earbuds, and finally it seemingly went back to Soundcore for the Liberty Air. But there's now a new Zolo branded product, which is an upgraded version of the original Liberty, still costing $99, but with one massive improvement: an 8-hour battery life on a single charge, and a bonkers 100-hour battery life with the charging case.
