Image © KEFThe KEF Mu3 true wireless earbuds deliver a balanced, pleasant sound signature in a stylish, comfortable design, with solid battery life and IPX5 water resistance. While they offer adaptive ANC and wireless charging, their feature set is lean—lacking aptX and multipoint—and their noise cancellation and call quality are only average for the price.
