The TOLV is Sudio’s second truly wireless model and it has improved features that gives it a big advantage when compared to its predecessors. It has Bluetooth 5.0 connectivity which allows each earbud to be connected individually. That means that the earbuds can also be used one-sided, like a wireless Bluetooth ear set. In addition to that, the earphones only weigh 4.5 grams per earbud. It also comes in a redesigned portable charging cradle with matte rubber finishing.
