vivo published a teaser video for its first noise-canceling TWS buds called vivo TWS 2. The video is mostly about the design of the buds and confirms the announcement date - May 20. The TWS 2 will adopt an in-ear design, quite similar to the AirPods Pro but with shorter stems. There's also a dedicated button for the active noise cancellation and the case looks a bit bigger than before suggesting longer overall battery life too. As we already mentioned, the pair will be announced on May 20 but the actual sales will begin on June 1. Source (in Chinese)
