The WiWU O201 is a pair of true wireless open-ear earbuds with over-ear hooks that leave the ear canal open, combining 4-mic ENC for calls and about 36 hours of total playtime with AI translation in the Voitrans app for iPhone and Android. It suits travelers and business users who take calls and talk across languages on the move.
Who the WiWU O201 is for
Talking across languages: The Voitrans app offers simultaneous interpretation plus face-to-face, call, image and audio-video translation, along with an AI voice assistant.
Calls on the move: Four microphones with ENC call noise reduction filter wind and background noise, so callers hear your voice more clearly.
Staying aware outdoors: The hooks hold the speakers just outside the ear canal, so street sound stays audible, and directional audio limits what people nearby hear.
Long workdays: WiWU rates about 8 hours per charge and 36 hours with the case, which charges over USB-C with the included cable.
Skip it if: you expect unlimited free translation; the Voitrans app is free to download but sells in-app purchases, and translation draws on app credits.
