Thank you for pointing this out, according to my research it is the same article. However, one is an offer from a third-party supplier and the other is an offer from us. The product pages do not seem to be linked correctly.
In voice call translation mode, your voice cannot be prevented from being heard by the other party; the device captures and translates what you say in real time, but your original voice is still transmitted. The function translates and transcribes words to facilitate understanding, but does not filter your voice so that only the translation is heard by the other caller.
You can use a headset as a microphone instead of the mobile phone, but to do so, you should use the device's 'Listen & Play' mode. In this mode, the mobile phone captures the audio while the headset provides the translation. However, to use the second headset as a microphone, you may have to configure the device so that it correctly recognises the audio input. Be sure to consult the manufacturer's instructions for further details on the optimal configuration.
