How does it function WiFi for earphones ?i.e. connection on the same household WiFi or phone wifi or budd wifi ? It's too early , but can one speak of multi-point WiFi : this 'buds' with more devices ?
If WiFi is not used, is Bluetooth gor this device multi-point ?
The earbuds use Wi-Fi for audio transmission only when connected to a compatible smartphone that supports this feature, such as the Xiaomi 15 Ultra. This Wi-Fi connection is not based on household Wi-Fi networks but is a direct Wi-Fi transmission between the phone and the earbuds to enable high-speed, lossless audio streaming. The Wi-Fi transmission is off by default and must be enabled in the phone's Bluetooth settings. It works alongside Bluetooth but is not a replacement for it in terms of device connection.
Regarding multi-point connectivity, the earbuds support dual-device connection via Bluetooth, allowing them to connect to two devices simultaneously. However, the Wi-Fi feature does not imply multi-point Wi-Fi connectivity with multiple devices. The Wi-Fi function is specifically for enhanced audio transmission quality with a single compatible device.
In summary: - Wi-Fi is used for high-quality audio transmission between the earbuds and a compatible smartphone, not through household or phone Wi-Fi networks. - Bluetooth is used for device pairing and supports multi-point connection with two devices. - Multi-point Wi-Fi connection with multiple devices is not supported.
