I’m using the Soundcore 2 via AUX. A really good sound for this small device (and the small price).
If LineIn is plugged, the blue led stops flashing and Bluetooth seems to be off, but it isn’t. It it’s furthermore in pairing mode and there seems to be no protection against unauthorized pairing and connection, no pin-code or hardware-button.
In the manual is written, that the distance has to be less than 1m in pairing mode, but it works also in distance off 10m or to the next floor through reinforced concrete.
What prevents a neighbor to connect to my Soundcore and using the build-in microphone ?
Tested with Samsung S5mini, Huawei Mediapad and Raspberry Pi.
