How does the Bose app talk to the device? Wireshark can probably be used to analyze it. Writing a simple free software replacement for the bad app could be a fun project and the result will no doubt be much better than their proprietary software.
what options can there possibly be? it uses bluetooth.

bluetooth has reasonable security built in. bose products make use of it.
The BT dump tool can be run on the bluetooth device (eg laptop, phone) and so get access to the negotiated crypto keys oe cleartext version of the comms.
