I'm not familiar with the Maui 5 speakers but if it has a jack I don't think there will be any problems.
The jack provided has a transmitter for the microphones and works on other non-JBL devices. Apparently, as long as you have a jack, the microphones work just fine!

I didn't manage to connect my mics without the transmitter supplied by JBL but otherwise no problem on other devices if you have the plug with you.
