PA speakers

Wireless connections are all the rage... but being aware of the risks of overexposure and the electro-hyper-sensitivity (EHS) that can result from it, I want to limit the waves :) I'm looking for a portable speaker (battery and less than 4kg), with a 3.5mm minijack AUX connection, and with a decent and powerful sound :) The BOSE S1 Pro is surely much better in terms of sound quality, but its 7kg puts me off a bit... I have contacted Sony, JBL, Harman Kardon, Teufel... and none of their speakers work without the bluetooth automatically turning on and searching for devices... What I want to avoid. I saw on Galaxus the V205B from Vonyx, and ST040 from Fenton, which seem to be able to work without bluetooth, but I don't know these manufacturers, nor their quality. Are they good? Do you have any other models to recommend? Thanks to you who will read and answer me :)
