bose 700 on/off while plugged in minijack
While plugged in with the mini-jack, I hear "bluetooth off" (that makes sense), but I can still press the power on/off button, and that significantly affects the sound. It gets a huge boost in midrange when off. They sound totally different. That means really I can't get them to sound OK without battery...
What is being turned on/off exactly?
Also, whatever is "on" (not bluetooth) is it consuming battery?
-- All this with noise cancelling turned OFF (so it's not that)
