this is the software that you use on your smartphone for my Audicus Omni Series 2; Philips has their own similar software, all modern ones do, it becomes easy after a bit of practice
They have one setup called ’Live Music’ which I use when listening to music in an audience or listening to my system.
I used this while considering Philips from Costco

My Audicus/Android phone use both the mic and the speaker of my hearing aids for phone calls, so I can leave the phone on my desk and walk to another room, and the person can hear me, with some, you might hear, but it needs the mic in the phone for them to hear you, and you left it in the other room.
