I wish I could only hear the music through my bluetooth speaker and not my ringtone.

I have an iPhone SE and an Oontz Bluetooth speaker. I play podcasts through my blue tooth when I go to sleep. This isn’t a problem on workdays because I wake up before my ‘do not disturb’ settings open up. But when I take random naps and listen to music or something there is always a chance the phone will ring.

I’ve tried everything. Even turning the off cellular data and using Wi-Fi. I think it still rings no matter what I do. Turning the ringer off etc.

I’ve looked for hacks on the internet and nothing. So while I’m here I’ll ask Apple a question. Who is using their Bluetooth speaker so that they can hear their phone ring? Because I sure don’t need that functionality. Thank you.
