Solved: how to get real-time bluetooth device audio monitoring on iPadOS | iOS | Android - the SabineTek S610 SmartMike+ bluetooth lavalier microphone.

Being that I  sometimes have the inclination to speak my thoughts out, freely, in public, 

I like to have audio monitoring going on, with a microphone and earphone | earbuds. 

Being that I have upgraded my tech to newer devices, the wired headset | earbuds paradigm is being deprecated, for the sake of adoption of wireless and bluetooth protocols for device audio outputs, rather than 3.5 mm (1/8 inch) TRRS (Tip Ring Ring Sleeve) - "headphone | mic" combos, such that we'd come to know and expect of our audio inputs and outputs for our mobile devices. In lieu of the deprecation of 3.5 mm audio jacks in devices, USB-C ports have taken the place of the former audio jack / port, and now, data, audio, and video information can be sent out, or received, in devices and in peripherals all through one high-speed port. There are many makes and models of USB-C [Thunderbolt] hubs available on internet retail sites, such as Amazon and Walmart.

One of the critical issues that had come up, in the context of Apple's device upgrades, over the past couple of years, or so, in this scope of audio jacks and inputs and outputs is that there's no official Apple USB-C earbuds headset available, and my personal favorite, the Apple in-ear headphones had been removed from the Apple main site (although I'd since discovered that other retailers, mostly academic institutions and universities, are now selling the in-ear headphones that Apple used to carry).
