That said, as a programmer it annoys me I can't properly control the firmware. If there was a way to do the same, IE increase the hear-through volume above the "real-world" level, I'd even risk installing counterfeit firmware. If I understand properly how they work, it would just be increasing one multiplier.

Its a bit clunky, but I think the reach is much higher as even people without access to healthcare may have an android phone and a pair of headphones.
This has many uses, works great as a baby monitor.
