Same here. 5 is too loud. Even before I tried noisy situations, I noticed more noise detail than before (even with my moderate hearing loss), such as the creaky noises in my stairs, or noises outside.
For speech in noise, these are head and shoulders above everything else I’ve tried. The difference is marked. On a walk on a sandy/gravelly surface in a rather large crowd today, I could hear conversations in front of me and behind me very easily. At lunch at a picnic table with a lot of people around, hearing individual voices was pretty much effortless.
It’s not perfect – and I wonder how this compares to the experience of someone with perfect hearing – but after only one day, this already seems incredible.
To answer @SpudGunner 's question, I try to keep the “Brain” on me, because I want the potential processing power to be available – I guess I’ll have to try turning it off in a noisy situation to see what a difference it makes.
The brain communicates with the earpieces through some sort of proprietary high-speed protocol (because bluetooth is too slow). Streaming from a phone occurs through the brain which uses regular old bluetooth (not sure whether it’s bluetooth 5 or bluetooth LE). The app is pretty rudimentary and mainly allows volume adjustments, a change to a different program (noise or music) and muting. It also shows the battery level for the earpieces and the brain.
On the down side, … I can hear some hiss in a quiet environment, and sometimes there are some weird effects of sharp transient noises (water from a kitchen sink faucet hitting the stainless steel bottom), but (finally!) they appear to do what hearing aids should have been doing all along.
The hearing aids themselves are larger in order to accommodate those larger non-rechargeable batteries.
I’ll keep testing.
