This test is a joke. Instead of putting the HA in his own ears, he makes a big show with this dummy called Chris. The “meter” only shows if the sound is still being received. He uses a normal phone as a source with a direct line of sight.
We can all do this ourselves, without a meter.
In the free field, the biggest problem is that the signal cannot be reflected anywhere.
In addition, our body is a big obstacle because it additionally attenuates the signal.
My own findings with my Phonak Paradises:
-
First-year, with Samsung Galaxy S7: When the signal got bad, I had to hold the phone in front of me, or put it in my breast pocket for improvement. Since my jacket pocket is on the left I also changed the BT master to the left HA because of this.
The phone in the back pants pocket was a no go. -
Then I changed to Samsung Galaxy S22: EDIT: It is much better now, but I still cannot keep it in the back pants pocket.
I conclude:
The phone also has an influence on signal strength and range.
I Agree. With the Paradises, I never noticed a problem relaying the signal from the master to the slave HA.
EDIT:
Now I did the test myself:
Outdoor, free field without obstacles, phone horizontally on a wooden pole about 1.5m above ground, 0°C (also freezing cold… 
)
Galaxy S22:
- max. 25m with my head in between the phone and master HA.
- max. 50m with free line of sight between the phone and master HA.
Galaxy S7:
- max. 15m with my head in between the phone and master HA.
- max. 25m with free line of sight between the phone and the master HA
