I never try this little panels behind my ears pinna...
But in my acoustic dedicated room i used wi8th success exceeding my wish a foldable wood screen in two parts with some diffusive/absorbing/reflective homemade surface and devices ...
The soundfield was holographic but using only foldable screen or this device will not replace others system/room acoustics surfaces and devices and disposition etc , it is only a tool ...
Increasing decibels levels dont solve bass problems , nor timbre perception problems ... It only help to hear much of what we have already decreasing crosstalk though a bit mechanically...
i would like to try it for fun experiment ... Thanks
But the sellers dont ship to canada as it is often the case... We are assimilated with Russia.. 😁
Hopefully i dont need them... 😊
