I’m on Android, so I used an app called “Frequency Generator” (inventive name) instead.
And now I’m depressed. Not only do I have hills and valleys in my hearing, the signal sometimes pans left and right, meaning my hearing isn’t balanced
I kinda knew and expected that, but this made it all the more real
For now LCD-i4 preset will work just as well, the difference tonally between the two are minimal, if any. The reason being, they both use the exact same geometry of the ear port and the housing. Their difference comes from the diaphragm thickness which affects transparency and resolution.
