Audio Pro A28 & A48 - listening test (Patreon)

I thought it could be interesting to compare the small A28 to the A48 as well, as both have a more constant frequency response than the A36, unfortunately I didn't notice that my son mounted the covers upside down for the A28 which was also placed upside down, therefore the change in sound with or without cover is quite strong. I cannot hear the differences through my closed microphones that well. 

Audio Pro will also send me the A38, so we can compare the A36 to the A38, as well as the A38 to the A48.
