Of course cupping hands improves the gain, like a satellite dish diameter, but it also interferes with or changes some other things like frequency response and soundstage/ambiance. The biggest effect is when the system dynamic range is kind of compressed or when playing at low volumes. My first product was going to be Ortho Ears but it never made it out of R&D. :-)
a crazy free audiophile tweak
i discovered this because I have a block middle ear tube in my right ear.
but, if you place your open palms just behind each of your ears, listening like this vs normally there is a huge significant sound quality improvement
not sure how practical this will be, but maybe someone can invent a pair of add on ear extenders---
funny as it sounds, try it!
