Is the db level measurement for earphones the same as standalone speakers\sound sources? Because part of the 'sound'(waves) are not transffered solely through air, like most standalone speakers... right?
I'm a non believer, AND it's very hard to dispute a proper double blind test
Although... there's no doubt that the price and visual aspect of the packaging affects the psychological 'value' of the product to the listener. Since SQ is a very subjective experience, would you say that the improvements caused from these aspects (psychological increase of perceived value from the price and visual packaging) is a valid improvement of SQ?
