Very good recording quality having in mind the size and price of the product... Using it for about a month now, all good except if you put the input level high on recorder and volume little higher the earphones start to generate a disturbing high pitch noise. That is also the case if you touch and put the earphone out of ear while they are operating. The result is this high pitch feedback which can seriously damage your ears! The microphones are impressive, the sounds of headphones part much less.
