As I mentioned earlier, that spec is frequency dependant it reaches 37db at 1000hz where the spec is taken, gets better above and worse below. This is an independent measurement of the se846 from innerfidelity. Notice where it passes 1Khz. If olives, it's spot on, if not it will actually get better with them. My guess is that it's not and the tips used are flexing a bit, allowing the entire phone to very slightly react at 200hz relative to other frequencies. Just a guess.
