so I bought the miles david turbines and I have no ides how to tell If I have a correct fit ad these are my first IEMs
the sensaphonics seal test only works for customs, for everything else, it does not in fact reproduce the 50hz range

Sealed is sealed.
Perception of 50 Hz as being "a little softer" more likely indicates a difference in the actual frequency response of either the IEMs or the individual's ears, as opposed to the dramatic loss of bass experienced with a broken seal.
Neosk: Personally, I do believe that one is more likely to attain a full and persistent seal with properly built and inserted customs, but both styles are perfectly capable of achieving a full seal for the vast majority of people.

As a practical matter, sealed is sealed.
The goal of the Sensaphonics Audio Seal Test is to help users determine whether they have attained a seal. This simple series of test tones takes advantage of the fact that bass frequencies are the first to escape via any air passage. The Seal Test is a pretty basic and straightforward diagnostic tool. It is not a measurement device. Your examples involving fractions of a percentage point are confusing for this reason. While it's true that the bigger the air gap, the more sound is lost (and at progressively higher frequencies), all such conditions = "not sealed" in the context of this test.
Glad you find the test useful.
