Seal won't change how much air pressure in the lower region the iem pumps out, it is why bass doesn't change In measurements regardless of insertion, insertion can only change 2nd wave resonance

Actually Phil from Cosmic Ears did this experiment before, he said that seal could affect the bass dramatically though it doesn't really impact the treble.
His post can be found here
How can you say that for every iem? Insertion depth doesn't affect frequency response is what you're saying? For instance, if treble is attenuated, that is the same as bass being boosted. It might graph as a drop in treble, but at the equivalent axis point that is the same as the opposite bass being boosted. Can you link to some of this data? I'd like to read it to see what you are referring to....
Are we taking into account seal here? As a rule of thumb the deeper the better the seal and that generally brings bass perception up.
YES. Shallow insertion made the earphones sing. They aren't completely bass dominated anymore, but juuust right. Bass is boosted but nicely so, and indeed, it doesn't make the midrange sound heavy. As a matter of fact, acoustic music doesn't sound as if it had any bass boost whatsoever. Treble is far more prominent now, although from what I've listened, the headphones are more midrange oriented than treble oriented.
But in a good way. There's no sibilance, midrange isn't piercing or harsh or too in your face. One single word can define the sound now - smooth and mellow, but detailed when it has to be. Now I understand what everyone is listening to - they are extremely likeable earphones. While my beloved ER-4S need some time to get used to (especially with their bass response) and they can get aggressive with sibilants and such on some recordings, the MH1s are just enjoyable all the time.
That's the good thing.
The bad thing is - after 3 or 4 minutes of listening one channel dropped in level. This is the 2nd time this has happened. I suppose that since I took a bath before, humidity is blocking the filter or the vent. This has never happened before with any other headphone I've owned. And yes, during the morning everything sounds fine.
OK, so it's a good IEM.. but does it also have to have sort of a diva-ish behavior, too?!?!
I ordered two more for friends and one more me as a backup.
Now as far as the adapters, unfortunately the info on ebay is not clear so any input will be great do you think the following will work? (they look like they should work but....)
which website did you buy the mh1's?
