The UM Merlin custom has 4 BA and 1 dynamic but I don't see 5 different sensitivity ratings.
1Hz is bass, but that is ridiculous. An average human can hear only down to about 20Hz, and for special some probably lower. 21kHz is quite high. We can't hear it, but can sure annoy a dog or a cat. The wider the IEM can cover generally the better. However, it's not as simple as that.
The sound of a violin for example, is actually a very chaotic mash of different frequencies, producing one distinctive sound. So is everything in the world like the human voice, foot steps, door knocks, dog barks, flowing water, the click of a mouse, the tap of the keyboard, the hush of a wind, everything. Imagine a single IEM driver trying to produce the sound of one violin, and then add to that a singer, and then a few cellos, and then a piano, and a double bass, and then a clarinet, add some drums and a saxophone as well. See how complex it can be?
we cant hear below 20Hz or above 20kHz..1Hz is bass, but that is ridiculous. An average human can hear only down to about 20Hz, and for special some probably lower. 21kHz is quite high.

but that doesnt mean we wont hear the difference on how frequency below 20Hz and above 20kHz affects what we hear.
