Freq response, 1Hz-20kHz?
OMG!

And 2 sensitivity ratings, one for each driver....haven't seen specs written this way. And pretty high I might add.

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?

Yeah sure, I am not disagreeing that fact. Though being a good IEM isn't about having the best of the extremes. Liek I said before, even if it can do 1Hz to 40kHz, It won't be a good one if female vocals sound like males and pianos sound like they have pillows stuffed in them.

Well, technically, the spec about the sensitivity is correct. However, that is only applicable in the real-world when the 2 drivers are to become two separate IEMs. When those two drivers work together in a single housing, exiting the same sound tube, the real value would be a single number.

Having two numbers like that makes the specs seem more spectacular than they really are.

Supposedly they are less prone to tangling and they are easier to untangle if they do.
