Got a new pair Iems , the CKR-9s and im currently burning in with pink noise and logarithmic sine.
 
I have always looked at the specifiations on the box without ever knowing what they meant........
Can someone Please explain what they mean to me?

I can explain "Driver" and "Frequency Response".
 
Driver: does the IEM use balanced armature drivers or dynamic ones?
See this article: https://brianli.com/in-ear-monitors-balanced-armature-drivers-vs-dynamic-drivers/
 
Frequency Response: at what sound frequency range can the IEM produce?
The human ear can hear sounds between 20 and 20k Hz.

I suppose u misunderstood the question.
 
Dual BAs are tuned as 1 full range and one bass........
 
How about for 2 dynamic drivers?

Unlike other multi-driver products, the CKR9 is not using 2 drivers for different frequency ranges. It's got them set up against each other in what the company calls a "dual phase push-pull" setup.
 
Also keep in mind that in the world of headphones, specs have less connection to real-world performance than say, a computer's spec may suggest its capability.

Any idea what the maximum input power suggests?
Does it mean that if I use it amped I would risk damaging it?

And also what does the output sound pressure level indicate and how does it affect the iems?

I thought that the audible frequencies change according to age ?
Because I can hear an annoying high pitched sine coming from my WiFi repeater which my younger siblings can hear but not anyone else above 30 years of age.
