Hi, I have a few questions...
I have Earsonics SM3 version 1 (I reviewed it in >> here <<), and I accidentaly played 15khz frequency (using SineGen, you can google this) through my FiiO E5 amp at max volume!
From what I know, FiiO E5 max output is 100mW at 32 Ohm... Considering SM3 is 34 Ohm, it may got a power slightly below this...
Question 1: Is my SM3 okay and not damaged? I heard no difference in sound though...
Question 2: How much input in mW can be handled by SM3 before the drivers starting to broke?
Then according to official websites, SM3 frequency response: 20 Hz -18 kHz
It plays 18khz fine and sound nothing around 18.5khz, but at 19khz and above, I am surprised to heard that SM3 still emits a sound above that... But this time I know it's not the real sounds because it's obviously sounds lower than 18khz...
And at 18khz the volume is very quiet but i started to heard a louder lower notes at 19khz - 30khz, and obviously human ears can't hear until 30khz...
Question 3: Is my SM3 okay and not damaged because of playing this extreme frequency? I heard no difference in sound though...
Question 4: Why I can hear this? Is that because of harmonics? Because it started low again (around 6khz) at 19khz and becomes higher toward 30khz...
Question 5: I dropped my SM3 from around 1.5 feet (around 40 cm) height to a solid floor once... Is my SM3 okay and not damaged because of this dropping? I heard no difference in sound though...
Well I'm sorry if it sounds traumatic when I asks this question... It's because I'm only an university student and it costs me arm, leg, lung and kidneys to buy this (kidding )... And my HD-555 started to sound muddy, maybe because I dropped it already hundred times from around 1.5 feet (around 40 cm) height to a solid floor (or maybe my brain becomes burned-in because of SM3 clarity)...
Thanks for your attention. Really appreciate it... Sorry if my posts sounds funny to you...
EDIT:
I also do this frequency test using my HD-555 (it has a freq response from 15hz to 28000 Hz) and I also heard the same strange harmonics although this time it started to becomes louder / sounds unreal (I heard lower notes) at above 20khz instead of 18khz (SM3)...
So I also have new question... Normal human ears only hears 20hz - 20khz... Is it supposed to have the same loudness? Because I notice the volume becomes quieter past 15khz, and at 19.5kHz I must crank up the volume a lot to heard the sounds (using FiiO E5 + HD-555)...
Am I starting to get hearing loss? But I'm not 70 yet (only 24)... Maybe I listen too loud with headphones?
Or is it actually because of the natural jaggy frequency response of headphones like below?
