And everybody on this thread
Actually everybody ear is made differently...
When a loudspeaker play music, the treble energy, and some upper mid energy is losts which is restored by our ear and received on our eardrum and then signal is sent to our brain.
But as all ear canal and pinae are not the same, some may get more treble and some may get less.(this causes peaks)
Eardrum, has stiffness which can be be considered as impedance and this impedance is for only some frequencies, making dips in frequency response.
Brain, well is a complex topic, it needs training and it get used to certain sound and make itself believe that this is natural...
Earphones and iem are way near canal and ear pinae or our external ear structure doesn't contribute anything and because of too much near to canal, treble energy is not reduced(even if tuned) creating peaks and unwanted dips on treble range.
That's why I suggest equalise any iem you get in your hand, listening to frequency tone samples and frequency pink noise samples.(every freq should same)
Once you create a perfect pink noise from an iem, listen to the music from eq profile.
It will make them more comfortable and longer listening with natural presentation...
But story doesn't end here at all.
The story actually starts here
You all would be thinking that if we create flat response for all our iem, they all will sound the ****ing same..
Hang with me everyone, and in the end of this article, you would be surprised.
Well all the transducers or driver are made differently. For example
If
@mbwilson111 and
@B9Scrambler gives an exam, score the same....this doesn't means they both are the same people(until or unless, they planned it).
They have different characterstic, different feelings etc.
This is with driver, crossover etc.
Driver specs and characteristics can alter the decay, distortion which will make the sound still way more different than other by a big margin.
Crossover components will color the signal also.
JBL t100 sounds treble rough and sound magic sounds treble smooth after EQ
