Default IEM Modification to reduce harsh treble or high frequencies

IEM Modification to reduce harsh treble or high frequencies

Hey Guys,

Tried this trick with my Creative EP 630, The highs are harsh for me, I didn't wanted to alter equalizer on clip+ as I like the neutral sound from it.

Things you'll need.

1. Micropore Tape । Should be available in medical kit।
2. Scissors or Blade.
3. Any IEM with harsh treble or high frequencies.

Cut micropore tape and stick it to the end of earphone nozzle on top of metal mesh filter, This will act as high frequency filter.

Here is a Pic.

Trying to dampen the driver to reduce its high frequency response does the same thing as electrically reducing the frequency response via EQ.

That said, with such a tiny bit of material in an IEM, I doubt there is much effect from that. The membrane you've added is so thin you can see through it, so most likely its acoustically transparent too. Do you notice much difference?

@saratoga

Yes much difference after applying this tape.
I can say around -4 to -6 db of high frequency is attenuated

Why not just buy iems that don't have harsh highs/treble to begin with?

That would make the most sense.

This seems similar to Phonak's use of different filters to vary the amount of "bass", so if done well, I can understand the principle
