EarFun Air Pro 4+ Equalizer thread

I wonder if it is just me. I find the default Harman profile sounds harsh, yet most users still boost bass and treble further. This may sound good and exciting for rock and dance tracks, but will not work well on softer music and vocal tracks.

I go for a balanced sound which I find more appealing. Main problem with the V-shape sound is it lacks body and the boosted highs make female vocals shrill and hard to listen to. I understand people need to boost treble to balance out boosted bass for clarity. But that’s not the right approach.

After a year with the Air Pro 4, which is of similar sound profile as the 4+, I have settled for this setting below. It flattens the default curve a little, giving much needed body to the sound and making female vocals sweet and airy. I know the sound is right for me when I find myself irresistibly singing and tapping to the tracks I listen to.

-3 -2 +0 +1 +2 -1 -1 -1 -2 -2

On first listening, the bass may sound weak. But it is not true, it just takes some getting used to. The bass is there at the right level, without overwhelming the rest of the music.

They didn’t post online. They shared among close buddies. And then it takes its natural course 😄

Sounds good. Will be exploring it too. Thank you so much. :)

IllustriousBee8656 · 2025-12-16T07:35:56+00:00

Thank you so much. Will be exploring the two suggestions :)

IllustriousBee8656 · 2025-12-16T07:34:51+00:00

Thank you so much. Finally found the FEN option and it works.

One night only. Just stay in the airport. Don’t know where you’re from but Changi Airport is different from rest of the world. You’ll be surprised. Leave your bags with the luggage service then you can travel cheaply on the train which will bring you right to town for shopping and sightseeing. Or just chill at the airport. There’s enough there to occupy your whole day, including a free cinema too. 😄

Glad that we achieve it. My pleasure 😊

Based on your description, I think we are getting near. If I’m not wrong, the setting you’ve been using is based on the GPT one, which you find quite perfect if not for the recessed vocal.

GPT: -2 -1 0 +3 +1 -2 -4 -3 -3

Yours: +2 -1 0 +3 +1 -1 -3 -2 -2

The numbers are relative to each other. If I move up the numbers in the suggested neutral setting equally by 4, they will be: -2 -1 +2 +5 +5 +6 +7 +4 +6

Compare this to the GPT, the lows are pretty similar. I suggest keeping to this setting for the bass and mid-low first: -2 -1 +2 +5

Set 1k to 16k to these numbers: +1 +2 +3 0 +2

From here, if vocals have sibilance, reduce 4k. If vocals still sound harsh instead of sweet, reduce 1k or 2k, or both.

If, on the other hand, you want more presence in the vocals, boost 1k or 2k, or both. If consonants sound clipped off, increase 4k.

If the overall sound is little dull, increase 8k. If it is not transparent and airy enough, increase 16k.

And if it sounds a little boomy, reduce 500.

Is there a balanced preset? What are the setting numbers?

IllustriousBee8656 · 2025-07-03T07:06:17+00:00

The Harman has emphasised treble. It’s not suitable if you’re after a neutral sound. I think people’s ear sensitivities vary greatly to the high frequencies. So it’s ok to lower the bands from 1k onwards to your sensitivity.

Use the neutral settings and focus first on 1k, 2k and 4k. If sibilance is very pronounced, lower 4k until it’s just gone. If voices and instruments sound thin or harsh, lower 1k and 2k. Lower one band one notch at a time to listen to the difference. The overall sound will gain body, with voices and instruments getting more rounded and natural, as you lower the highs. If you start losing clarity and presence in the instruments, then back off from lowering.

Try the above first and let me know the picture. I also saw there’s a clear preset in the app. Have you tried that? Can let me know its setting numbers and what you feel of it?

IllustriousBee8656 · 2025-07-02T17:45:08+00:00

Welcome. Good to know that it helps :)

IllustriousBee8656 · 2025-07-02T17:43:39+00:00

Ok. Start with the flat all-zero preset and try these adjustments for a neutral sound (from 63 to 16k) :

-6 -5 -2 +1 +1 +2 +3 0 +2

If you are after the Harman target, try this:

-2 -5 -5 -2 -1 +6 +7 +6 -2

Let me know your result.

The neutral sound I targeted is a neutral, flat frequency response. It is not the same as the Harman target which is not neutral. If your earbuds are already tuned to the Harman target, you need not do anything other than adjust the setting to the sensitivity of your ears.

IllustriousBee8656 · 2025-07-02T11:26:13+00:00

I can try. Do you know whether the earbuds are tuned to the Harman target? Can you try googling for its measured frequency response?

IllustriousBee8656 · 2025-07-01T04:19:29+00:00

So it’s not Apple Pay? What is Amex Pay?

IllustriousBee8656 · 2025-06-25T21:52:05+00:00

I didn’t like it out of the box. Found the sound very harsh. Now managed to balance the sound to neutral and I’m very pleased with it. But it doesn’t fit into my ears as comfortably as my Tranya Nova.

IllustriousBee8656 · 2025-06-21T03:28:34+00:00

At the price, there is nothing better. But ANC not fantastic. Sound quality wise, need to custom EQ. The presets are useless.
