I want to make this video public but will first just post it here as as I am not sure how I should title it so that it could make sense.

I would also welcome anyone who thinks I am doing a good job to leave a public comment on YouTube telling about your experience you had so far. Please keep in mind that my “goal” will be only reached if I manage to satisfy all my supporters with a tuning that sounds perfect to them. Right now I still try to verify and optimise my target and maybe improve it even more as I can still hear some differences between the flattened HD600 and my tuning but I am not sure how close I should try to achieve it because even the HD600 can change a lot depending how I put it on, as well as the sound from a speaker will also change as soon as you move your head a bit to the front or back. Just play pink noise and try moving your head slightly or do the same with a headphone and notice how the spectrum will change its timbre if you move the headphone around slightly. The same goes for the Earfun Free Pro, depending on how I wear it, sometimes I twist it to the back to get a better hold which will also change the timbre, sometimes for the better sometimes for the worse, there will always be some uncertainty factor and I am not sure how to deal with this as I want to make it as solid as possible with as little coloration as possible. I think I am already much better than anything else I have heard but I am not satisfied as long as I am not 100% sure it’s perfect now. Or course I cannot ask you to tell me if you still hear errors as long as I haven’t created tunings for your particular resonance frequency. Because you will only get the “right” sound if the tuning is optimised for your particular ear canal. I am confident that my method will work as I could experience it on my own with my 2 “different sounding” ear states. By just adjusting the tuning to compensate for the peak shifts using the same target I could manage to make it sound the same for me in both cases.

Before I take further steps and start investing time into creating tunings for other resonance frequencies I need to be sure to have a solid target, and need to clean the target curve which is basically based on a response measurement which I think sounds correct at the given resonance.

I will try to create all further tunings manually which can be sometimes a bit frustrating as lots of trial and error is involved. I want all EQs to have a similar structure which will allow for additional bass and clarity control, but I cannot verify the results with my own ear anymore and will need to wait for your final verdict which can maybe force me to adjust my target again… a vicious circle as you can see.

But when done well this will basically give me the recipe to be able to offer the “perfect” sound to anyone regardless which IEM and which ear canal length. I hope it becomes more obvious now why I cannot offer this for free and I think 10€ for a sound which is perfectly tailored towards your own ear with further adjustment options to meet your own taste is still ridiculous.

Great job oluv. Will leave a comment on the YouTube channel. It is a shame that earfun free pro doesn't have great noise cancellation otherwise it would be perfect!

oluvsgadgets

The Free Pro 2 has, but not sure I can manage to make it sound as good. I first want to finish these until I start to work on another one.

MerlinMei

There must be some other tws using airoha 1562a which does hybrid -40db noise cancellation, allowing us to save down the EQ and has a decent base sound....

oluvsgadgets

That the EQ remains saved also after power down is probably a bug. On the Air Pro 2 it always defaults to the standard tuning and you can also select the standard tuning directly from within the app, like I would expect it to be. On the Free Pro and Free Pro 2 you cannot revert to default tuning, it is probably a bug but this helps to prevent switching back on its own after power down and the user EQ remains active. Actually the bug works in favour of what I am trying to achieve.

Honestly I don't really think noise cancellation is so important. Just passively they cancel out about as much as my Soundcore Q30's do. So I see no issue, because I mainly listen at home, it could be useful in other scenarios, but in this setting I have no complaints.

It is perfectly clear that everyone has to get appreciation for hard work and efforts. So the 10€ are a no brainer and more than ok. I‘m happy to pay to get that great sound.

MerlinMei

I'm ordering an airpod pro replica from AirReps to see if the EQ can be saved (the sound must be poor....)

Hi Oluv, ich würde auch gerne die neuen EQs für den Earfun Pro Oluvs Edition bekommen. Ich habe aber leider (oder eben eigentlich auch nicht leider) kurz zuvor bereits ein entry level Jahresabo für deinen Kanal abgeschlossen. Ich kann das nicht nur für einen Monat hochstufen, sondern nur das ganze Jahresabo, was mich dann € 80 kosten würde. € 10 finde ich absolut ok, € 20 wäre auch noch vertretbar, aber € 80 finde ich zu viel, das ist ja mehr, als die Earfun Pros selbst gekostet haben. Gibt es eine andere Lösung, paypal oder etwas ähnliches ? Und wo gibt es die App? Im Appstore habe ich die nicht gefunden.

Earfun Free pro tuned by you is so amazing,in spite of its hardware limitations.

Herr.Rossi

Hi Oluv, ist es von der Qualität her schlecht einen externen EQ wie Wavelet zu benutzen? Wenn es direkt funktioniert ist es natürlich besser aber sinkt die Qualität des Signlals dadurch wesentlich? Oder kannst du durch mehr Filter am Ende mehr erreichen? Mit dem Graphischen EQ hättest du ja unendlich viele Filter zu Verfügung. Der Umgang mit einer Datei zum importieren wäre User freundlicher als die etwas zickige Android App. Außerdem wärst du bei der Auswahl geeigneter Inear's nicht auf die Kompatibilität mit der App angewiesen. Eventuell wäre es sinnvoll mit AutoEq auf deine eigene Zielkurve zu nutzen um die grobe Vorarbeit zu leisten. Vielleicht sogar auf verschiedene Zielkurven mit den jeweiligen Resonanz Frequenzen.

Full a no Brainer Really really every Cent worth his Tunings

Haraprasad Sahoo

Am getting peak at 5400 am i a super human, help oluv😢😢

Juraj Bodnar

I think something like this example: http://grafo.sk/app.png - could be perfect and helpfull feature for every headphones. Instead of stupid "Jazz, Pop, Rock,.. " EQ settings. Maybe this could be the main function and also marketing advantage of your own headphones model - "headphones customized to your ear".

reiro

Stupid question but does the new refined EQ just work with the EarFun Pro of the Oluvs Edition? Since that is sold out and I can only buy the non Oluv Edition. Someone enlighten me. Thanks.

Juraj Bodnar

It works also with normal version.

oluvsgadgets

Nicht unbedingt schlecht, kommt darauf an ob davor auch schon ein EQ aktiv ist. Ich mag halt wenn ich direkt im Gerät einstellen kann und es auch gespeichert bleibt.

oluvsgadgets

I will try to create an EQ for every frequency possible but it may take a while. It’s hard to measure even that low.

Martin Lerke

Das Problem bei vielen Leuten auch leider bei meiner Freundin als beispiel, Sie findet die Neutrale Abstimmung langweilig was ich persönlich garnicht verstehe. Hab ihr versucht zu erklären, dass um die Musik korrekt zu wiedergeben ist, eine Neutrale Abstimmung braucht damit sie so natürlich wie es nur geht wiedergeben wird. Ich bin die Earfuns mit deinem tuning einfach gewönt hab mir auch die Sennheiser HD600 mir gekauft und finde sie auch gut zwar nicht perfekt aber ausreichend. Finde die Earfuns mit deinem tuning einfach perfekt, man kann wirklich in die Musik eintauchen ich hör einfach sehr viele Details raus die ich nicht mal mit Standlautsprechern gehört hab. Daür braucht man auch nicht so viele peaks um die Höhen zu betonen so wie bei den Bose Kopfhörern.

Site throws 403 error

Aivis Zolmanis

Advantage ? No way. Have you listened to those new headphones with 360Spatial Cinema THXxx Tru+ SignatureAdapt sound ? What marketing advantage ? Your concept is ridiculous...I have better Hz on my 8K TV panel.

Juraj Bodnar

Sorry I think you didn't understand what i am talking about.

Dennis

Moin, kam die JBL flip 6 schon an? :) bin gespannt LG

oluvsgadgets

Ja! Bin gerade am Testen. Sonos kackt voll ab dagegen und der alte Flip 4 auch, 5 hab ich leider nicht aber Höhen sind echt gut etwas zu betont, aber dafür gibt’s nun einen EQ. Ist sicher der beste momentan in dieser Klasse

Dennis

Uii das gibt es ja nicht das JBL mal besser wird. Und wenn du schon ein JBL Lautsprecher lobst dann muss das was heißen :D Also lohnt es sich noch abzuwarten bis der Preis ein wenig fällt und dann ist die neue Flip 6 echt ein Deal? Auf das Video bin ich sehr gespannt mal sehen was die Motion+ dagegen kann. Danke klingt ja schonmal gut =)

Aivis Zolmanis

I will be thinked that you're the one who's didn't understooding. 😅

Sie sollten Böse heißen haha! Volle KAKE!
