I have spent a week of intense sound tweaking by trying to optimise my headphone target and achieving a final usable result creating an EQ for the Sennheiser HD800S which you can find here and another completely new EQ for the HD58X. I also spent extra time trying to fine tune my settings for the UBoom X to achieve an even more faithful sound especially for the studio mode which I would like to demonstrate in this video, but I also tweaked indoor and indoor+ to make all modes sound as natural and and enjoyable but at the same time similar to each other as possible.

As a consequence from all this I also had to create a new compensation for my recordings completely from scratch as recently I had started using new microphones and my previous attempts were just readjusted over time bit by bit based on a very old state. As my headphone target is quite different now and sounds much closer to the speakers, my recordings didn't sound quite correct anymore. Therefore it took me some further days to achieve a compensation which should be much better and much more natural sounding than all my previous ones. Now I can be sure that my binaural recordings sound true and are as uncolored as possible given you listen over a properly tuned neutral headphone. My current compensation has additional correction for my left and right ear separately which also improves the imaging a lot. I had to spend endless hours listening and comparing my recordings of the KH80 to the speakers themselves as it was impossible to achieve faithful results by just trying to match some measurements. It was more or less like tuning an additional headphone but instead of tuning the headphone itself I was tuning the recording to close the entire circle and make the recording of a neutral speaker pair sound just like the neutral speakers if listened over a neutral headphone which again should sound approximately like the neutral speakers. By just flattening the recording it still didn't sound alike and I had to seek for nuances to match 2 different spectrums as close as possible. This takes long and I needed to manually sculpt various areas of the captured spectrum to make it sound correct. Although I can never be 100% sure that I am really correct now, I simply think that my current state of understanding and being able to capture and reproduce sound faithfully and correctly by a speaker or a headphone is much more complete and I start hearing more and more how off all headphones sound despite some bold "True Sound" claims by B&W and many others. Thankfully the ear is able to adjust immediately to a provided sound and accept this after some time and without having a constant correct sounding reference it is close to impossible to tell if the sound you are actually hearing is any close to what was really captured. In my case I can proudly state now that what I capture with my ears is also reproduced correctly by a headphone corrected with my EQ.

More EQs will be coming and I would like to release a new headphone EQ every month just like I had promised long time ago. But as the effort is really high to optimize a single headphone through constant listening I would rather like to concentrate on releasing an own headphone if my quality demands can be fulfilled. The more I am able to fine tune for nuances the better the final sound will be just like demonstrated here with the Uboom X. Although the differences may appear subtle at first, in the end it is just these nuances what makes a "good" sound stand out from bad sound and finding and optimizing for these nuances is where really the effort should be put in and not releasing new products every year just to make money out of nothing.

I thank everyone for their longtime support as without you my search for the perfect sound would have never been possible. I am still struggling every day but at least I can do what I really love doing and I hope my work can also improve your love and passion for music and sound!

God bless you all!

Wish we could EASILY download new eq settings for uboom with a oluv app or online site via our phones. I dont have computer. I have windows but I look out of them and today im cleaning them 😆

DominikReviews

its impossible if you dont know the source code of the windows multimedia app

Can I request the song Ikembot Mo Baby by DJ Rowel sir Olaf next time. I'd like to see how the speaker render that kind of tracks. 😊

Robert Mcintosh

The headphone EQ sounds really good. Almost identical to the monitors. would love to see more over the ear ANC bluetooth EQs

I would love an EQ for the DT 770 Pro 80 ohm

oluvsgadgets

it will be hard to tune as it changes the sound a lot with different position, similar to the HD800S. and treble is very peaky, while the HD800S has just the 7 and 9khz peaks which cause problems, the entire rest is pretty OK

I think that's their job to offer us something usable, these companies are asking a lot of money for their crap. With classic passive headphones like the HD600 etc it is something different, but no reason to equalise some bluetooth headphones which are already heavily equalized from factory, let alone how would the EQ be applied externally? As soon as I manage something decent for the Oluvsone headphone I won't care much about other headphones to be honest.

Robert Mcintosh

I understand your perspective. but some of us live in noisy urban apartment buildings where great ANC is a must. As you say, most ANC headphones have crap sound. The Q30s sounded great with your EQ, however the ANC and build quality was crap. There's a need for a headphone with great ANC and build quality that also has great sound. I feel like there's a good opportunity there

Richard

Ai will reverse engineer that crap sooner or later

Unit variation from at least pad wear is also massive. I've measured four units and some don't look like the same headphone while externally there's no clear difference. I'll measure a dozen some day with a single pad and see if it's just the pads, but I doubt it.

The new Sennheiser 630 something bluetooth headphone (based on the Neumann model?) seems to be acoustically tuned and with EQ support (perhaps PEQ?).

Luka Bošnjak

Nice playlist here and of course so interesting to learn something while listening to music..

Hi, Have you got a chance to test the new Sennheiser headphones? The HD 490 Pro with the mixing pads and the HD 550? I would be curious to know your honest thoughts on them. If any of them are worth it over the HD 6XX or HD 600.

oluvsgadgets

I don’t think any headphone is actually worth it, I wouldn’t have high hopes for any Sennheiser headphone, just a bit more here a bit less there but the typical Sennheiser sound remains.

Robert-Andrei Botezat

Okay, I understand. What about AKG headphones? In particular K-702 and K-612? What do you think of their sound? I heard K-612 is almost dead flat, possibly dull and boring, according to some, which I disagree, but anyway. And K-702 is like a shoutier version of K-612. But it has a wide soundstage.

Robert-Andrei Botezat

But they are pretty easy to EQ to make them sound as natural as possible. Any thoughts on that as well? How to achieve it?

oluvsgadgets

My headphone will be dead flat, not these here. I have the K612 so we can maybe compare these.

Robert-Andrei Botezat

Nice. When will you release your headphone and where we can find them to buy internationally?

oluvsgadgets

I am working on finalising my tuning right now and it will be only produced as a small batch over some crowdfunding campaign. Only if we can get enough funds the production can be realised.

Robert-Andrei Botezat

I see. Okay, good luck with the campaign then! Hope to see it. In the meantime, is there anywhere I can listen to it?

oluvsgadgets

No, not with the current model I am working on. I am still during the tuning process. It’s not that easy.

Alex

Hi

David Drake

Sounds good. Try a a Hivi Swan M300 Mk2 sounds real.

David Drake

Where do I get this song?
