Ok, here is my take:

  1. Even the same model headphones have different drivers. Even for the same headphones, right and left drivers do not match 100%, so obviously, you can not expect other model headphones to have the same driver.

  2. No, you can not eq a "bad" driver to perfection since "bad" drivers will have audible harmonic distortion and phase mismatches. Those can not be fixed by eq.

  3. There is no perfection in audio, but preferences and signatures are preferred by most people.

  4. You can eq a driver with low distortion and no phase cancelations/mismatches (you can look at freq graph, and if there are multiple dips and peaks, that driver most likely has phase cancellation) You can eq that headphone to your liking and it will sound amazing.

Best of luck!

Subject: Generating Synthetic Data for Human Action Recognition
Hello,

In my master's thesis, I generated a realistic dataset that
can be used for human action recognition (using the Unity engine). The dataset
contains 2D - 3D pose information and RGB videos. I wanted to test the effects
of this dataset on real-world action detection (directly on videosYouTube) when
the classifier is trained with synthetic data in addition to real-data (NTU
120).
I want to use skeleton-based action recognition methodology
(since it outperforms RGB-only methodologies for NTU 120) and to achieve this I
applied a pose estimator to videos from YouTube, our synthetic dataset, and
NTU120 and trained them since I believe instead of using directly sterile
ground truth information of our dataset, I can apply pose estimator and use
those pose informations directly instead of worrying with domain adaptation
strategies.
Question is: Should I have directly used ground truth pose
information of our synthetic data in trainings with real-data, or the thing I
did does make sense? If there is any usage of pose estimators as domain
adaptation methods, I would be extremely happy if you can share the papers when
commenting.
Best,

You don't need one and see any benefits when you get a new dac or amp. Instead get new headphones or bluetooth dac amps if you want to use your headphone via bluetooth.

Instead of all of those you only needed a kph30i and a Behringer uca202 (or apple dongle). If you want Bluetooth, you can keep AirPods and you will be as happy as you can be at this price range.

What it does is, it filters the audio signals in a way that you will feel the sound is coming from everywhere even if you have 2 speakers or headphones. This can be good or bad for music depending on your preference but it is a deviated version of source so your music will not be how artist wanted it should be. Also in some cases artists themselves can release their songs with dolby atmos in mind so in that way you will hear their sound in their intended spatial way as opposed to their intended normal way.
