Hello,
I would say that the two important factors that those two exercices reveal are:
1) Speaker placement in your room
2) Acoustic treatment of your room
Those two factors determine the quality of the phantom center that your stereo setup provides.
Headphones eliminate the room acoustics problems, but also substract the ''crosstalk'' and thus eliminate the phantom center.
Acoustic reflections in your room also negatively impact the quality of your phantom center.
So if you would like to improve the quality of the stereo reproducton in your listening spot, place the speakers in a equilateral triangle (with a tape measure, as precisesly as you can) and then add substantial acoustic treatment to your room (that will help greatly with the modal activity, spectral response and RT60).
Hope it helps!

Thank you very much P.M. i figured!, so far what i am working mostly with is my head phones, and maybe its the quality of head phones. I have the DT 990 PRO (250 OHM), and my interface is the standard Scarlet 2i2 Focusrite. I do have monitors the Yahmah HS5 5-inch , but the way my room is set up, its hard to have the equilateral set up as you have suggested. Mostly due to lack of space on my desk and just the room as a whole. So all i have are my head phones. 😭

My pleasure!
As they say '' you have to do what you have to do'': if the only option available is the headphones (and for the stereo imagining all of the headphones work on same principal, no matter the price), then you might want to try the crosstalk simulation software like this one for instance https://goodhertz.com/canopener-studio/
It is also worth mentionning, that the headphone amp on the 2i2 is not exactly glorious, so if you're exclusively using your headphones for mixing, you might want to upgrade that part of the chain with a Grace m900 or swap completely the interface with a Neumann MT48 which has a great headphone amp, amazing converters, great preamps and is very flexible and will work with a lot of your setup iterations in the future.

Listen to the smallest sound you can hear to make it more recognizable

One trick is to turn the speaker/mute button on, and off a couple of times . It can help you pin point where it’s coming from. Plus you wanna make sure your speakers, and listening position are set up right

honestly it comes with just staying consistent

I find that in headphones I struggle a lot with this. But, if I use monitors or even my MacBook speakers it is easier.

My 2 cents:
I mostly use headphones, Sony 7506, Sennheiser HD 400 PRO & more recently Slate VSX

1) Increase the zoom setting in your browser so that the playing area fills to the edges of your screen.
I use 150% (per screen shot) for Pan Girl, optimal value for your setup will depend resolution & size, so experiment with different values. This allows me to better visually calibrate what I’m hearing to the pan position.

2) Use practice mode (available to paid users)

Hi Isildur! I got stuck on Pan Girl for ages, but just stayed with it and gradually improved :) It helped when I learned this game is especially difficult in headphones (my setup). Aah – I'm supposed to be struggling! All good _ For Stereo Field, I ask myself: where are the players standing? Or: how close to the vocalist are these instruments? It helps me more easily hear when the guitars/trumpets etc. are in the middle or how wide they might be spread to the sides. Good luck & stick with it!

Listen with your whole body, from what I experienced it's all about physical perception of space.

Thank you all family, your feedback has been tremendous. Really means alot. It makes me realize i'm not the only one struggling with this. The difficulties, i have had with these two exercises has made me realize it is time for me to upgrade my gear the Scarlet 2i2 has gotten me far enough. Thank you all again. Will keep you posted

@isildur green The Scarlett is fine, really, for your purpose. It's not what prevents you from having an accurate representation of the sounds presented. Better invest in Monitors, or at least, if more volume is what you are after, a headphone amp, or better/more suitable headphones.

I had a really hard time with both of those games in headphones. Once I started using studio monitors, I could really locate the sound.

I’ve been using SoundGym App on my iPhone rather than my desktop, and so, I listen on my AirPod Pros but what has helped has been just a combination of viewing the answers and prior to completion of the games I use the practice feature. When I do listen on my desktop I use my Ollo headphones.

I use headphones and my phone and if I’m having trouble I stick my hand out and try to point to where I’m hearing the sound coming from. Sounds dumb but it helps a lot. Also I use the DT880s which are similar.
