Miracles in Audio, by luck, by good choices,by design or by tweaking...


I owned a low cost headphone for many years, the Fostex TH7B, first version( a new one close version exist Fostex TH7BK), semi-open headphone...I was never completely satisfied by any headphones I ever owned: Hifiman 400, Stax basic lamda, Stax 5 gold,Akg 340,Akg 701, beyerdynamic 990, and T150... Because in each of them with all their qualities I never listen to at the same times, a confortable headphone with natural timbre and voicing, with a good imaging and a realistic soundstage(not too close to my ears)...


For the last days I tweaked this Fostex, to damp his internal resonance I used sorbothane, I put some shungite stones at the exterior part of the cups and I use some Herkimer diamond in the interior pads( 3 at 120 degree) … Now this low cost headphones crush all my others if I sum all his qualities... For example his mids and voicing cannot beat the AKG 340 but among all my other headphones it is the best that is near that mids and it is more confortable, and with longer cable than the 340...His imaging is better and more realistic than the 340 etc etc...It is the same if I compare with the others...


His most important qualities is natural timbre and clear imaging,very precise pinned point accuracy and natural, so clear it crush for that ALL the others to dust...In the French audio circle the reviews were more than very positive few years ago...Diapason d’or and choc Classica...I am not the only one impressed buy the ratio quality/price... But remember that thesae reviewers dont tweak their headphone...The difference between before and after the tweaks are staggering...


Yes Miracles happens in Audio: cost is under 100 American dollars... Few years ago they cost me 50 bucks new... I never dreamed that I will go back to headphones...


I will enjoy your miracles stories of any kind ….My best to all...

Haha. We're probably not on the same page. But it doesn't matter, you're usually interesting to read, and perhaps I may be occasionally.
OK, I’m going to help you out. Here’s a copy of the first paragraph of your OP from April 2019. Hope you don’t mind too much. What I call the carbon connection. Let’s get down to the real nitty-gritty. 🤗

“Cable insulation, graphene, electron flow... how does it work?

From my limited experience with graphene pasted on fuses, it appears to work when painted on the glass only. And I know that graphene painted on the exterior of capacitors can help improve sound quality, presumably by facilitating electron flow to and from the capacitors. I know graphene works on any exposed wire or solder joint. It also works when painted on the insulation of cables. It does not control vibration to my knowledge. Therefore, something crazy is happening whereby the graphene is facilitating the flow of electricity, even when applied outside the insulation.”

I gave up on that topic when somebody helpfully pointed out that electrons don’t flow. And I was told that graphene is only graphite and you can’t paint it on. And anyway it's all snake oil so why bother?
I’m shocked that there is so much disinformation and misinformation in the audio hobby. 🙄
Well I would hate to contribute to any more of that. But graphene does seem to know what you want it to do. Or maybe it just does what it wants. Funny thing is, it takes its time. Like linking segments, or spreading tentacles or something. Please don't try to prove or disprove that technically. And I do think it facilitates signal transfer (safer than mentioning electrons) in metal conductors, merely by being in close proximity.
