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...

The discovery I speak about was not about the sensible state of a S.G. … I consider with you that electronic components are very sensible to micro seismic influences for example...

The realization this scientific discovery made me conscious of, are the nature of the conditions required for a better synchronization about the S.G.

Is the S.G. best synchronized between themselves without any modifications? or best synchronized with some modifications, like with some stones or crystals linked to them ?

In my experiments my S.G. are best synchronized with the modifications that alters the identical structure a bit...

I dont pretend to any discoveries on my own, but i make some observations that are new about my S.G. Thats all...
Sorry, the “synchronization” of the Schumann generators doesn’t make sense. If it doesn’t make sense it’s not true. It would be like trying to synchronize some clocks in the room to all give the same time all the time. Since the accuracy/precision of the Schumann frequency devices appears to be an issue with them, then I’d say the pathway to the stars is by obtaining more accurate generators and isolating them. You may have to apply damping as well. I suspect your imagination and or your English translation might be a possible culprit in this. 🤗
