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...

Recall I have two usb Schumann devices the size of your little finger. The way I figure it the shungite doesn’t do anything, heaven forbid, the mass of thin shungite 2x3 plates will lower the resonance frequency little bit on the VERY elastic suspensions I have the usb dojobbers on so it’s all good! 🤗 🤗 🤗
What are the dimension of your usb S.G. by curiosity?

If I recall it is the same as mine ….ok.... I figure it out...


In my experience of the thing the S.G. is like an enhancer of my stones in the acoustic space....No explanation here I just try to convey my impression...
I’m not 100% but IICR you have Blue USB devices from Hong Kong. I have the Blacks. There are the size of a USB flash drive. Is that true or do I have to eat more fish? 🐟
No please dont eat too much tuna! it is very good but a bit contaminated...

Yes I had 4 usb from hong kong and 2 from china + very bad power supply I throw to the sea.... Oups in your tuna I think.... :)

They truly enhance the golden shungite effect in my audio grid... Without my stones the effect of the S.G. is way less amazing...

Perhaps placebo effect, but for the last 3 months I sleep with one at my bed head...The sleep is more deep, less disturbed by the crimes committed in a previous life... :)
You can tune your system. You can tune a piano. You can even tune a car. One thing you can’t do is tuna fish. 🐟
