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...

What say we open the discussion up to similar materials, you know, carbon fiber, graphite, carbon black, graphene and any other carbon-based audiophile stuff? I couldn’t help notice you asked some very good questions regarding graphene in an OP earlier in the year.

Don't forget polyaniline, Na-MMT, titanium dioxide, bentonite, aluminium oxide, silicon carbide...
When I mentioned my favourite crystals, I thought you might pick up on that.

Thanks whostolethebatmobile I note that...


By the way our experiments are different, we use stones and crystals, mine natural, yours artificial, it is interesting for me to learn about your experiments...

Just a word about my use of stones,rocks, and crystals...
I put them all along the way from my gear to the electrical central panel of my house...(for example tiles of shungite on top of the electrical central panel of my house made miracles to the sound) each rocks act his own way, I listen to decide which is his way...


The minerals that are on my gear or near them are connected by cables with one another with thin copper cable (hairlike), all is linked to magnets placed on 6 volts or 1.5 volts batteries (A dozen). This grid change the image and sound to my liking, ...I treated all my room at low cost by trials and errors with my ears, and added many Helmholtz bottles and 4 Schuman Generator tweaked with minerals, and cabled with some home made antennas...I use my ears and modify my gear in a process that gave to me more and more quality...The minerals are the costly parts...If I add all costs...The last result is so shokingly good I dont believe it myself...It is the tweaks I made on my cheapest headphone that is now the best I ever heard... Fostex TH-7B...I decide to post this miracle and wait for some others to describe to me their own miracle...I thank you for that...The experience of one inspire all...

Good on you Mahgister. You are way ahead of the average audio enthusiast. I am lucky that one or two generous and very smart people helped me realise what could be possible. I have also conducted my own totally different experiments in my laundry. I stumbled onto some extremely effective and low cost solutions.

whostolethebatmobile,

I suspect we’re not on the same page. This is not my first rodeo, cowboy. I thought you would pick up on that. 🤠
