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...

Nah. Boo ... 

Copper tape is just copper tape. Copper on one side and adhesive on the other. You can buy it at hobby and crafts stores.

Oregonpapa, actually it’s not just copper tape. Are you pretending to be dense? It’s a whole concept, an IDEA. MY IDEA. But I’m not going to explain it to you or argue with you. Because you wouldn’t understand anyway. Too many Dean Martin records or whatever. You’re on notice, though. All of you knuckleheads are.
Somebody put crazy powder in your blue plate special?? Anyone can use copper tape for any purpose they wish without fear of legal retribution within the limits of the law. I really don't think taping it to your speakers and windows qualifies as an illegal act or (ridiculous) patent infringement. 

I really value your opinion. 🙄 Actually, he was stealing all of my ideas. From crystals to Schumann frequency generator to unused wall outlet covers to window foils. You are not smart enough to think of it by yourself. That’s what China does, and Russia and North Korea, they steal it.
