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...

I will wait around a while this morning for someone to answer my Pop Quiz correctly. Then, if the correct answer is not forthcoming I will reveal why tiny bowl 🍲 acoustic resonators work in a room with headphones. Fair enough? For those who did not win this time around or chose not to respond take solace in the fact there will be other pop quizzes. 😛
You mean besides me and mahgister....I hope you weren't up too late packaging up our prizes!
I am curious to say the least, because I cite an article in science establishing the fact that the ears resolution of sound is a fraction of an atom...This is done by an organ that is solid but act like a fluid with ciliae adjust to frequencies perception to this level of accuracy: the tectorial membrane, discovery published few months ago... It seems the judge has not read much of my post...But we know the judge :) it is a friend and friend are bad judge it seems …


Beside of that the antenna of the body extended this resolution power of the ears to a greater extent than what seems possible...Than any modification in the acoustic of a room may be perceptible to an extent that was very difficult to understand before this discovery...
