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...

UPDATE: H.F.S.O.

I almost woke up  my wife going in the basement in a hurry...

I sawed one of  the pipe of the third set to improve the set  by being near of the area of the golden ratio...

A good thing, listening the same files in a few second all was better, at the same times the sound was  more focussed in all frequencies but without loss this time in the "meat" around the " bone" of  each tone ....

Greater pipe: 23 inches 1/2, the second one near 14 inches, the last pipe around nine inches.... BINGO!.....

Third set completed and i go back to the music....

More to come....

NEW ADDITION to my room controls devices:
                                                                         A second ionizer,



From China, low cost and very efficient... Low noise level and ozone emission tough this time, it is not the same design of the french silent, ozone-free Moskitoefree....But the french company is assailled by asking consumers and cannot deliver anymore in America...(Moskitoefree repell moskitoes,pull down viruses to the ground, and ionized the room for 100 bucks !) i was sad but,

BUT the  sound result are the same, and i put it where in my room the very low noise level is inaudible...the  silent Moskitoesfree is over my desk between the speakers....


The effect of the Chinese ionizer are the same than the Moskitoefree at least and perhaps more powerful because bigger battery, and 20% of his cost....Peanuts.... Design is aluminum and sturdy....



Audible effects are perfectly audible in high frequencies perception and on imaging.... No doudts at all.... It is not placebo.... I listened to test it some very difficult files ....

This addition of ionizer are amazing.... I cannot live without them now.....

In my 2 postions of listening the effect is the same in imaging, high frequencies and an impression of an increase in soudstage....For 20 bucks....

Dont trust the market, dont trust the reviewers, dont trust anyone save you ears and creativity...

Dont upgrade, embed it.....

UPDATE to my new room controls devices:
A second ionizer,


I confirm the extraordinary effects on the better "timbre" perception by a liberation of the higher frequencies from their captivities in my room...

The Schumann generators grid did that to some degree, the French ionizer too, but this Chinese one is more powerful at least on par with them...

The files of lute i listen to now reach another level in the harmonic perception, and the silkier violin in Vivaldi resemble more of an addiction than ever....


In a word: an icing of the cake yes, but way more, because we never know what we are lacking in audio experience before experiencing it first.....

UPDATE to my new room controls devices:
A second ionizer, a low cost chinese one,

I said that the chinese ionizer affect first the higher frequencies, and it is right...

But there is more than that, the bass notes of a pianio for example are way more clean and more detailed also...It is like upgrading my Sansui to a new amplifier.... 😛 Very strong audible effects across the frequencies with a more 3-D holographic imaging at the 2 positions, nearfield and more regular one....

This is amazing for 20 bucks..... I order another one, hoping to assign the very good and more costlier Moskitofree for the most important job for which it was first designed ,putting down the viruses on the ground.... The model i have is the one with a necklace useful when we take a bus, when we go to the grocery, or when we wait in a closed location....


I listened to my system which for his low price is one of the best there is no doubt.....🤑

500 bucks is all is needed to smile listening music, and laugh at the idea of ANY upgrade at any cost...

I dreamed to buy a Berning ZOTL amplifier, and the Harbeth speakers, but at 10,000 bucks it will probably stay a dream.... But no frustration anymore about that for a longtime now, only the proudness associated with my ratio : low price system/ high quality sound.... 😊😉😎
