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...

We ever underestimated the negative impact of resonance and negative mechanical vibrations on the gear...Even those like us that are conscious of the fact... I added sorbothane (compressed with tapes because sorb must be compressed to works better) to separate more the 2 cups linked by the headband... After adding band of sorb along the plastic arms that pivot on the cups by 2 points, the results are more 3-d holographically organic imaging...I was amazed already by these cheap Fostex TH 7 , I am more amazed...This low cost Fostex are the best headphone ever relatively to the ratio quality/price...i will not upgrade this... The akg 701 dont have an organic 3-d imaging... Only an incoherent big soundstage, and mids frequencies more artificial than the Fostex… The Akg 340 is better for the mids frequencies, almost king there among most of the headphone, but his good imaging are more artificial than the Fostex, his soundstage smaller on all count...And this AKG is too unconfortable for long use...The Hifiman 400 is no match nor the Stax i owns for naturalness of the timbre musical or voice except the Stax SR5 very good on this count but less amazing in the imaging and soundstage...Fostex TH7, semi-open; the last version is completely closed, improved, but is the fantastic imaging the same? I will buy one for sure this year...


For me except the imperative necessity of the natural voicing of the timbre, the most important feature of an headphone is his capacity to mimic speakers, for that the sound must not be only around the brain, but must seems to come from at least outside the head with an atmospheric distance between instruments (imaging)...Almost all headphones lacks these 2, and those that posess the first quality 9like the AKG 340 or the Stax SR5) lack the second (many headphone like the AKG 701 are a compromise between these 2 qualities but they excel at none)...It is the reason that i try many headphones, and after all these trials conclude that headphones are not from me...I decide then to try at last the cheaper one, with many modifications, and the results is there : they sound better now, on par, but differently than my speakers...I enjoy headphones now very much... Is there better headphone than this Fostex ? Hell yes ! But probably over 500 bucks is my guess, perhaps more, because natural mids frequencies coupled with perfect organic imaging is probably linked to the TOTL line of headphone...Dont forget that new they sell them now 100 bucks at most...
First up...The Moody Blues, A Question of Balance

After he had journeyed,
And his feet were sore,
And he was tired,
He came upon an orange grove
And he rested.And he lay in the cool,
And while he rested, 
He took to himself an orange
And tasted it,
And it was good.
And he felt the earth to his spine,
And he asked,
And he saw the tree above him,
And the stars,
And the veins in the leaf,
And the light,
And the balance.
And he saw magnificent perfection,
Whereon he thought of himself in balance,
And he knew he was.

Wow! Wow! Wow! 😮
