The Fostex TH-900 was the first high-end headphone from Fostex and it remains the best in our opinion. It's truly a favorite around here and a Best Seller every month at Moon Audio.

They feature a newly designed driver unit with a 1.5 tesla magnetic circuit and bio-dynamic 50mm diaphragm, traditional Japanese lacquered "Urushi" finished craftsmanship housing and a selected 7N OFC cable come standard.

hi-fi+ Review of the Fostex TH900 By: Alan Sircom 


* Required Fields



It is a very linear headphone from the top to the bottom of the frequency spectrum. It does not have recessed midrange or an overpowering bottom end. It is a true reference headphone and a perfect fit for mastering engineers that need a true representation of the music. It is not overly analytical but truly transparent.

For this reason, Drew recommends the Silver Dragon V3 headphone cable as the perfect signature match to take the TH-900 to another level of resolution. It provides just the right snap to the bottom end to control and speed up the bass signature for a perfectly accurate, bottom end. It also adds more depth to the presentation, another layer of clarity, plus, more air to the vocalist's breath and picking of the stringed instrument(s).

The Fostex TH-900 and the Silver Dragon V3 are such a wonderful combination with such synergy and they truly take music appreciation and headphone enjoyment to another level of "ear opening experience", Drew Baird, P.E., President/CEO of Moon Audio.  We think you'll agree....

Best Pair of High End HeadphonesReview by Ivan Ong
Bought a pair of these from Moon Audio and got them recabled with Silver Dragon V3s. A couple of years back, I sent my older Ultrasone Ed 8s in for the same recabling job and Moon Audio made a great pair of cans sound even better, so I know what I am doing.

Spacious soundstage with great depth, neutral, great clarity, especially on the mids and highs, but no slouch on the bass. I have been listening to early twentieth-century composers, ambient, metal and general rock and these cans perform beautifully.

Lookwise, these are perhaps the best looking cans I've ever seen - the red lacquered cups really make them stand out. The headband is comfortable with adequate padding and the ear pads are comfortable. Overall design is ergonomic and lightweight enough for me to wear them hours on end.

Highly recommended. Get Moon Audio to recable them for that extra oompf! (Posted on 4/9/2016)
breat taking ...AND HOW!!!!!!!!!!!Review by David in Texas
I was initially very hesitant to buy these Fostex TH900 headphones, because of some reviews I read on the other sites, by users and analysts. They stated the "mids were recessed". But I said what heck. I purchased the Fostex TH900 with the Silver Dragon V3 cables.

I unboxed it and when I first heard them out-of-the-box, the mids did indeed sound recessed, but I did not panic. I simply took off the phones, and let them burn in for only 12 hours, then tried another listening session, and took care of that it's only weakness.

Fostex Th900 are now the best you can buy (price not withstanding). I've had Grado PS500, Senn HD800, even the "so called best in the world" Audeze LCD-3 (w/fazor). The TH900's make them all sound pale in comparison especially the LCD-3's.

Perhaps the only headphones that can touch the TH900's are the Stax 009's. But I have not tried those, so in closing I highly endorse the Fostex TH900's!! (Posted on 2/8/2016)
Life is complete now :-)Review by Rufatik
I'm new to high end audio but I have owned AKG K812 headphones for a year. One month ago I decided to attend CanJam 2015 and Drew offered me to try the Fostex TH900 headphones.

I fell in love with them and pulled the trigger. I'm not sorry, these TH900 with silver dragon cables are giving me chills. Life is good. (Posted on 4/22/2015)
Best SILENCE You Will Ever HearReview by Curagami
We were somewhere in Tennessee. I'd been riding a bicycle for more than a week. Over 500 miles lay behind us and almost 3,000 lay ahead. But we weren't thinking about "ahead" or "behind" on this chilly July morning.

We started riding before there was sun. Now flat, grey trees were showing their first signs of brilliant color. A cloud seemed trapped on the ground. "Ground fog," my teammate said snapping a picture.

The world wasn't awake yet. God's palette would wake with the sun, but in that moment the world was foggy, flat and there was a furious silence. A silence to pervasive and filling it made a sound or left the impression of one.

That morning standing in a field in Tennessee felt like Fostex TH900 with Silver Dragons SOUND. The clear ringing bell somewhere far up in the Himalayan mountains is what it sounds like to listen to music with my Dragon equipped Fostex's.

They feel great too. Substantial enough to click the band to cup my ears, but not fatiguing or hot (hate that feeling of weight and heat on my ears). The sound is so light, I have Chick Corea's Light as a Feather on now, these cans could have afforded more weight. That they don't need it is testimony to Fostex's engineering, Drew and Moon Audio's magical Dragon audio cables.

Wearing these magical cans at the James Cancer Center recently I was oblivious. Bring it on whatever "it" is because I'm in a field in Tennessee somewhere and God hasn't painted our day nor the Monk's woke us up with their clear ringing bell just yet. Time suspends and you feel the music as much as hear it. (Posted on 4/21/2015)
Finally, a headphone that exceeds all my expectationsReview by Nicholas K.
I cannot explain how difficult it is to research the headphone that is right for you because every headphone has a different sound signature, people have different preferences, and perceived sound is subjective. It’s been an enlightening journey auditioning a wide array of headphones each with their own strengths and weaknesses, but at the end of each trial my expectations were never fully satisfied across the board. I wanted a linear headphone that had full bass, uncolored mids, and sparkly treble and I had almost given up on my search for audio perfection because headphones that excel in one variable typically lack in another. Enter the TH900.

I did not have the opportunity to demo the Fostex before purchase, but Drew’s top headphone picks video coupled with a plethora of internet research led me back to the TH900 time and time again. I had already tried several other brands TOTL headphones and knew exactly what I wanted and it was time to see if the Fostex would live up to my hyped expectations. I placed my order with the Silver Dragon cables with unbridled excitement and received an e-mail later that day explaining the shipment of TH900s would be delayed for at least a month. Excitement deflated.

Fast forward two months of waiting on the sidelines with uninspiring headphones and IEMs and I get the e-mail that they finally shipped! I took my time to unwrap the box, despite the fact that I already knew every last detail after watching a plethora of online reviews. Everything was as expected. I will add that the Silver Dragons look as if they belonged to the headphone with no evidence of the surgery that inevitably took place to remove the attached stock cables.

I plugged the Fostex into my newly minted Hugo Chord and queued up my favorite reference tracks. Everything was not as expected. There are some things in life where you just know what the experience will feel like because of online reviews, first hand recounts, and personal affairs, but this connection to the music left me speechless. I mean that literally; I can recall holding my breath through specific passages just in awe of the effortless presentation of the music. All this time I thought I was expecting too much out of these TOTL cans to deliver bass, treble, soundstage, transparency, and the TH900 nails it on all fronts.

I didn’t want to sacrifice one aspect of the music for another, but the Fostex doesn’t force me to choose. It’s just the right amount of bass, treble, mids, and soundstage for my preferences, but whole is more than the sum of its parts. This is the experience I’ve been missing and well worth the money at this price point.

Special thanks to Drew for giving me the unbiased feedback that I requested to help me make the best choice for my needs. I could feel the passion that Drew has for music and that was a driving factor in purchasing from Moon Audio. In addition, the Silver Dragon cables are unlike any cable I’ve ever seen and something one needs to hold in hand to truly appreciate. (Posted on 4/6/2015)
Fantastic Choice Made for Me by Drew!Review by Michael - The Old Mad Dog
Living in Denver, I always attend CanJam. This year, I went for the sole purpose of purchasing the Audeze Lcd-XC because I forgot to order them after the 2013 CanJam. I ran into one problem - at the age of 63 the joints in my neck are terribly arthritic and Audeze is just too heavy.

Drew had me try the TH900 because they were lighter. I ordered on the spot. Oh my gawd! My pair with the Silver Dragon and the adaptors for balanced listening or 1/4 inch amps arrived on Friday and they are incredible.

As everyone says, they are incredibly linear, more than enough bass and the soundstage is wide and fantastic. They don't even sound like a closed headphone. One drawback - the treble is a little "hissy". I'm chalking that up to not being broken in and the Schitt Lyr I'm using right now.

Everything I'm listening to sounds fantastic. All hi-rez files including Dusty Springfield, Bob Dylan, Canned Heat, Arianna Grande, Jesse J, Black Sabbath, Blind Faith, Deep Purple, American Authors, Neon Trees - they all sound great.

I just need to find the amp/dac combo that works the best with the TH900. The simple solution will be to e-mail Drew. He's sold me three pair of headphones (all for different purposes) and hasn't steered me wrong yet.

My gosh, closing your eyes and listening to Dusty Springfield through the Fostex is just like being in Memphis next to her. (Posted on 10/30/2014)
Highly Recommended with HUGOReview by Howard
I asked Drew what he would recommend to use with my HUGO. He quickly responded and there was no hesitation in his response. He recommended the Fostex TH900 with his remarkable Silver Dragon.

The HUGO is a remarkable DAC, whether being used in one's main system or as a portable. When matched with the FostexTH900 the sound is sublime. I have heard some claim these cans are recessed in the midrange or somewhat bloated in the bass, but I find no such issues. I have tried the HD800s with the HUGO and while they are obviously excellent headphones, in my opinion, the TH900 is the better match. I have never heard the TH900 with the factory cable so I am not sure if some of the comments regarding "V shaped" frequency curve is a result of the factory cable, BUT, with the Silver Dragon, I find a wonderfully linear and coherent sound with extremely accurate timbre.

My home system includes ARC, MSB Diamond Plus and Nola Concert Grands and while the HUGO is no Diamond Plus, it is close enough to make it the best deal, IMO, on the market. The TH900 plus Silver Dragon V3 headphone cable, the HUGO & my iPhone as a source brings a smile to my face almost equal to my home system. I love the combination. Plus, they are gorgeous.

Silver Dragon V3 SOUND is OUTSTANDING with the Fostex TH900 - adapter cables tooReview by Koth

You and your team at Moon Audio brew pure magic in your Silver Dragons. The adapter cables that you made for my Fostex TH 900 are truly beautifully made and the sound is outstanding. From the extension on both ends, the detail and the instrument separation, the Fostex sounds outstanding now.

A big cheer for all of you at Moon Audio.

Wonderful immersive soundstage Review by Theo
It's all here baby. You couldn't ask for more. These cans have the bass that's deep and controlled. The Mids are are smooth and the treble has a silky sound. When I put these cans on my head I'm good to go for a twelve hour stretch of listening to Jazz, Rock ,country, and female vocalist. I'm happy, very,very, happy. Money well spent. (Posted on 10/13/2013)
Wonderful headphone, cheaper then before. Review by Audio Otaku
I'm in love with these cans. They are a nice combo of accurate, but fun, and look drop dead sexy. I bought these before the price drop and still feel I would pay the price I did. (Posted on 9/26/2013)
PhenomenolReview by Alan
I've owned Em all, Grados, Senns, Audeze, Denon, etc. These are by far the best and most outstanding headphones I've ever heard. The absolute cream of the crop! (Posted on 1/22/2013)
The low frequency reproduction was amazing.Review by Wes
After listening to the TH900 I realized what my Sennheiser HD800 headphones missed on the low freq. end of music.
Wow what a sound. (Posted on 9/26/2012)
breath taking!!!!!Review by xenomorph
