In the original product proposal to Fostex, yes...removable cables were requested. Though It was in the original requirements, it didn't make it into the original version of the TH-X00 as Fostex is very methodical and careful. They spent years working on their removable cable system to make it their version of perfect. They could have done it in a few weeks, but it wouldn't have been a true Fostex solution.
Removable cables for the TH-X00 line is one of those features that the community never stopped pushing for and we never stopped requesting. This feature is so important to the community and to the headphones, that we renamed them: TR-X00 (The “R” is for removable.) If you haven’t been following the journey of the first Mahogany version of the headphone into the Purpleheart and Ebony wood variants, we offer three different wood types for different aesthetics and slight sound signature variation. However, since launch- the most requested (demanded!) change has been the ability to remove or swap cables. Why?  I’m so glad you asked! If you develop any issues with the cables over time, you can replace them. If you need a specialized cable to connect to gear or wish to have a personalized cable, you have options. (In the discussion comments which follow, please let us know if you modified your TH-X00 to accept removable cables and how you are using them now…Matt Takaichi is paying attention and sourcing cables for the community.  We’ve transferred the comments from the original headphone drop pages so that none of your contributions have been lost.) Thank you for your support of this headphone, it has been a true success due to community feedback and participation.
FYI, this latest change is the only one that we have planned for the series, we don’t have any other surprises on the horizon at the moment.  (I know somebody is going to ask me!) For now, the time has come and the TR-X00 is available for ordering on June 1st!

I agree! I want to build balanced cables for these.
Th610 has a completely different sound signature compared to the TR-X00.
Will these work well with a magni 3 + modi?
To be honest I've tried many dacs and amps on them and I'm convinced they don't really need an amp. They sound best straight off my phone. With other dacs and amps they just sound "different" but not really "better". Though if you already have magni 3 and modi then it doesn't hurt to try them but I'd still recommend just run them off the phone first lol.
This must sound very stupid but what is the difference in sound of the massdrop fostex TR-X00 vs the fostex th-900
Not stupid at all. The TH900 has a more powerful driver (1.5 T vs. 1 T magnetic flux density), it is the flagship whereas the TR are the same design as the Foster OEM variants (E-Mu etc). Basically the TR is a modified TH-610. Soundwise, the different TR wood variants have slightly different character (Ebony neutral, Purpleheart v shaped, Mahogony splits the difference). I only have direct experience with the TR Ebony for comparison with my TH900. The TH900 has a more pronounced V response, it has noticeably more bass, but it is also brighter and has a dip ~500 Hz. The Biodynamic drivers are good enough that they all respond well to EQing, but the extra horsepower in the 900 makes it a particularly good candidate, but also one that can requires some tonal correction for neutral sound.
I received my package. Was looking forward to it all week. Listening now.... Underwhelmed? Posting this in the Discussions as this is not a review. Seeking tips/advice. This is my first purchase of quality headphones, ever. You can call it splurging. But I think I have an above average ear when it comes to observing sound, picking out details, etc. Used to produce music as a hobby for 8 yrs or so (whether I was good at it or not is a diff discussion). With that out of the way, I expected more as a lot have raved about the bass. Yet here I am halfway jamming out, trying to love these headphones but my ears are saying otherwise and I'm becoming less convinced that I made the right purchase. Is it the headphones, is it this particular finished good (I actually work in manufacturing so fully aware of the imperfect world of it), are my ears not as good as I thought they were, do I have to break these in further (listening for 1 hour)... I don't own any DACs. I'm powering this through my LG V20 which has a DAC but I presume it's weak. If I were to buy a decent DAC and power the headphones through that, would it make a significant improvement? Fuck... Thanks in advance.
try an amp, I suggest a magni 3
From my personal experience this headphone sound the best straight off phone. I've tried it on SDAC/O2 also iFi Nano Black Label and I still like it better from the phone (Google Pixel 1). I'm convinced these headphones don't really need amp (own Mahogany, Ebony, E-Mu Teak and Denon D2000). That being said, they do benefit from burn in. My Ebony's bass sound muddy and bloated when I first got them, as I burn in the sound gets cleaner and cleaner. Some recommend 100 hours but I think for me after the first 2-3 days it kind of doesn't change too much after. Tonality wise I like Mahogany the best (very warm and lush) but it also has the least sound stage out of all the Fostex variants. I would try a low power source and also if you've only played it for 1 hour I'd give it more time to burn in. Give it more time and report back to us after 3 days. :)
Just ordered ZMF lambskin earpads and a lawton tuneup kit. These cant come soon enough.
would've liked to see these on sale
how do these compare to the audeze mobius headphones?
Sounds similar to the warm preset, fostex way more comfortable.
I received mine last week and I am very happy with how these headphones sound. Build quality seems so-so judging from the choice of materials and design solutions, all I can hope for is to enjoy them as much as possible.

looking for some fun, bass emphasised headphones. Already have Senns for detail and soundstage. Are these that, or should i go for Denon's?
Which senns you have for soundstage? The 800's?
I'm thinking about pulling the trigger on these. I do like bass and a big fan of hip-hop. Maybe tonight, but if you guys' know any other alternative, please share. I hear these are the best cans under $500 for Hip-Hop and EDMD/Dance.

I ended up buying them and they became my favorite cans for hip-hop and EDM. The bass is so tight and deep. I have over half a dozen cans, and they are in my top two. They have a unique sound to them, I can't explain it. Although people claim the bass is exaggerated, I love them for it.
lol nice glad you enjoy them, may I ask what's your other favourite can? (since you mentioned top two lol)
another overpriced , such garbage, much disappoint in this site site money grab
Hey guys, any suggestions for an aftermarket cable I can buy that is shorter and will plug directly into a FiiO A5 output?
I wish the logo wasn't so big, and placed in the most elegant spot of the headphones. If they move the logo to the headband, they would instantly appear sexier.
U could always get a E-Mu Teak / Rosewood / Ebony
So recently the hanger on my pair of TH-X00 broke in the all too familiar way. Luckily my warranty was still active and Massdrop replaced them with a brand new shiny pair of TR-X00.
I love the sound, and without a doubt want to keep them....
However in doing some research I have found that the part in question that broke has been known for years to be a design flaw (single stress point that simply will not hold up to years of use), and that at some point it will likely break again and will likely NOT be under warranty and cost over $60 just to replace the hanger, more if I have to replace the screw as well. Which seems excessive considering the frequency of the failure of this piece.
Before even taking the headphones out of the box I have purchased a Slappa Ballistic case for them, to prolong the inevitable. Always treating them like they are made of lab glass should make them last a few years longer.
But I am wondering if anyone has simply replaced the headband? Does anyone know an option for this?
i've been looking into this. The Audeze Headband might work, but haven't found any information about this.
Between the Ebony, Purpleheart and Mahogany which would be the best buy??
best buy would be the mahogany for the 50 - 100$ savings, but best sound is subjective and depends on what your goal is with these headphones.
I feel like I’m going crazy. These were sounding like junk playing out of my LCX using the stock chord ending in a 1/4 jack (yes I know the LCX is a balanced amp, other cans sound fine using the SE output). By Junk I mean none of the bass these are supposed to have. I definitely tend to prefer dark or V shaped gear. When I realized how low the impedance is on these cans I started searching for a replacement cord with a 3.5mm end so I can run it straight from my phone or my FiiO X1. Eventually I got tired of searching and just used the stock 6XX chord which fit...
And wow these sound much, much better running just off my X1 or my iPhone 6! By better I mean the entire frequency range sounds better especially the bass end and the detail is greatly improved (my ears are still getting used to hearing this much detail since I’m new to audiophile land). Then just for good measure I tried to use the same 6XX chord (with an adapter) to run the Fostex cans through the LCX (I’ve tried using the X1 and my computer USB as source) and I swear the sound is better to me when I skip the LCX.
I’ve thought that maybe the EQ on my X1 is better than my PC but even listening using my iPhone 6 as a source with no EQ has better sound quality than running PC to LCX and using the EQ in foobar.
I’m fairly confused.

Lol I think that's why I bought and sold like 4-5 dac/amps already before I conclude it's not necessary to use one. Though I've also heard users on massdrop mentioned it sounded really good with grace m9xx or the aune x7s, but at this point I don't think I have the courage to keep trying lol (those are like $500+). After sdac/o2 (luckily only $150) I'm like nope I still like it off the phone better I think it's time to draw the line. Hahah though I did't mind the quarter inch jack it feels nice though you do need an adapter lol.
Misconceptions about this hobby can be very expensive, which is why it’s so dangerous for newbies. For people on tight budgets one bad purchase can seriously derail someone’s enjoyment. Even when you try to be careful, it’s confusing and it doesn’t help when companies lean into that. Oh well!
Can anyone help me. Am looking for a replacement for the 1/4 to 1/8 inch adapter, but i don't know if they are all the same or if only a specific one will work.
They should all be the same, but to avoid breaking your headphone jack, something with a bit of cord will distribute the weight a bit more evenly. Something along the line of this will be better:
after a few days of use i start to feel that all vocals kinda shifts to right, like the soundstage moves a little bit, does anyone else have the same issue?
Has anything with the Gimbal been addessed? Is it still plastic? I ended up returning my th-x00 under warranty b/c it broke. I recently picked up the HE-4XX to try out as replacement a "good enough"...and .. I really miss my TH-X00. I'm looking at ordering these, but the Gimbal being so fragile just really bugs me.
My Periapt Cable just came in. I had emailed them and special ordered it. Cost me around $110 but it is so worth it. As you can see in the pictures, I got the 5ft in Red. The headphones you see in the picture are the TR-X00 Ebony. I used Plasti-Dip and painted them Red. Now I'll have to get a new Plasti-Dip red so they can match the cable. lol. Contact them at and tell them what headphones you have and they will work with you. They haven't posted this new connection yet on their website cause they are still ordering more connections. I was the first one that brought it to their attention about the connections on ebay, so I got first dibs. lol.


How about Schiit Lyr 2 with these headphones? Any comment or feedback. Thanks
trying to decide between these and a pair of closed back lcd 2 classic, any audiophiles out there willing to provide advice?
Has anyone been able to get/purchase a replacement set of gimbals for these, from Massdrop or otherwise?
Hey guys, so if you want to take a shot at creating your own cables, you will need the connectors. Here is a guy on ebay that is selling them. Good luck and let me know how it goes and take pictures. These are actually the ones that will be using. He is getting them from them. Here is the link.
Custom cables for Fostex TR-X00 (Finally) Hello everyone. This is for the people who have purchased the Fostex TR-X00 headphones. As you know, they come with that very heavy and long (10ft) cable. To this date, there has never really been anyone making aftermarket cables for them. I just facilitated a process between and a company in China. does custom cables and this China company will be providing them with the connectors that are compatible with our headphones. And the best part, they fit. lol. Most people were using the Sennheiser cables but they are not a great fit and look. Once gets the connectors, they will display them on their website. They said it can take up to 3 or 4 weeks. So keep an eye out for them soon.
After a google search (because still have nothing on their website) I found via ebay. They sell cables with the TH900 plug (which should be the same on this one) I havent bought cables yet but surely will an can report when they arrived!
My cables arrived yesterday and they work flawlessly with the TR-X00!
Hello TR-X00 proud owners. I have some pretty good and cool news... I have contacted and advised them of an ebay seller that is now offering connectors that are compatible with our headphones. will be contacting him soon, to try and buy in bulk. If he is able to get them in bulk, they said they will start providing a cable option for us. The moment he has them available, I will be posting back in here with the link. So basically right now he is selling the Sennheiser cables for $56. So our cable shouldn't be any more than that. Again, I will get back to you all soon.
Hi can you link to the eBay seller? I’m trying to attach them to an audeze cypher cable for the built in dac / amp and the connectors I got work but only barely and are prone to fall out.
Anyone try the Lawton demon headphone mod? Does it really help? Is it easy enough to do yourself or should you send it in?
Mods really do work on these headphones. The biggest improvement is by changing out the earpads. The hardest part about doing it yourself is to be VERY careful when you unscrew the screws from the cups. These screws are so small that they are very easy to strip with your screwdriver. So be patient and slow. Also, just make sure you don't pull on the drivers cause the wires are so thin. But modding them is very easy. There are some youtube videos on doing it and plenty of websites showing you how with detailed pictures of every step they took. I personally think it is worth it because you have a pride knowing you did it yourself and hearing the results of it. Makes you appreciate your headphones a little more.
So the screw assembly holding the phone to the headband on my pair stripped off, what would be the best way to get a replacement bolt/screw??
There were a few old subreddits in the past. See if you can locate the TH-610 (shaft) part #1420562475 or manually search it via Fostex's parts distributor ( I only found the TH-900. Maybe even contact them?
There are 2 websites I know of that deal with parts for Fostex. They are, and
Email both of them and ask. When I asked if they had the screws that hold the cups in place, they said yes. So hope they have what you need.
For sale thx00 ph serial number 00993 $260 sanded the cups down cause I didn’t know I’d sell them doesn’t effect sound

That’s what I thought. Thanks ;)
Did you sell them? If not how much are you asking?
I own the original TH-X00 version, I've been using them at work and I've been just using it straight off my Google Pixel phone. Was hoping to have a better sound through new dac/amp, but I don't know if I'm crazy or if I'm just not looking at the right dac/amp. I haven't been able to find something that's a direct upgrade.
Let me elaborate, so I've tried almost all the budget dac/amps but I've been just getting "different" sound more or less. Like I'll gain something but also loses something at the same time. Budget dac/amp I've tried include FiiO E10K, Schiit Fulla 1, NuForce UDAC3, SMSL M3, and recently I've acquired iFi Nano iDSD Black Label.
FiiO E10K - Everything's good overall but loses some bass with bass boost off, with bass boost on it's too boomy. Schiit Fulla 1 - Slightly more V shaped, increase treble and bass but vocal gets further away. NuForce UDAC3 - Similar to Schiit Fulla 1 where it's a little bit V shaped, boosts treble and bass but vocal gets a bit further away. SMSL M3 - This improves clarity and layering and instrument separation by quite a bit, vocal is forward though loses bass too. However I almost kept it but ultimately I find the vocal and bass sounded a little bit artificial. Like you boost certain frequencies too much then they start to sound "off" I can't fully explain. iFi Nano iDSD Black Label - This is the most neutral one out of all of them, also the priciest one yet (about double the cost of the rest). But because it's the most neutral one so it's a more relaxed sounding signature, the treble isn't too much and vocal is forward but loses bass a little. But clarity and layering and sound stage didn't stood out too much for me. Just overall felt a little bit flat despite the raving good reviews.
So at this point I don't know if it's just that TH-X00 is very easy to drive also fairly sensitive headphone so it doesn't really need a new dac/amp, OR maybe things won't start to sound good until I hit the Aune X1, Grace M9XX tier? At this point I even wonder if O2/ODAC or Schiit Magni3/Modi2 will be able to make any real difference (since iFi Nano iDSD Black Label is suppose to be in the comparable tier, unless it's just bad pairing).
Again to clarify, I'm not saying running off Google Pixel is the best thing ever. It just sounded the most natural and correct amount of treble/vocal/bass and maintain the most amount of micro details, trade off is that sound stage is pretty average and instrument separation is decent but not the best. All the above mentioned dac/amps seems to enhance certain frequencies but all the tiny little details seems to get washed out, like all the tiny tiny background sounds. Though I'm not saying any of the above dac/amp are bad, they all sounded good actually, but you get different trade offs, so I feel like if I'm paying extra money to hook up another device I was hoping everything to be better. So at this point I almost feel like it's better off I just run it straight off the phone at work (less things to carry too). As I've mentioned that since I'm running it at work, I don't know if it's worth it to leave an Aune X1 or Grace M9XX at my desk at work. Granted it's a fairly safe work place but it's still open concept so anyone can really just swipe anything off my desk technically.
For now I'm going with the "if it ain't broken then don't fix it" approach and might just leave it for now. What do you guys think? Lol sorry for the super long message, but I start to wonder if it's just me.

Apparently it doesn't have the loud to louder issue, maybe it's due to the type of volume control they use. Then again, neither does the CTH with its ridiculous gain.
That's quite interesting that your nano doesn't have any volume issues, yet the micro does...
The Arcam can actually be found for around $240 shipped from the UK. The site is Analogue Seduction.
It's not even the lack of bass that's bothering me, it's the brain hurting channel imbalance at low volume. I'd be shocked if there's a better amp for detail and clarity, this thing is pretty unreal in that aspect.
Honestly man I got my eye on this amazing portable option just like the IFI Nano Black Label but it's actually putting out more power and from what I heard from this company they have amazing Clarity really trying to link up with them to get this device it just came off of drop a couple days ago but if it ever comes back up again check out the centrance DAC portable it actually has stronger power than the IFI Nano Black Label and if you get the dacportable it does have bass options as well as treble option. The standard centrance HD DAC doesn't so make sure you get the dacportable
