    MacBook Pro->FiiO E7->Fostex T50RP


    Much thanks to Fostex for the review pair.





    No frills here. The T50RP come packaged in a cardboard box in-which the style seems a bit dated. There's nothing to catch the eye really. The color scheme I'm not a fan of, the red background displaying the black T50RP just doesn't appeal to me. T50RP is in big white letters on the front and below that is a quick blurb about the RP (regulated phase) technology which is patented by Fostex. I'll get more into that later though. On either side of the box it simply says "Fostex Professional Headphones." On the back some product information is given. Inside the T50RP are wrapped in plastic with a piece of paper which has some product information.


    As I said these are no frills. This doesn't bother me though as what really matters is the sound primarily. I do take points away from Fostex though for not including a Stereo to 1/8'' adaptor.


    Design and Build Quality



    Right away these things impressed me for build quality. They made my Superlux HD668b look like plastic toys and they feel more solid than my Audio Technica Ad900. I am very impressed. The cups are made of durable feeling plastic, the pads are soft pleather which are easily removed. The pads are much better quality than the 668b, not only are they more comfortable, but they look better built and stitched. Connected to the cups are bronze colored metal guides that allow the headphones to be adjusted up and down. Connecting both cups together is flat metal with a rubber Fostex imprinted headband around it. On the left cup there is a high quality looking and feeling locking removable 3.5''mm plug. The cable feels solid, not stiff at all and terminates to a thick professional feeling 1/4'' stereo plug.


    These definitely feel solidly built in every way. They have a nice heft to them that adds to the durable feeling. No creaks anywhere.


    When worn they feel nice on the ears. I found the 668b to clamp far too much, and the Ad900 to feel a bit loose. The T50RP feel perfect clamp wise and the pads are soft to keep comfy. The headband is my gripe though. These are heavy headphones and the rubber doesn't do a great job keeping the top of my head from feeling the metal bar it's surrounding. This causes discomfort on the top of my head for long listening sessions unfortunately. This can be easily modded though, which many users have been doing with much success.


    Overall these feel professional. The look, build quality and features are fantastic. The comfort is the only thing I can gripe about, thankfully it's an easy fix.


    Sound Quality


    These have been left burning in for at least 50 hours, more likely closer to 100 hours with music I personally listen to playing through them while at work and sleeping to give maximum amount of burn-in time.


    There's been a lot of hype about orthodynamic drivers lately, I'm personally not knowledgable enough on the subject to know what makes these different than dynamic drivers unfortunately, but these do present music differently than even the 668b, despite them both being studio monitors. Before I go further into the sound though I did mention Fostex's RP (regulated phase) technology, I'm also not highly knowledgable on what this means, but on the Fostex website they have this to say,






    I'm still not sure exactly what it is, but I will say these have the clearest background I've ever heard. I read in another review on these about the "black background" and wasn't really sure what the reviewer meant by that until I had put these on. There is basically no grain, the background simply doesn't exist, all your hearing is the music. I love that. It allows me to hear everything with the maximum clarity these drivers are able to provide, and I must say it makes a difference.


    Now onto the sound. Overall the sound won't appeal to everyone, these are after all studio monitors. That doesn't mean these aren't fun to listen to, but they certainly won't appeal to all. I do find myself reaching for these very often though despite owning my Ad900, while these have made my 668b obsolete. The sound is natural, fast, balanced, and spacious. There's not a huge soundstage, but the headphones have good instrument separation. As for speed, this is one of the key reasons many Ortho fans like their headphones, for the speed in which the drivers are able to present music in. I must say, I'm impressed. From fast paced drum and bass, to alternative rock, to metal, these things have kept up in every department. From 140bpm+ double bass in metal to guitar shredding, to fast triplets on the hi-hat I never feel behind.


    Since these are studio monitors, the goal is to, ideally, have a flat sound. I must say that these do a good job being balanced, though I feel that the mids are slightly above the rest. The highs do sound slightly rolled off, though I feel they're accurately presented. The lows are good, they have good impact and the extension is decent. I don't particularly feel the sub-bass, but I can hear it. The mid bass though has nice impact. The sound signature really works with any genre, but it doesn't stand out with any genre either. It's an inoffensive sound, but it doesn't overly impress either to my ears. Let's try it with some songs though!


    Rubblebucket - Came Out Of A Lady


    I chose this song because it absolutely gives any headphone a work out. From the funky bass line to the wonderful horn section, intimate vocals and huge energy, it makes a great song to test overall. First there's a lot going on here, no less than 4 different horns, a Roland Juno 60 synth, percussion, drums, bass, guitar and vocals. Never once did this song feel congested, I was able to pick out every instrument with clarity. The vocals are wonderfully intimate sounding, I've seen Rubblebucket live no less than 3 times and it sounds just as good through these headphones. The horns come through with excellent authority and clarity. The percussion and rhythm guitar are easily discerned despite being a little lower in the mix than the horns, I'm easily able to figure out what's being played and play it along with them. The synth has a nice warm fuzzy analog sound the Roland Juno is known for. The drums have a nice sound as well, the kick drum sounds wonderfully fantastic.


    Overall every instrument is very accurately represented. The song feels and sounds energetic and honestly it's hard to write this as I want to shake my rump along with the kicking melodies. For a song with a lot going on, which is rather fast paced, these headphones handle it with ease. Compared to my Ad900 the T50RP feels less energetic, but mores accurately represents the sound as the Ad900 lack some bass and are a bit brighter, which causes a focus more on the horns. Both headphones play these back fantastic though.


    Amon Tobin - The Lighthouse


    I chose this song because of the creepy atmosphere and chaotic sound it has. Those who've played Splinter Cell Chaos Theory have heard this soundtrack. The scratchy bassline is haunting. The various sound effects in the background and foreground are causing shivers. Everything sounds wonderful and clear so far, much better than I thought on my Ad900, which aren't particularly known for being the most clear headphone. The jagged cut up beats are hectic and the T50RP keeps up with ease while allowing the other sounds to be heard, rather than drowning them out like the Ad900 slightly do. Both headphones are equally as fast though, but it comes down to a more accurate sound in the T50RP vs a more energetic sound of the Ad900 again.


    James Blake - Limit To Your Love


    If you've read my past reviews you know I love this song to test for bass response because of the deep, fast, bass. James Blake's soulful vocals sound beautiful, the piano has a nice acoustic sound to it, both linger beautifully. When the bass comes in, the vocals and minimal drum line are actually slightly higher in the mix than the bass. It feels like the vocals and bass melody are sitting on top of the bass line actually. As if I were looking at an aquarium and the bass line were the hectic water and the vocals and bass are sitting on top of it. Now this is how I've always perceived this, but there seems to be clear separation here as if the bass wasn't strong enough to bleed into the vocals. 


    On my Ad900 imagine the same perception, but the bass line splashing up into the vocals and drums getting them wet, slightly drowning them out. Yes, weird right? The Ad900 is actually more bass heavy than these for this track. The bass on both of these headphones is fast, the T50RP extends well and keeps up with the over 200BPM fluctuations in the bass, as fast as the Ad900, but the T50RP just doesn't have the authority unfortunately for me to feel it. The mid bass of the kick drum has more authority than on my Ad900 though. The Ad900 though actually rattle my ears on this, believe it or not.


    Though the T50RP portrays this song beautifully I feel that the bass is supposed to leak more into the vocals and absolutely rattle everything for symbolism purposes. For this song I actually prefer the Ad900, and for bass response at that.


    Feist - The Water


    I chose this as a sibilance test and to see how intimate the vocals would sound. Good news, no sibilance at all and holy cow, Feist's voice is giving me shivers. They sound absolutely beautifully smooth, as if I were in a small acoustically tuned room and Feist were singing in 20 feet in front of me. The stand up bass and piano sound beautifully haunting, but Feist's voice steals the show, especially as she belts out her notes. The Ad900 present Fest's voice a bit too shrill for me, so the T50RP wins here.


    Radiohead - Jigsaw Falling Into Place


    I chose this for some alternative rock. Great energy, great balance, the vocals sound intimate and smooth, the instruments have great separation and balance. I prefer my Ad900 because of the more energetic sound, the guitars sound more lively, but I'm definitely digging the T50RP on this song. 


    Bob Marley & The Wailers - Is This Love


    Bob Marley had some amazing production value and the version I have is the Barry Diament re-master from 1990, arguably the best version of this and boy does it sound good. There's a decent amount of instruments and vocals in this, and everything sound beautifully mixed. Bass is hugely important for Reggae and unfortunately it sounds a bit flat here, the Ad900 had more authority actually. Overall though this song sounds great, very clear, I feel as if I'm in the studio with them. 





    For the price these headphones are absolutely wonderful, especially if you consider modding them in-which there's a huge community for it. These cans stock have a fantastic accurate sound to them and I feel they should be in everyone's collection as a pair of flat headphones. My biggest complaint with these is the lack of authority in the sub-bass, I just couldn't feel it, but thankfully you can mod these to fix that if you're handy. These are quick headphones able to keep up with any music, seriously, try it. The "black background" is something I never would have understood until I heard these, but boy it makes my Ad900 sound grainy.


    Compared to the 668b, well there's no real comparison. Spend the extra money to buy the Fostex T50RP. You're getting better build quality, a bigger community and a slightly more detailed and clear sound. Compared to the Ad900 it's tough. Stock the T50RP just don't have the energy compared to the Ad900 and surprisingly the Ad900 has more sub-bass. Both are fast though. I'm sure I'll find myself reaching for both for different occasions though.


    Pick these up if you have the money and can find them, I don't think you'll be disappointed. One drawback though is that I do recommend an amp for it, my E7 can power them just fine though. I only consider this a drawback though because it's my belief that no sub $100 headphone should require an amp. Great offering Fostex, what an excellent intro to orthodynamics!

    "Buy them and be nice"
    Pros - Absolutely great Mids, Great Detail, Fun to Mod
    Cons - Dull at first, takes a week to learn to love
    I'll be posting a thread reveiw for these later, but here's the short:
    Amazing Mids - beats out $500 headphones
    Great Highs - Close to Grado, about Sr80i
    Good design to play with
    Bad design - can be fixed with mods. Cups and headband would be a dream.
    Bad cup design - play with it for a while and the sound improves
    1/4inch without adapter. Not much of a problem, but at this price I expect a 3.5mm jack with an adapter
    Get these headphones if you love Acoustics, Classical, Some rock, Metal, older music and you like to mod.
    I've already stuffed the cups with blutack and made new, larger earpads. Both have solidified the sound and made them more comfy. Personally, I'm afraid these monsters might become too good one of these days and beat out my other headphones.

    "Go ahead, turn them up a little more."
    Pros - neutrality, chameleon, smooth midrange, detail and speed, crazy good deal.
    Cons - Needs solid amping, can sound a bit flat, takes some getting used to
    The orthodynamic club at Head-fi probably feels a little outspoken at times. They have a less common headphone technology that they believe very strongly is fundamentally superior to the traditional dynamic drivers that we see so often. The dauntingly enormous orthodynamic roundup thread is a testament to the dedication and passion of this Head-fi subculture. To make matters worse, there are very few companies still producing orthos. There are some hugely expensive offerings, but only one brand making affordable offerings. That company is Fostex, though many consider the new flagship T50RP to be inferior to some of the vintage orthos from the '70s.
    I am not an expert on orthos by any stretch of the imagination, but I was intrigued by the discussions in that thread. The Fostex T50RP are not really that cheap, so I decided to give them a shot.
    I'm glad I did.
    Some of the rumours about the T50RP are true. They don't have strong bass, and they are very neutral and balanced. Anyone who is really into the Grado sound or any other hi-fi sound signature can just stop reading now. For those who like a more neutral presentation, however, these really do offer something special for a bargain price. I've been putting mine through their paces for a few weeks now, and I'm driving them from my Yamaha Home Theatre receiver, and custom built Texas Instruments DAC/AMP.
    Ask any ortho fan what makes them better than dynamic headphones, and they will talk about the smooth, beautiful midrange and an incredible transient speed. This is the paradoxical mystery of the T50RP, because they manage to be capable of enveloping warmth, but also painstakingly detailed and precise. Jeff Buckley's Lilac Wine is one of my main test tracks for vocals, and I've rarely heard him sound better. The T50RP brings out the tone of his voice beautifully, and places it just where it should be in the soundstage. That midrange does stunning things for guitar and piano as well, where the speed and accuracy create some truly beautiful music.
    Of course, at this price we expect some compromise. In this case, that stunning midrange comes at the cost of some extension at both ends of the sound spectrum. With the new earpads (replaced in the lineup a couple years ago), I wouldn't call these bass light compared to a few of my cans, but they lack the punch and depth I've found in my DT990s and DT150s. Massive Attack's Angel does have a reasonable amount of bass, but it is genuinely balanced and never threatens to overwhelm. It lacks definition, though, and doesn't have the velvety texture of the DT990s.
    The same is true of a rolling off at the high end. Treble is certainly present when it's found in the recording, but cymbals don't have the sharp sizzle that Beyerdynamic cans demonstrate. For people who hate sibilance more than anything else, this is a good thing. It takes away some of the space in recordings, though, and although Buckley's voice sounds spectacular on these cans, the track doesn't have the air around it that it does on some of my other headphones. It's overall fairly forgiving on harsh recordings, though, which is more than I can say for my Beyerdynamic cans. As a side note, the same is not true of low bitrate recordings, which sound terrible on the Fostex headphones.
    On Head-fi, we often talk about headphones that melt into the background. The Fostex T50RP are the best cans for this I have ever owned. If I feed them with bright Queen recordings, that brightness comes through with speed and energy. If I toss some Chemical Brothers at them, they push out a bass sweep that never stops dipping lower. Rock music has punch, Soul is laid back and groovy, jazz recordings are light and airy... these work pretty well for almost anything. The first time I put these on, everything felt strange and a bit different. After some time adjusting, though, everything feels just about right.
    There are times that I'm in the mood for other things, and that prevents the T50RP from being my ultimate headphones. Sometimes, I want more bass than I can get from these things stock. There are other times that I want something a bit more musical and aggressive. Still, if I want to hear what a track really sounds like, the T50RP is the headphone I reach for every time.
    Of course, there's more to a pair of headphones than just the sound. These are also some of the most comfortable headphones I own. Once I found the right adjustment with the headband, I find the fit of these is just about perfect for me. There's a point of contact at the top of my head that holds them in place, and since it's rubber, it never slips out of place. There is very little side pressure, just enough to get a seal over my ears. I can wear these for hours without any discomfort, which makes them even better as professional audio tools.
    With the T50RP, it is important to talk about driving them as well. These are not easy cans to drive. Looking at the specs (50ohm impedance and sensitivity in the high 90s), these shouldn't be especially hard to drive, but they sound terrible without plenty of juice. Portable players are right out, and they don't sound good out of my Hotaudio Bitperfect, either. The good side of this is that they will take an astonishing amount of power if plugged into an amp that can supply it. Another peek at the specs reveals that these are rated to handle up to 3000mW, which is borderline absurd. While you would never actually want to put that kind of current into a pair of headphones, it means that these drivers will not distort, even when pushed past what any headphone should be asked to dish out. Of course, that doesn't mean I recommend playing these at 130dB, but apparently they can do it if your ears can.
    I can see how many people have been unimpressed with these headphones during an initial audition. They didn't sound right to my ears, and I find I still have a five minute adjustment period every time I put them on. Once my ears adjust, though, I really enjoy these headphones with almost any music. That, alone, makes them well worth the asking price. If you haven't yet dabbled in the fringe Head-fi experience of orthodynamics, it just might be time you did.
