Extra Features
Not content with just providing monster-level amping, Fiio added a crossfeed feature as well as the usual Bass Boost knob. Being used to the multi-step Bass control of the Fiio E17/07K, the one level bass boost on the E12 seems a bit primitive. However, the result you get out of that Bass Boost is great and may be the best Bass Boost so far. The strongest boost happens on the low bass section which you don’t see very often with Bass Boost, while the mid bass boost is more mild. And while BB usually adds some degree of boominess, on the E12 it remains tight and controlled.
The crossfeed provides a good job in filling up the center image while not muddying the sound. This is definitely a better crossfeed circuit than what we see on portable amps 4-5 years ago.
Headphone Pairings
Having proven itself with the Hifiman HE-6, I felt that the E12 should be able to tackle everything else in the market with ease, and indeed it does. One of the best E12 pairing is with the Hifiman HE-400 which I really felt the E12 injects enough low treble energy and overall PRaT to make for an enjoyable toe-tapping experience. Strangely though it powers the Audez’e LCD-2 and Fostex T50RP (and its derivatives like the Mad Dog headphone) just fine, I didn’t feel the synergy to be there.
The E12’s fast and energetic sound signature in theory should blend well with headphones that I consider can use some boost in those departments, namely like the AKG K550 and the Sony Z1000, but the result was just okay. The E12 had too strong of a solid state characteristics and personally I’d like a little bit more fluidity in the sound. It does work nicely with UltimateEars’ UE9000 and Philips’ Fidelio L1.
Volume control was good enough to avoid major imbalance with IEMs at moderate listening volumes. There are bound to be some slight imbalance at very low volume levels as in perhaps 99.9% of all analog potentiometers, so if you’re a low volume IEM listener, beware. Also like any other high-powered amps, you’re bound to get a limited range of steps with the volume control.
I used the E12 with a number of different IEMs. A few models from T-Peos (H100, D201, D202), and also FitEar’s 334ToGo (I know). I really didn’t feel IEMs to be the E12s strength. I would rather a lower power level amplifier with better refinement like JDSLabs’s C421 or RSA’s Shadow at the premium range.
End Words
This is a real fun and punchy amp for the orthodynamic market. The E12 drives the HE-400 just fine on low gain, but I use the +10 gain setting as it delivers better dynamics for the HE-400. I know that the orthodynamic market is booming, and the E12 is the right headphone for those of you looking for a good amp for your ortho headphone. It’s no Burson Conductor, but the Fiio has enough grunt to make good music with the HE-400.
George Lai
Hi Mike. Though I have both the e10 and e11, I’m still very tempted by this one. Two questions: 1. what (replaceable?) battery does it use? 2. Would it pair well with the Senn HD600 and Philips X1 for rock? Thanks
Mike
For the HD600 and X1 I would still prefer the ALO national.
It’s a matter of synergy really. Primarily what I’m looking for is a smooth mids with the HD600 and X1.
George Lai
Thanks Mike. But what would you recommend closer to the e12’s price? The ALO is a lot more expensive.
Trent_D
The cMoy or the C421 would work well with the HD600.
Isaiah Mackler
Personally, I thought the HD600 was much better with the E12 than the C421. Its not the perfect pairing, but for a fraction of the price, I’d pick the E12 w/ the HD600 over the National, too. If the National were to cost $200, I think it would be a tougher choice. Really, wish Mike could review the Soundlab V.3. I thought it was as good as the National and better than the E12 w/ the HD600.
Mike
Thanks Isaiah, will look into the Soundlab V3.
Eu Jin
Hey Mike talking bout the ALO National have you got your hands on the new International? Would hope that you can do a review on it. I’m not sure whether both have the same amp circuits or not.
Mike
As for the battery I haven’t checked but I will try to open it later or tomorrow.
Florian GERARD
Hello
What about hd650 pairing? Thks that a perfect review as i was considering to buy it this month 🙂
Mike
Thanks Florian,
I didn’t enjoy it with the HD650.
Florian GERARD
Thanks
Neill Martin
which amp would you recommend for HD650 In similar price range? Or is it Graham Slee or nothing! 😀
Mike
Portable or desktop?
Chris Allen
Hey Mike, great review!! One question, would you consider the E17 to be a better amplifier than this one since it focuses more on bass, power, and PRaT?
Mike
No, not really. If you’re looking at the E17 you should wait for my E07K review coming up next week which I think is going to seriously eat into the E17’s market.
Chris Allen
Very interesting… I will still tuned as always then. 🙂
Mike
Yes keep in tune 🙂
Carlo Maria Sivo
Try it with AKG K550. What do you think?
Mike
I did write about the pairing with the K550.
Isaiah Mackler
I think you sum it up well when you said it has a classic solid state feel to the E12. Thanks for the review!
Mike
Thanks Isaiah!
Nielven Olis
what do you guys use as a reference headphone/amp when you describe the amp as “Midrange section is full and with a good sparkle. The sound signature is forward”? I am worried this will be a colored amp since I am very much interested in a neutral amp like magni(although it added a bit of treble using Shure 1840 everything else sounded the way it should) but with portablity and power.
Mike
Nielven,
No particular amp that I’m referencing to, just based on my experience with the other amps in the market. It’s definitely not a dark amp or a laid back one.
I am afraid I have no experience with the Magni (Julius did the Magni review) so I can’t really say, but if you’re afraid that this amp would add more treble to your Shure than what you really want, I think you should look into the Matrix Mini Portable though it sells for considerably more than the E12.

how does the E12 compare to the O2?
Mike
Sorry I haven’t done that comparison.
Guest
How’s it with the Q701?
Mike
It should powe the Q701 just fine but I haven’t had the chance to try it personally with the Q701.
Magnus
I record music and have a Focusrite soundcard like this, http://global.focusrite.com/usb-audio-interfaces/scarlett-2i2
Will i benefit anything from getting a small amp for my headphones? I currently use a pair of Sennheiser HD598 but will upgrade soon.
Papoom Vibhatasilpin
Hi Mike. What Do you think about use Fiio E10 line out to E12?
Mike
Sure yes that would be nice!
Jack Knight
hi mike, do you think beyer dt770/250 is a good pair with E12?
Mike
I’m not really an expert in amp pairings for the 770-250 but I think it can be a good amp, yes.
Thomas Bourbon
Hi Mike, have you tried it with an HD25-1 II ? Was it any good ?
Mike
No actually I haven’t tried it with an HD25-1. Sorry I just sold my HD25-1 last month.
John123John
Gasp!!! Replaced by….?
Mike
Well it wasn’t like that. A good friend came by and desperately wanted an HD25-1. I couldn’t say no.
Besides the UE9000 and Fidelio L1 are really nice I haven’t really missed the Sennheiser.
Eyal Sade
E12 vs Magni ?
Mike
No Magni for me. Sorry.
Eyal Sade
So the E12’s better (SQ) ?
Mike
No, I meant that I don’t have any Magni around to listen and compare.
Eyal Sade
ah.. never mind the magni, it works only 115v …(
Asrona
will it work good with my Sennheiser addidas, 25 hd? I need more punchier deep bass. Also i think the sound is flat. Need more soundstage. I bought these headphones, it is very expensive.. so i would try to make the most out of it.. hope you guys can help.
dalethorn
What is your source?
Asrona
macbook pro.. i did a little research myself. it turns out i don’t need an amp. Because of the low impediance i guess. Maybe i need a dac and not the e12.. maybe.
Trent_D
The HD25 is not known for its soundstage. An amp could help with the bass though.
Mike
I think you just described the HD25-1s character. It would be quite hard to change that to be honest.
Asrona
yeah. You are right. I just have to adapt my ears to this “forward” sound. No depth.. not much i can do.
Mike
It works well for Rock, better than a lot of other headphones with bigger soundstage. Sometimes bigger soundstage doesn’t always mean a good thing. The old AKG K501 has a monstrous soundstage but it doesn’t have anywhere close to the energy and PRaT of the HD25-1.
Asrona
Sometimes it is actually good, works well on certian music genres. You are right on that point, i like the clean tight sound of the HD25-1. To be honest, I am pretty grateful for these cans, but i also have in my mind that i want something over the top headphones. I don’t feel that with my HD25-1. or maybe i am just naive..
Mike
No you’re right, the 25-1 does have shortcomings
Neill Martin
Hi Mike, can you recommend good, cheap portable amp I can use in laptop to drive my senheisser 650s. I’ve sold my Graham Slee diamond Solo as needed money for AV amp. What about fiio e7/E9?
Thanks
Trent_D
There will be a guest review coming up that answers this, but to give you a preview, there is no better, cheap amp for the HD650 than the JDSlabs cMoy.
L.
There will be?
Trent_D
You know, I heard their might be.
Mike
Neill
The $60 Cmoy from JDSLabs is extremely good for the 650 for the price.
Ardy Ar
Mike,I’m looking for an amp to go with my Beyer DT880-600 phones.90% usage in a main system with a Cambridge 840A CD player,10% portable with an Ipod.I saw your write up on the new E7/E9 pairing,and this article.Which would suit my needs better?Thanks.
Mike
I would recommend the E7K+E9K over the E12.
Rachit
Out of curiosity, how does this drive the HE-500?
Vaughan Elphick
How does this compare to the FiiO E17? I have it, and found it faulty, when it worked it was brilliant, but after a few weeks things have started to go wrong with it (but its not common as everywhere I have read this has not happened which shows its an isolated issue at least) but I’m wondering if sent back and found faulty and given the option to pay the difference is the Mont Blanc E12 an upgrade or downgrade from the E17?
Thanks in advance 🙂
Mike
Vaughan,
Primarily, the difference is in sound signature. The Mont Blanc is more forward, punchier bass, faster pace amp.
The E17 is less forward, less power, but smoother and more refined sound, better atmosphere.
Vaughan Elphick
Interesting, thanks heaps for that 🙂
Mike
You’re welcome
ExpectationGap
I been paring a FiiO E17 with Ultrasone Pro900’s, and for the most part, was pretty happy with the setup (loved the ability to custom adjust gain, bass, and treble). However, I recently purchased an E12 just to see if it could provide a better level of bass control than the E17. Running the Mont Blanc with gain 16db, bass on, cross-feed off… I’m getting great results. Bass is tighter & features clean decay; it feels like going from a ported to a sealed-enclosure sub. The increase in power seems to expose more midrange even at lower volumes (scooped mids are a common complaint with the pro 900s).
With the E17 – I was constantly adjusting the gain/bass/treble – always looking for the right fit. With the E12, I just set it, forget it, and enjoy the experience. The price difference between the two is negligible, if you have the chance to try them side-by-side I’d encourage it – as the differences (though partly subjective) are quite noticeable. For me, the E12 is a much better performer and coaxes more musicality out of the pro 900’s than the E17.
*I should mention that I have one of the late April/early-May E12 models with the new bass-control. I believe that Mike’s review was written with an earlier version of the Mont Blanc.
Mike
Good to hear that you’re getting good sound from the set up
Keith
Hey Mike !
Can you tell me the specifics in terms of pairing it with the LCD-2’s?
Interested in this amplifier, but must give myself a reason to buy it 😀
Thanks bud!
Dave Ulrich
From the review “Strangely though it powers the Audez’e LCD-2 and Fostex T50RP (and its
derivatives like the Mad Dog headphone) just fine, I didn’t feel the
synergy to be there.”
dalethorn
I finally ordered one of these E12s. I’ll be comparing it to the PA2V2, the Microstreamer, Audioengine D1, and Dragonfly mini-DACs, and the new v-moda verza. My E17 has gone off to a new user, so I won’t be able to make that comparison, except from memory.
George Lai
Hi Dale. I look forward to your review. I tested an e12 at a shop and noticed that the high gain was +16 DB. I guess Mike’s +10 in the article was a misprint (or time for some new specs, Mike). It’s a pity I didn’t have my e11 at the shop with me to do a comparison.
dalethorn
I haven’t put together a formal review yet, but it won’t have the depth of detail you see here. I’ll just do a compare to the low-priced PA2V2, and also the DAC/amp for i-devices, the v-moda verza. The verza is an unfair comparison of course, but I need to frame the features against known items higher and lower on the scale. Like the review here says, it’s a good clean portable amp that sounds great with WAV tracks, not as good with 320k CBR MP3s that I convert from my own WAV tracks. I was surprised how much difference this amp reveals between those WAV and MP3 tracks, but that depends on some things — how good the WAV track is, and how your source is connected – in my case from the ipod touch LOD. The other little surprise was the bass – playing with the bass switch OFF, I hear slightly better detail and impact than from my PA2V2, although the PA2V2 sounds as extended on the top end. Then the E12 controls boominess better than the PA2V2 – I have some tracks by Diana Krall from the Live in Paris concert circa 2002 that are quite boomy and the E12 makes them better.
dalethorn
I put a review on Amazon for the E12. Nice amp.
George Lai
Nice review.
Jack Knight
how fiio e12 compared to ALO national?
Mike
The ALO National is more laid back, smoother, bigger sound, and has a better bass body and impact.
Minh Hoang Nguyen
Hi guy, how fiio e12 pair with dt880 600ohms ?
Mike
Should be very easy to drive the Beyer with the Fiio. However I suggest getting a warmer amp like Fiio’s E7K
benbenkr
E09k vs the E12, which is the better pick? Portability isn’t an issue, as I will use this primarily at home.
Also, does the E12 have any noticeable EMI as was reported by a few?
Pandale81
Hi! How about mixing B&W’s P’5 with this Fiio E12 (iPod Classic 160gb source) Thanx a lot!! Good reviews around here!!
dalethorn
My personal opinion is the E12 would make the P5’s soft treble a little too dark, although it might be good for the bass.
Pandale81
Thax for the replay!! Any advice about the best dac for the P5? Thanks a lot
dalethorn
When the source is a 160gb iPod, the only DACs that would work (I think) are Apple i-device DACs like the v-moda Verza or Fostex HP-P1. But if you want an amp to use with the iPod that can also be a desktop DAC, the E07k or E17 would work.
Pandale81
Thank you much for your advices. My personal opinion is P5’s are a little dissapointing when you use them with the iPod. I’m not an audiophile but I always look for the best in “amateur” level. Maybe I made a mistake no taking the Bose’s QC15 but after spending 300€ in P5’s I think I have to use them until I get tired at all. Thanks
dalethorn
The P5 is a great headphone, and the unique design it has makes it that much better. And it has very good isolation, so it’s actually a good value I think. But, sometimes you could match a headphone that doesn’t have enough treble or bass with an amp that also doesn’t have enough treble or bass, and when both occur together, it can make the sound too thin or too soft. In the case of the P5, I think the best amps for a reasonable price are the E07k and E17, and the fact that you can also use them as a computer USB DAC. Those amps will be a good match for the treble, but even if they improve the P5’s bass compared to using the iPod alone, there will be better choices for bass when you’re ready to spend for a much more expensive DAC plus amp.
Pandale81
Nice advice! I’ll think about it and I’ll tell you my opinion if I buy one of those. See ya!
Mike
P5 doesn’t need amping, I’d just use it direct.
Thanks!
Nasih
hye. Would E12 pair well with Goldring DR150? My source is an Asus laptop, having a UD100 USB DAC.
Mike
I’d go for the E07K for the Goldring. Both as an amp and DAC.
Jean Charles
JDSlabs cMoy or this for the HD650? I’m curious to try SS..
Mike
Cmoy
Jean Charles
Thanks Mike
Mike
You’re welcome Jean. 🙂
Mark Kirwan
Great review! I was curious as to how well the E12 would work with Ultrasone Pro 900s as I am shopping for myself for christmas. I have been interested in getting into audio equipment and I decided to start out with the Pro 900s paired with the E12, hoping I didn’t make a mistake! Also, the source of music will be primarily from my iphone 5 and/or laptop. Thanks!
Mike B
Very good review Mike! – I have recently bough a pair of Denon AH-D600, which are fantastic phones especially at their lower price! – now I’m looking for nice portable amp – amp/dac up to 100 pounds – unfortunately options are slightly limited here in the UK… I’m just wondering if i should go with the E12 , E17 or maybe Epiphany EPH-O2 all 3 share the same price tag… My source is an Ipod classic
Any suggestions much appriciated! Thanks
Wong
E12 will make good pair with SR80i? Need some suggest for a portable amp 🙂
dalethorn
To connect an iphone?
Wong
with ipod touch 4g
dalethorn
Then yes, a good match – the Grado tends toward forwardness and a slight brightness, and the slightly dark E12 is a good complement to that.
Edit: BTW, get a FiiO LOD cable so you can use the LOD output to the amp.
Andrew Buckley
Hi from the UK. Great site and reviews. Just purchased some Musical Fidelity EB 50s and now getting interested in a portable amp to accompany them. The Filo E12 was something I was considering but not sure how it would get along with the EB50s. Do you have any comments? Recommendations for a good pairing?
Thank you in advance.
Aleksandar K.
Hello from Germany. I really enjoyed reading this review. I´m researching a lot and everything leads to the opinion, that the E12 ist the best for my uses. I want to get some extra power out of my AKG K267 Tiesto´s out of portable devices, like my smartphone. Currently an iPhone, but in a few days it will be the Galaxy Note 4. What are your opinion about the Mix of the E12 and the K267?
Thanks for help.
Headfonia_L.
Not too familiar with those headphones tbh
Alberto Martinez
Hi Mike, thanks for all of these fantastic reviews, and
sorry after reading all comments I don’t know if my question is answered (sorry if so, please indicate to me where I can see it).
At home PC Windows 7 or iPad mini -> DAC Audioquest DragonFly v1.2 -> Schiit Asgard 2 -> Senn HD600; and I am very happy listening Rock and Jazz through Spotify 320kbps and FLAC HD
When traveling iPad mini -> DAC Audioquest DragonFly v1.2 -> Senn PX-100II and very happy too, but sometime I want to carry my HD600 so, which option do you suggest for portable headphone amp, E12 Montblanc or JDSLabs CMOYBB for this:
iPad mini -> DAC Audioquest DragonFly v1.2 -> E12 or JDSLabs -> Senn HD600?
Any other portable headamp under $150-200?
Thanks a lot.
dalethorn
The E12 should be great with the HD600. It should also be more reliable and rugged for travel.
Headfonia_L.
Yup, E12 or the C5
Nickjan Glas
hello everyone.
I have been using this amp now for a couple months and I like to share my impressions.
I find the details very nice for such a low cost amp. Just been doing some golden ears training with the meridian explorer and after switching to the e12 as amp instead of the meridian internal amp, difficult to hear nuances suddenly were easy to distinguish. Especially the bass extension was very good and the higher frequency extensions were improved aswell.
That said, the mentioned forward midrange and the IMHO small soundstage (especially with crossfeed on) I find the biggest disadvantages with this amp (disregarding its low price in this respect). The meridian (my only comparable amp at the moment) is warmer and much easier to listen to.
All in all I like it most with top40 kind of pop music and least with classical, but this my be also because of the headphone pairing (B&O H6). All in all I find it to be a great low budget addition to my iPod. (with LOD).
In February I will get the slightly more expensive meijer corda quickstep and I have high expectations for that one. Also I ll be receiving the fiio X1.
With the corda classic at home, I can finally start doing some extensive listening and comparing. And then….. new headphone….
Headfonia_L.
Keep us posted Nick. The E12 is mostly a power package and ok for it’s price sound wise. It does manage to drive a lot of headphones though and it has earned its medals. The E12A for IEMs is much more musical in the midrange section and has a wider sound stage
Nickjan Glas
I’ll do that. I have to wait until february unfortunately and be patient, but then I ll be doing some extensive burning in and listening!
dalethorn
A self-powered amp should sound a lot different than the “amp” that’s part of a DAC that gets all of its power from the USB line.
Nickjan Glas
That’s what I am learning indeed and that’s where the quickstep is going to come in for my pc set-up (together with being the fiio x1 amp). Despite being an integrated usb powered Amp, I do like the meridian a lot.
Marko Icelic
Nice job on the review! I have this E12, with ipod nano 7 and AKG K 391nc. I was planning on Sennheiser hd 558 or 598? What do you think of investment and which is better?
Also, when time comes, I’ll switch from ipod to Fiio x5!
Greetings from Serbia Mike!
