I'm sure many are pondering about these two portable powerhouses. So this one is for you.
 
First off, some size comparisons: (taken directly out of camera without any adjustment whatsoever)
 

 

 

 

 
So, as you can see, E12 is almost roughly TWICE the size of C&C BH. Some people may say that E12 is still a portable amp, and... I'd agree. But seriously, it's still quite a big portable amp. It's noticeably thicker and larger than my iPhone 5. If memory serves, this means E12 is roughly twice the size of E11 as well.
 
In terms of build quality, both E12 and C&C BH are very solid. I'm confident that if I ever get shot, then either amp can take a bullet for me. E12 in particular is very solid and hefty.
 
And personally? I much prefer E12's design accent. Very professional, and almost too polite-looking. And no, it's not the black color. I think it's the monolithic uniform rectangular look.
 
But does size equal sound? Let's find out.
 
Here's the test chain:
Fiio D3 connected to my MacBook via optical cable, and then the output is connected via silver RCA cable to the amp.
 
Here's C&C BH:
 

 
And here is Fiio E12:

 
Both amps are connected to my two favorite headphones: Audio Technica ATH-ES10, and Audio Technica ATH-ES7. My dad's M50 gets a mention because I thought it might be interesting for those who are wondering about the bass-boosting capability of either amp.
 
Here are some individual song tests:
 
1) The Beatles - Here Comes The Sun: I'm handing this one to Fiio E12. No question. The sound out of E12 is not as articulated or airy as BH, but the midrange is very clean, concise, and warm. With crossfeed on, E12 gives an intimate, forward, but very layered presentation of the song, whereas BH is stuck portraying vocals to the far right side, and instruments to the far left side irregardless of what I do with the switches. In fact, SF on would make it worse as BH pushes the width of the song even further apart. It was like listening to the Beatles playing in a cave. Very weird feeling if you ask me. Meanwhile, it's emotional, intimate, and warm with E12. I think I get the gist of what Fiio is intending to do with E12 now. You throw E12 a pair of cans with lots of treble but slightly recessed midrange like the DT880, and I think you'll get quite a combo. Too bad I don't have a DT880 handy.
 
2) Michael Buble - Stuck In The Middle With You: and here's a prime example of how crossfeeding doesn't always work. This song is properly recorded for stereo listening, which means vocal is properly distributed between left and right channels, and instruments are well-spread between the channels to give a surround feel. Crossfeeding condenses everything into the middle in front, but... that makes this song feel too congested. Despite all that, I'm giving this one to E12It's hard to explain, but while lacking the soundstage and details of C&C BH, E12 gives Michael's voice more warmth, more... magic. Something about E12's presentation of this song sounds too right for me to ignore.
 
3) Eric Clapton - Tears in Heaven: crossfeeding doesn't work here, either. But I'm still giving this one to E12. E12 somehow gives Eric's voice more weight and more "soul"... whereas BH gives a less convincing projection of his voice. Not that I have actually heard Eric live to compare, but I like E12's presentation of his voice here better. Crossfeeding or not. Oh, and note that at this point, I've pretty much given up on Crossfeeding for songs that were recorded after 1990.
 
4) Combichrist - Never Surrender: this one goes to E12 again. E12 seems to portray vocals really well. BH makes the vocal too thin. Also bass has more weight and heft in E12. Even without bass boost, E12 has fuller bass than C&C BH with LF switch set to on. BH has more soundstage, though. Significantly more. But I don't think soundstage alone makes the song.
 
5) The Glitch Mob - Fortune Days: oh God, my opinion is very split here. I absolutely love, love, LOVE the way E12 portrays bass here. It's just perfect. Even without bass boost. BH sounds like a hollow pit in comparison. But... BH has the massive soundstage and clarity advantage here. Funny... but the smaller BH sounds "larger" than the bigger E12. I would love to have BH's massive soundstage but with E12's bass with this song. But since I can't have it both ways (more on this later), I'm making this one a tie. On a side note, for those interested: E12 + bass boost gives quite a lot more vibration for this song, but... personally, I don't like how it sounds.
 
6) Two Steps From Hell - To Glory: okay, I'm being unfair here. This song sounds very epic. As such, massive soundstage + clarity is an automatic win. It's not even a contest, C&C BH takes this one by a good mile. Still, gotta love that bass texture of E12. I really mean it. Still can't have it both ways.
 
7) Black Sun Empire ft. SPL - Wasteland: okay, I'm being unfair again. This song has a lot of bass, so obviously whichever amp does bass better and clearer would win. Fiio E12 takes this one... by a mile. C&C BH would clip fairly early, and bass becomes a muddy static when that happens. E12 doesn't clip... at all. I turned the knob up past the point where my endurance could take, and the sound coming out of E12 is still absolutely clean. Bass hits with authority and control the kind of which seems almost impossible for a portable amp.
 
8) Skrillex - First Of The Year (Equinox): urgg... bass. I don't think I need to say more? Fiio E12 takes this one, too.
 
9) Owl City ft. Shawn Chrystopher - Alligator Sky: this song has a lot of treble energy. As such, I admit that it's not fair for E12, since BH boosts treble and clarity by quite a lot. Still... despite all of that odd, E12 wins again here. I really, really, really can't overstate just how well E12 does vocal compared to BH. Even with the advantage of soundstage and treble, BH just can't pull that midrange away from E12.
 
10) Hatsune Miku Append - Mr. Wonder: I'm throwing a bit of vocaloid here for the curious. It's obvious at this point which amp I prefer, so it's kind of pointless to keep adding songs. Rather than that, I'd like to throw a freebie to vocaloid fans (I'm a fan, too). If you want a portable amp that can seriously project a life-like voice, then... E12 it is.
 
Sorry if I missed any genre up there. I obviously concentrated on just the genres that I like... mainly EDM and pop/rock. The result may be different for other genres. But... I personally know which amp I'd use more now. Fiio E12 does so many things right that I simply can't find any way that I'd prefer C&C BH over it. It's funny, actually, because up until yesterday, I kept thinking that Fiio E12 wouldn't be able to beat C&C BH... but... the reality is, it did, and it did so with style. The soundstage advantage of BH over E12 is actually not that big, by the way. E12 probably has about 80-90% the soundstage of BH. It's just without the treble and clarity boost of BH.
 
On that note, my memory is hazy, but if I have to rank Fiio E12 and C&C BH against other headphone amps that I have/had, it would be like this:
 
1) Fiio E12
2) JDS Labs O2 (no longer have this, so take this with a grain of salt)
3) C&C BH
4) JDS Labs C421 (no longer have this, so take this with a grain of salt)
5) cmoyBB w/ OPA627 (no longer have this, so take this with a grain of salt)
6) Fiio E11
7) Fiio E17
8) Fiio E10
9) Fiio E7
 
So yes, I rate Fiio E12 even above O2. O2 is more transparent, and somewhat cleaner, but if I have to pick an amp that I'd power ANY headphone with, I'd pick E12.
 
Edit:
 
Adding this for those interested: what about dual-amping from BH to E12? Best of both worlds?
 
Well, not really. The thing is that the LF and SF switch on BH seem to mess with the music enough that dual-amping to E12 sounds really... weird. It makes the presentation a lot warmer than it should be. It's even warmer than DAC -> E12.
 
What about the reverse? E12 to BH? Well, then the bass refinement is lost in the process, and midrange becomes congested rather than just... warm.
 
So no, not the best of both worlds.
 
Post-SF Bay meet edit:
 
I had some extensive comparison to O2, so the post is no longer between E12 and C&C BH. But because I don't want to clog the forum with yet another post of the very same topic, I'll edit this thread.
 
So, headphones that I plugged this combo into, with notes of which amp was the preferred one:
 
Audio Technica A900X - O2 (E12 adds too much warmth, and it makes the A900X sound congested, but note: A900X has a less open sound than my ES10...)
Audio Technica ES10 - E12 (more midrange body and bass texture with E12)
Beyerdynamic DT880 (250 Ohm?) - O2 (I personally prefer E12, but majority vote won out)
Beyerdynamic T5P (with custom cable and ? mods) - E12 (better bass control, and better midrange)
Ultrasone Edition 8 - E12
Hifiman HE-500 - O2
Audeze LCD-2 - O2
Sennheiser HD800 - O2
Grado GS1000 - O2
V-Moda M100 - E12
 
It seems like a close battle, but... the two amps are not even close.
 
O2 has a more even, balanced frequency response that doesn't favor any particular region. It's clean from top to bottom. Also soundstage is slightly bigger (width).
E12 has a warmer tilt to the midrange, and a bit more bass articulation (without bass boost), with less micro details. Also soundstage is slightly smaller (width).
 
Also I mistakenly thought E12 had more output power than O2. O2 has more output power than E12 in reality.
 
Personally, I'd still rate E12 higher than O2 because E12 fits well with my personal favorite (ES10). But if I had any of the other headphones, I'd go with O2 instead.
 
So... hope that helps. My only advice to potential owners of either of those amps is to look at what you're listening through and decide really hard whether you need more clarity, or more body to your sound.
 
Some more notes: O2 and E12 were plugged into either an ODAC, my MacBook, or my iPhone 5.
 
C421 comparison edit:
 
So... the story is, I traded my E12 for a C421 (AD8620) a few days ago.
 
And before my memory of the E12 completely fades away, here are some quick thoughts:
 
C421 w/ AD8620 is a lot cleaner than I remember. Maybe I had the OPA2227 version before. E12 sounds nowhere near as clean.
Instrument separation and soundstage are very good with C421. So much so that from what little I can remember of the O2 from... a few days ago at the meet, I'd say C421 "cleanly" beats O2. Yes, pun intended.
 
But does that mean C421 is better than E12 in every way? I don't think so.
 
For one, I still think E12 has more articulated and effortless midrange. There are times when C421 is just way too lush/smooth that details are lost. It's like listening underwater without the distortion. On overly gritty/grainy recordings, I think it's awesome, but on lush and smooth recordings, it does take away from the listening experience slightly. I think it may be dependent on the headphone, because I hear the smoothness more prominently with my ES10.
 
For another, I think C421's bass is flat. And by "flat", I mean... "someone kicking a cardboard box" kind of "flat". There is just no texture, no rumble, no weight, body, or anything to it. It has good impact, but I don't think it's anywhere near the level of E12. E12 does much better bass than this.
 
And last but not least, the bigger soundstage is not always appreciated. With my dad's vintage Pioneer SE-50, soundstage on C421 is so large that it's like listening to everything inside an opera house. With classical music, it's a treat, but it's a disaster with pop/rock/jazz music.
 
Other than those differences, it's pretty much the same as E12 vs O2. E12 is warmer, with less soundstage. C421 is cleaner, much more neutral, and has much larger soundstage.
 
I chose E12 over O2 because of personal preference, but this time? I'd say C421 and E12 are pretty evenly matched in almost every way. If I had a choice, I'd keep both amps, and use either when my mood hits. That's just how good C421 is to me.
 
On that note, I think C421 is superior to C&C BH in every way. And it's very "clearly" (yeah, pun intended again) a $189 value vs $100 value sort of superior.
 
So I'm revising my ranking up there:
1) Fiio E12 (that bass and midrange is too good for me to let go, I guess)
2) JDS Labs C421 (I'd say it's a tie with E12, so it's not truly 2nd place)
3) JDS Labs O2
4) C&C BH
5) Fiio E11
6) and the rest...
 
A very heartful thank you to SteveSatch for agreeing to the trade. Steve, I hope you are enjoying the E12 as much as I am enjoying your C421.

Nice review! I had a feeling FiiO would continue their streak of quality gear.

Thanks for the comparison review. I never bought into the C&C hype and this strengthen my opinion about it.

I don't think C&C BH was ever meant to compete directly with E12, more so focused as an upgrade from E11.

Awesome read! I'm soooooooo tempted to get the E12 0_0

 
Stock is quite limited on E12, so better jump on it fast!

Yeah, they had a winner this time. I couldn't believe what I heard, either.

To be fair, C&C BH is actually better than a lot of similar-sized portable amps, so I think the hype is justified.

I agree! It's just that E12 is doing so much better than E11 that it leaves almost everything else in the dust here.
 
If I were to do a C&C BH vs Fiio E11 review, the BH would obviously take the cake in every category.

Which output did you use for the BH? Did it make any difference in the comparison with the E12?

When there were vocals, I used Output 1. Otherwise Output 2.
 
But it didn't really make a difference. E12 just has much more refined midrange and bass quality.
 
I would actually believe it if Fiio claims they took apart an O2 and added more refinements to it. That's how much better E12 is.
 
Also, I don't think there was any problem with output power. All of the headphones used were around 30 - 40 Ohm (42 for the ES10, 38 for M50, and 32 for ES7), and they weren't particularly hard to drive.

damnit head-fi.

I already knew I was going to get an E12, but this just sold it.

I just ordered and Ultrasone Signature DJ and based on your comments regarding how well the E12 pairs with headphones that have forward treble and recessed mids, I feel I MUST purchase an E12 to do them justice.

Thanks for the info. This comparison really has me considering buying an E12 for myself. My BH just shipped out and should be arriving in a little over a week, but the fact that the E12 does more for the bass than the BH has me itching, especially since I feel they'd pair really well with my AD900X.

Woah you paid $190 for your BH?
Why. How.
 
Feb 2, 2013 at 1:53 AM Post #13 of 233
Whoa, wait, nevermind! i was thinking about my AD900X since I've been posting quite a bit about their price and mixed the numbers in my head... I paid the normal $99 for the BH from Pollychen.
 
Feb 2, 2013 at 2:55 AM Post #14 of 233
Oh okay, thanks for clearing that up.
 
I feel like the price-performance ratio for both of these amps is pretty incredible considering this comparison, and that the E12 is only $20 more. I thought the BH was good at $100.... But from this comparison it sounds like they're both different stroked for different folks. I mean, like H20 said, the BH has 80 hours battery which to my knowledge is unrivaled in the portable amp world. And they both have different strengths and weaknesses. I for one prefer sound stage over vocal presentation considering I listen to mostly drum and bass. 
 
I'm curious to compare the bass between these two on my M-100. I wouldn't say the LF switch muddies the bass on the BH, but it should also be noted that the LF switch also boosts highs a bit. If what you say about the E12's bass is true, It might be my go-to over the BH, but the E12 has a lesser bass boost at +3dB @ 80hz diminishing, and the BH is kind of unknown, but I'm certain it's more than +3dB but I have no idea what the frequency peaks and valleys are. 
 
I wish there was better solid information on the BH other than poorly translated descriptions making it seem like a sketchier product than it actually is.
 
Oh, I'm going to note that the BH's shape and size fit nicely in the hand, that flask-ish bevel is very ergonomic. But when it comes to build, I found the volume pot on my BH is crooked, it rotates on a slight axis by like, a degree (I'll post pics later in the main BH thread). This by no means is a fatal flaw as it functions entirely as it should. 
 
I still think this SF switch has some serious WOW factor to it. 
 

 
EDIT: I mentioned it in the main BH thread, but I meant to post it here; I think ti'd only be fair, for comparison sake, to do a three way between these the E12, BH, and C5. These three are either recently released, or recently praised in the case of the BH
 
Feb 2, 2013 at 3:14 AM Post #15 of 233
I'm truly curious to see how my AD900X will sound through the BH and E12. I'll get the E12 in a month probably after I've spent a good deal of time with the BH. The soundstage of the 900X is already pretty incredible, so I'm anxious to test how OUT 1 and 2 sound with SF on and off. I'm most interested in the bass boost as the 900X could use a bit more, even if they're not exactly anemic. Would be nice to see how my old 700 does, though.
 
Gotta say, the E12 looks ******* sexy, but the size of the BH looks a lot better. I feel I'll probably use the two amps interchangeably in the future depending on my mood.
 
If you do get the E12, Apo0th3karY, do post your thoughts on the M-100's performance with it compared to the BH! Thinking about purchasing those headphones in the future.
