  • MUSICALITY AND HEADROOM.

    SM 64 earphones were made to handle music of all intensities and all volumes on any device, absolute control of the audio spectrum, incredible stereo image and maximum headroom, letting you crank it up without distorting the sound.

    With is new HQ crossoving process with impedance corrector and drivers combination, the SM64 provide a equilibrate spectrum at any intensities that make it very musical and accurate. Having the same circum oral headphone comportment.

    Our R&D departement worked on delivering a new audio quality reference when SM64 is coupled with a additional nomad amplifier that push forward the listening experience with a universal model. The SM64 universal model result of all the R&D experience we learned developing our EM4 and EM6 custom models.

    REPLACABLE CABLE.

    We know that the cable will always stay the weak point of any earphones. That’s why we’ve designed our cable to make it resistant and also replacable.

    "The Ultimate In Sub $1000 Earphones"
    Pros - Superb sound signature (detailed, full & lush), stunning mids, terrific soundstage. Near perfect HQ crossover circuitry.
    Cons - Fit may take a few tries to perfect.
    I've now had these earphones for over a year and I remain breathless at how versatile they are. The below list should give readers of this review a good idea of the kind of sound I have been used to in the past as I have owned the following.

    IEM's:
    - Westone W40
    - Shure 530/535 SE (Red)
    - Sennheiser IE8/IE80

    - Etymotic ER-4S

    HEADPHONES:
    - Sennheiser HD 650
    - Sennheiser HD 580
    - Audio Technica ATH-W3000 
    - Audio Technica M50


    Just prior to buying the SM64’s, I had decided on the Westone W40’s. I'd heard great things about them and got them from an Australian online retailer at a reasonable discount with a money back guarantee if I wasn't happy with them. I decided on the W40’s over the SM64’s partly for price but mostly because of the fact they had four drivers, one more than the SM64’s which have a measly three. Four’s gotta be better than 3 right?

    Well – I've discovered that’s not always the case. It’s got to be said that W40’s are excellent earphones, and had I not owned the above mentioned earphones, would say they're pretty good. The problem with the W40’s is their almost complete lack of ‘fun sound’. They're detailed, cover the audio spectrum quite well, but ultimately, I just didn't enjoy them. I’d experience short moments of “wow” but these were few and far between. So I sent them back and with the refund, bought the EarSonics which took a real leap of faith not having tested them. I was compelled by all the extraordinary reviews I had read - reviews that still didn't do them justice.


    The SM64’s are never ever boring. Nor are they overly coloured. In fact I would describe the sound as detailed, fairly neutral – yet full, lush and way bigger than any IEM’s should ever sound.

    BASS
    I said earlier that reviews I'd read about the SM64’s didn't do them justice, mostly because some of them said that the bass wasn't particularly prominent. This couldn't be further from the truth. The bass from these IEM’s is something to behold. It’s definitely not boomy however it is full and beautifully detailed/textured, something I did not experience with the W40’s which had not one but TWO dedicated bass speakers in each ear! How EarSonics achieved this miracle is a true mystery, but they could have used sorcery for all I care – the bass is so fantastic that it’s addictive, such is the detail contained within each bass note. Not only is the bass clear and balanced, it extends low – very low. I’m talking subwoofer low. When listening to the opening scene of Batman The Dark Knight on Blu-Ray, I was treated to sound I'd only heard previously in the IMAX theatre I'd originally watched it in. You literally feel the rumble in your ears.

    MIDS
    Next is the mids which I can only describe as “buttery smooth” and just a delight to listen to. The mids are a little forward but have astounding quality. This is the key difference between the SM64’s and their closest rivals, the Shure SE 535’s – brilliant earphones that do a lot very well, but never quite come close to the class and “fun” of the SM64’s. To get the 535’s to sound their best, amplification is required to get to that “wow” factor. This is not the case with the SM64’s – all that’s required for great sound is an iPhone. Anything above that (whether it be amplification or player with better phone-amp stage) will scale the sound up from friggin' awesome to whatever superlatives you wish to place above that.

    Yes, these earphones are seriously THAT good. 

    HIGHS
    This is where EarSonics hit it out of the park. The highs are clear, detailed (really detailed) and much like the bass, also have that addictive quality where you want to listen to recordings just to hear what new details you had previously (but unknowingly) missed. 

    All three frequency ranges sound brilliant alone but it’s how they sound together that gives these earphones their magic. EarSonics obviously put a huge effort into getting the 'HQ crossover' on these earphones right, and they succeeded – spectacularly. It often feels like I have full sized headphones, not earphones on. 

    SOUNDSTAGE & INSTRUMENT SEPARATION
    Last but not least is the soundstage. Now THIS is where the SM64’s come into their own. You would be forgiven for thinking they had 5 or even 6 drivers per ear instead of 3. Even with lower quality recordings, the instrument separation is excellent. But upgrade to higher or full bit-quality sound and the separation (and soundstage) really has to be heard to be believed. Not one of the competing IEM's I have listed above come close, and they even gave the full sized headphones a run for their money. A huge statement, I know. But one I stand by.

    Much has been said about the impedance (which is a high 98ohms) but I had no trouble driving them from my iPhone 5S or my current iPhone 6 Plus. I do have to turn the volume up louder and much older recordings couldn’t be driven loud at all. But anything post late 90's should be fine. With amplification, this is not at all an issue. The SM64’s seem to have the right balance of impedance vs sensitivity resulting in great (though slightly reduced) volume - an issue instantly sorted with the use of a portable DAC (more on that below).

    GRIPES?
    So it can't all be good news, right? Well in the interests of balance, I do have some gripes. A minor one (that is now sorted) is the fit. The default eartips did not work for me. It took ages for me to get the right fit but even then, there was almost no bass. It wasn't until I changed to the slightly bigger ones that I almost instantly started experiencing audio nirvana! They're now virtually as comfortable as the Shure SE-535's which are considered by many one of the most comfortable IEM's on the market.

    My main gripe though is the build quality, notably, the slightly cheap feel of the plastics used. For earphones that cost over AU$500, I expect better. That said, perhaps this is EarSonic’s way of saying “hey look, we put 
    all our effort in making these earphones sound great and skimped a bit on the shell casing”.

    And maybe they're onto something as ultimately, I just don't care. It’s not like they're falling apart. They're very sturdy indeed and one year on, show zero signs of wear and tear despite the fact I use them all the time. They just don't look the million dollars I forked out for them which never matters anyway once I press that play button.

    RECOMMENDED USE WITH iPHONES
    Whilst the sound is great with the standard music app on the iPhone, I very strongly recommend using the Onkyo HF Player app which is free. The sound is dramatically improved with this app, especially as it has a "touch-adjustable linear-phase FIR equalizer, which offers 16,384 discrete bands of high-definition equalization with zero loss in audio quality". It offers an in-app purchase of the HD Player Pack for playback of multiple HD (192 kHz/24-bit Hi-Res Audio) formats including FLAC, DSD etc - which I recommend if you want to use any of these formats (that the native app doesn't recognise).

    I also strongly recommend the Oppo HA-2 portable amplifier. Not only does it look amazing (in my opinion the best looking portable amp with its leather exterior) but the sound it creates when coupled with the SM64's is outstanding as it has the ability to use the digital signal from the iPhone via the lightning port.

    FINAL WORDS
    If you're after the ultimate in sub $1000 earphones, you would be hard pressed in my opinion to find anything better than the EarSonics SM64’s. They deliver brilliantly time and time again and outclass headphones that cost notably more. The instrument separation and soundstage (for an IEM) is superb and all three drivers produce outstanding, beautifully balanced and addictive sound. They sound so good, I'll no longer be using my full sized earphones. Finally, an IEM that rules them all! To get anything noticeably better, you would need to spend almost triple what these cost. There's a reason why so many reviews recommend them so highly, and now that I own a pair, I know exactly why.
     
    So if you're tossing up between the SM64’s and their competitors take it from me, sonically (and in terms of value and music versatility), the SM64’s are king!

    "Absolutely Magnificent IEMs. Endgame without an endgame price. "
    Pros - Sound quality from top to bottom
    Cons - Build quality
    THE RATINGS:
     
    Highs: 4.5/5
    Mids: 5/5
    Lows: 4.5/5 (probably would be 5/5 with amping)
    Bass: 5/5 (swooshy style, though)
    Value: 5/5
    Soundstaging: 5/5
     
    This is all to say that the Earsonics SM64s are perhaps the best IEMs I have ever heard, and I was always a big IEM person. 
     
    Let's be short about this:
     
    It absolutely slaughters the Shure SE530, SE535 line (which was an old-time favorite for me). It also is a large improvement over the famed Earsonics SM3s.
     
    When I first received the SM64s, I was extremely disappointed. The sound was really bad. The sound was very muddy, the bass was extremely bloated and overbearing. There was a lack of energy everywhere along the spectrum. In my quest to figure out what was wrong (I didn't want to buy Westone 4s either; I had already spent so much damn money), I went out and busted $25 on Shure yellow foamies. The sound increased by maybe 10%-15%, but it was still bad.
     
    Having owned the Sm3s, I suspected that it had to do with the filter located in the spout of the IEMs. However, as a fairly new product that isn't nearly as popular as the SM3s in terms of name, no one had really jumped the gun to modify their SM64s and take out the filters. One evening, in a rage about how bad my SM64s sounded, I said "screw it, let's take 'em out." So, I took out the filters.
     
    The sound changed 100%. The IEMs sound NOTHING like they originally did with the filters. Now, it became the *best* IEMs I have ever heard:
     
    SOUND
     
    It is extremely transparent and clear. Everything has remarkable resolution. The last time I heard this resolution was when I had the UM3Xs, but the UM3Xs just aren't as good as the SM64s overall. I thought that in order to get technical prowess, you'd have to give up musicality. Somehow the SM64s seem to have reached this godly plateau of high technicality and good sounding music. It has a perfectly transparent sound. I can't even say that it's very colored or warm; it is almost perfectly neutral.
     
    The SM3s sounded super fun, but they were very siropy and thick. The SM64s sound nothing like the SM3s in that way; they have fantastic detail from top to bottom. 
     
    Soundstaging is great; for IEMs, the SM64s have a large soundstage. It does not sound congested at all. It's a perfect balance between spacious and intimate. Like I said, it's perfectly neutral; everything about this IEM is just spot on. 
     
    This is giving me problems describing the sound, because there's nothing else to say except for it's completely neutral and spot on. Maybe it leans slightly more intimate than spacious, but really, it is in such stellar balance that people used to SM3s or SE530s might call these spacious. It's just perfectly situated.
     
    It is a perfect balance between forward and laid back. If I had to compare with my big cans, it occupies the middle ground between my LCD-2.2s (which were very forward) and my HD650s (which were so mellow you wanted to fall asleep). This sits right in the middle of the two; it's forward enough to be fun, but doesn't stress you out. It's laid back enough that everything sounds effortless and easy-going, but without rocking you to sleep and coming off as without energy.
     
    I seriously struggle to imagine how a universal IEM gets any better than this. I got to try out some AKG3003i for a few minutes at a fellow HeadFiers house, and from what I recall, these sound just as neutral as the 3003is. Maybe the 3003is had a larger suondstage and the SM64s are a tad more intimate, but these sound so transparent. There is absolutely NO veil; you hear everything with remarkable imaging and clarity.
     
    Bass quantity was reduced upon taking out the filters. But it's still very much there, and will satisfy anyone who's not an explicit bass head. Bass is more than the SM3s and extends deeper. I don't care that much for bass, however, so this is not that important to me. It has a swooshier sounding bass, however. I think the UM3X punch is better, but some people like the more laid back swooshy sounding bass. This is just personal preference.
     
    Instrument separation is good; it doesn't rip things apart, but it's definitely articulate. For instance, the UM3Xs rip things apart, whereas these bring them apart enough to appreciate every string, but is smooth enough to give a coherent sound.
     
    Weakest part of the sound is probably the highs. Maybe could do with a tiny bit more energy, but only at the risk of becoming fatiguing. The lows also could also use a little more power. Remember, though, my entire test has been unamped. I reckon if these were amped, the lows would have enough power, and perhaps all my super minor suggestions would be satisfied. 
     
    COMPARISONS
     
    SE530s/535s: These eat the SE530s alive. Sonically, it is just better in virtually every way. It has greater technical ability and is clearly superior in virtually every way, except for maybe vocals (which the 530s are just beautiful at). 
    UM3Xs: The SM64s is perfect for any fan of the UM3X (like myself) who still has a few qualms with the UM3X sound. This is basically everything you wanted your UM3Xs to do. Good separation, very high technical ability, transparent, but not cold, flat sounding. 
    SM3s: Better in every way. The SM3s are veiled and muddy; these are not at all. The SM3s were good generalists, but if you listened to carefully, you knew that the mids weren't as good as the others. You knew the highs were rolled off, and resolution was lacking. The SM64s, I'm not sure what tops them (especially at this price range).
     
    TIPS
     
    Tips on tips. Well, I am using the Westone star tips right now, which reduces bass quantity a bit and makes everything sound a little brighter. However, I only am wearing them because I can't be bothered to start burning through my Shure yellow foamies just yet. I think the best tips for these are the Shure yellow foamies, followed by the Westone stars. Everything else sucks (especially the ES complys).
     
    CONCLUSION
     
    Whoops everything in its price range; I think it can contend with the super expensive universals. I honestly have no intention of buying other IEMs ever again, unless there's some serious new technology that comes out and blows me away. If I am to upgrade, it would have to be up to the likes of the Shure 846s, which I've not yet had the pleasure to listen to, or customs. 
     
    Happy listening.

    Pros - Excellently crisp sound, good low-end detail, generally sweet midrange
    Cons - Cable could be better, finish quality is not perfect

    I've been a fan of Earsonics since the SM2. Then the SM3. I found the SM3 to be almost perfect and the SM2 to sometimes be too dull. Actually, the SM3 had a similar voice. 
     
    SM64 came along and surprised me.
     
    1: it looked exactly like the SM3, even down to the accessories
    2: it sounded way better than both the SM2 and SM3
    3: it rarely hisses, and when it does, it is because the source is either too powerful or is absolute crap.
     
    Numbers 2 and 3 are absolute killer points for the SM64. And number 3 really pulls straight into number 2. 
     
    With an impedance of 98Ω, the SM64 puts no current stress on any portable player or microphone box. The only stress is if the source can spit enough voltage out. The answer is that most players out there can. In fact, at 122dB sensitivity and 98Ω, the SM64 is the perfect earphone. It hits the sweet spot because it never needs an amp. If you plug it into an iPod, it will sound the same as if you plug it into a DX100, that admittedly, has far better output. 
     
    The SM64 is the great leveller of gear. It presents almost no load to even awful outputs. Amazing. Again, if your source is absolute crap (having very little voltage in its output) the SM64 will be too much. But I've yet to find a single source that can't make the SM64 sing perfectly. The sources I use are:
     
    - iPod shuffle 1G (512)
    - iPod nano 6G
    - iPhone 5
    - iPhone 4s
    - iBasso DX100
    - iBasso DX50
    - Fiio X3
    - iRiver AK100
    - Sony A828
    - iMac
    and more.
     
    Each one sounds great, has no hiss, and is balanced along all frequencies. The only other earphone I can say the same for is the Tzar 
     
    Sound
    I'll not go overboard into details here as I'm tired. I wrote a long review at Ω image. If you want, you can check that out.
     
    Crispiness and space
    These two were somewhat lacking in previous SM earphones. The SM2 could throw a large stage, but its rather dull upper mids and lower treble compressed the stage. The SM3, too, had a somewhat subdued upper mid range that tended to darken the sound. It however was a big step up. The SM64 stands firmly between the SM3 and a truly bright earphone like the Audio Technica CK10 (which I love still).
     
    It has very good mid to upper bass response. Low bass <70Hz is audible, but not at all emphasised. It is a very good balance. Mids are bright and generally well balanced. Lots of detail to be had and also  lots of stereo separation. Very impressive. Slight suckout in the range of female vocals and upper violins dulls a very small portion of the music, but it is minimal at worst. Sound is overall excellent. 
     
    Again, I went into more detail at Ω image.
     
    Why is this the BEST stage monitor?
    Previously, I had labelled the Sensaphonics j phonics the best. I believe that at the time it was. The j-phonics had a sturdier body than did Earsonics. It also had an easier to drive load. Today's SM64 is easier to drive, less prone to hiss, has removable cables, and a stronger body. Its (with some quibbles) flatter sound is also better for monitoring applications. I would be happy if Earsonics upgraded their stock cable and used deeper sinks in their cable-earphone connections. But I think they won't be the ones to change the par for this course.
     
    All around a great earphone that is fully recommended. Its killer features: flat sound with good upper frequency energy and high resistance make it a winner that doesn't need an amp and plays well from 99% of the sources out there.
