Campfire Audio Andromeda In-Ear Earphone Review

11

Sound analysis.

Everybody has their own personal sound preference, and after a while I almost gave up on being able to find one pair of in-ear monitors that going to come close to balancing out a warm natural sound and a more revealing reference sound.  I always separate headphones into these two groups and analyze which one comes closer to my target preference signature.  Here, Andromeda was able to close the gap with a nearly perfect yin-yang balance of revealing detailed sound wrapped in a blanket of smoothness and coherency.

After a few weeks of continuous listening and going between PAW Gold and Opus#1 as my two primary sources, I found Andromeda to have a balanced revealing signature, with a slight hint of being mid-forward, and a very smooth natural tonal characteristic.  The signature is actually a good example of W-shaped balanced sound where lows, mids, and highs stand out and equally grab your attention.  You can easily shift your focus and effortlessly zoom in to distinct parts of the spectrum.  But as I mentioned already, the most important characteristics of Andromeda sound quality is being able to successfully bridge the gap between warm smooth and revealing detailed tonalities, resulting in a perfection of a smooth organic transparent sound with an impressive clarity and retrieval of details.

Starting with a bass, you hear a bottomless low end extension with a visceral sub-bass rumble that has a warm textured quality.  Here, the tuning doesn’t shy away from a slightly enhanced quantity, but surprisingly it doesn’t overpower the mid-bass or turns Andromeda into L-shaped basshead monitor.  I hear a deep analog sub-bass layered underneath of a fast tight punchy mid-bass.  Bass is well controlled with an excellent separation from the mids.  In some cases, I found other multi-BA headphones with lows tuned like analog dynamic driver, while here it’s a combination of what sounds like a warm lush dynamic driver sub-bass with a fast balanced armature driver mid-bass – coherent and in unison.

Mids are another star of the tuning where lower mids have a natural organic body, not too lean but with a little bit of thickness and absolute zero muddiness.  That was another pleasant surprise because in a number of other IEMs I tested in the past, bass enhancement with a little thicker lower mids can take away from sound clarity by introducing some muddiness.  Here, it was carefully tuned without affecting sound clarity.  And speaking of clarity, the details of upper mids are very impressive.  It wasn’t exactly on a crunchy micro-detail level, but very close minus the crunchy part – very smooth and organic retrieval of details without a hint of harshness.  I especially enjoyed the vocal performance, both male and female, which had such a natural and realistic tonality.

Treble is bright and clear, with an excellent definition, zero sibilance or graininess, not too crunchy or super airy, but it still extends nicely and has just a perfect amount of airiness to lighten up the upper frequencies.  If you are a fan, for example, of extended crash cymbals, you are not going to hear the full extension of the decay.  I guess something gotta give, and I’m perfectly fine with it, though Andromeda treble performance is still ahead of many other smooth signature IEMs I’ve tested.  Again, as I stated before, I’m very impressed with clarity and transparency of these IEMs considering now smooth they sound.

The soundstage expansion is definitely on a whole other level with a real holographic 3D imaging where the width/depth/height parameters are way above the average performance.  It results in a relatively accurate placement of instruments and vocals in space, but at the same time in a few of the tracks with extreme panning of sounds it felt even a bit overwhelming.  Andromeda is great not just for listening to music but also for watching movies or playing video games with surround effects.  It picks up every little nuance of the random noise, places it perfectly in space, and gives it a new dimension.  Even so separation of instruments and vocals was really good, the layering was just Ok.  But I still found the sound to be very dynamic and transparent.

Comparison.

Andromeda vs 64 Audio U12 – U12 soundstage width is a little narrower, while depth/height is the same.  U12 has a bit less sub-bass quantity with B1 filter which actually gets closer to with S1 filter, mid-bass punch is very similar though Andromeda has a little more speed.  Lower mids are very similar, while Andromeda upper mids are brighter and more detailed where U12 is warmer, and not as forward as Andromeda.  Andromeda treble is a little brighter, with a slightly better definition and more airiness.  One of the biggest differences here is Andromeda being more transparent, faster, and with a little better retrieval of details while U12 is smoother, more organic, more laid back, and warmer in comparison.

Andromeda vs Noble K10UA – soundstage is similar in depth/height, but Andromeda is noticeably wider.  Andromeda has more sub-bass, while K10 has a faster mid-bass, both have a well controlled low end.  K10 lower mids are leaner, while Andromeda upper mids are smoother and more organic in comparison to K10 which can get a bit harsher and brighter.  K10 treble is brighter and has more crunch, and with a bit more airiness.  Andromeda sounds more natural smoother, while K10 is more revealing.

Andromeda vs UM Maestro – Maestro width is a lot narrower, while depth/height are very close.  Maestro sub-bass is more rolled off, while mid-bass punch is as fast but less aggressive.  Lower mids are a little leaner, but not by a lot, upper mids in Maestro are brighter and little harsher in comparison.  Treble in Maestro has better extension and also brighter and with more crunch and airiness, which could even feel a bit grainy in comparison.  Both have a detailed clear sound, but Andromeda is a lot smoother (not warmer, but smoother) and has a more natural tonality without any graininess or harshness.

Andromeda vs Noble Savant – Savant soundstage width is a little narrower, while depth/height is the same.  Savant sub-bass feels more attenuated and mid-bass punch is a lot less aggressive.  Lower mids in Savant are just a touch leaner while upper mids are very similar, being detailed a little more forward, but also a little brighter in comparison. Treble has a similar definition and airiness, but Savant has a little more crunch.  Overall Andromeda has definitive upper hand in bass, and sounds smoother and a little more organic in comparison.

Andromeda vs Westone ES60 – ES width is very close, but not 100% as wide, the height is the same but with a little less depth.  Sub-bass and mid-bass in ES are more neutral in quantity and don’t extend as deep or punch as fast or have the same impact.  ES lower mids are a bit leaner, but not by a lot, upper mids are very similar, maybe with Andromeda being a touch smoother and a bit more organic.  Treble is also very similar, clear and well defined without too much airiness.  Both have great transparency, but ES is more reference quality with a slight advantage in retrieval of details.  Andromeda is more balanced and a little smoother, with a more lifted low end.

Andromeda vs Westone W60 – soundstage is similar in comparison but W60 is a bit narrower, while depth/height is the same. W60 bass is slower and looser with a bit of spillage into lower mids, and thicker lower mids and smoother/warmer upper mids, also less sparkle in treble.  Andromeda is smooth, but faster, tighter, and with a more articulate bass and better control/separation from mids, leaner lower mids, more revealing detailed upper mids, and more sparkle/airiness in treble.

Andromeda vs Inear SD-4 – SD4 soundstage is narrower, while depth/height is the same.  Due to a more mid-forward sig, it feels like SD4 sub-/mid-bass are lower in quantity, but it could be just the case of sound signature difference.  With that in consideration, SD4 sub-bass is a little rolled off and mid-bass is not as fast.  Lower mids are very similar, while upper mids are brighter, a little more revealing, though a bit harsher in comparison.  SD4 treble is brighter, crispier, with a better extension and more airiness, but at the same time a little harsher, in some tracks even pushing closer to sibilance threshold.  In general, Andromeda is more balanced, smoother, with a deeper low end impact, while SD4 is brighter and more analytical and with a more enhanced top end.

Pair up.

As I was going through a pair-up with different sources, the main focus of this test was to compare hissing level, overall soundstage expansion, general sound quality, and the quality of low end impact.  I didn’t focus on more detailed aspects of the sound analysis, and instead chose what I found to vary the most between different sources.

LPG (Lotoo PAW Gold) – low hissing; the sound is very spacious, detailed, transparent, fast/punchy, with a natural tonality. I hear a strong mid-bass and textured sub-bass.

Micro iDSD (dac/amp) – no hissing due to a highly configurable gain setting (Micro rocks in this regard!); the sound is very spacious and detailed, has natural organic tonality, and excellent low end extension.  Reminded me a lot of LPG performance, maybe even better.

Samsung Note 4 – some hissing; good soundstage, detailed, smooth, fast sound with surprisingly great natural tonality though a bit warmer in comparison to other sources, and the bass is not as articulate.  Still, a good pair up on the go with a smartphone.

L&P L5Pro – some hissing; good soundstage, detailed punchy smooth sound, a bit bright and with rolled off sub-bass.  Actually, I wasn’t too crazy about this pair up, kind of caught me by surprise.

theBit Opus#1 – low hissing; very spacious, detailed, highly resolving organic sound quality, beautifully textured bass with a nice mid-bass punch.  Definitely among my favorite pair ups in this group.

iBasso DX80 – some hissing; good soundstage expansion, sound is warm, smooth, detailed, but not super resolving, more on a warmer analog side.  I’m on a fence with this pair up, it was a bit too smooth for my taste.

A&K AK120ii – no hissing; very nice soundstage expansion, detailed, fast/punchy sound, slightly rolled off sub-bass, a bit more mid-forward signature.  Zero-hiss sound in comparison to all of my other DAP sources, and I expect the same with other AK models.

FiiO X7 w/AM2 – faint hissing; not bad soundstage, very detailed balanced sound, smooth tonality, nice punchy mid-bass and good sub-bass extension.

Cayin N5 – hissing is high; good soundstage expansion, very balanced detailed sound, excellent low end performance, actually I found both sub-bass and mid-bass quantity/quality to be on a level of LPG, very punchy detailed sound.  With an exception of hissing, this pair up was actually good.

FiiO X5ii – faint hissing; good soundstage, excellent low end performance (sub-bass and mid-bass quality is really good), excellent punchy sound.  Definitely a pleasant surprise, X5ii pulled through with a really good pair up.

ThinkPad T430s laptop – pretty bad hissing; sound was too thin and bright with poor low end performance.  I didn’t expect a miracle and only tested it because my laptop was paired up with Micro iDSD already.  Straight from HO of my laptop, which has a generic sound chip, I found the pair up to be rather underwhelming.

Also, for the test purpose, I tried driving E12A and Q1 portable amps from LO and HO of LPG, and found E12A to be dead silent while Q1 yielded some hissing.

Conclusion.

I learned my lesson not to label any IEM/CIEM as the endgame headphones, because every time I think I found one – another review pair gets into my hands/ears and I have to eat my own words.  One thing for sure, CFA Andromeda was the biggest surprise for me so far in 2016, and it will be a tough act to follow.  With its warm, smooth, revealing tonality and a perfectly balanced sound signature, including the holographic soundstage expansion, Andromeda didn’t just get a checkmark next to all of my personal sound preferences, it quickly got to the top of my favorite in-ear monitors list.  As a mentioned before, nothing is 100% perfect and there is some room for improvement, but it’s related to a combination of the fit and my personal ear anatomy.  Once I found a pair of eartips that slightly extended the nozzle insertion, it resolved all the previous issues I had with a comfort of the fit.  Now, I’m really curious what Ken is going to come up with next.  If it took him less than 3 years to build flagship Andromeda and other CFA models, how can you top that?  Hopefully, we will find out in a near future!

    Hello, Twister.

    Great review always.

    I believe that you reviewed FLC8S in the past. May I know how FLC8S compare with Andromeda? If I understood correctly, FLC8S is slightly v-shaped so a bit lack of mid but Andromeda has great mid as well as high but less bassy comparing with FLC8s. Is this correct?

    For accoustic, folk, and female vocal, is Andromeda noticeably better than FLC8S?

    Thank you 🙂

    How does this compare to the Earsonics Velvet in terms of bass quality and quantity, as well as clarity ? Thank you Twister

    • twister6 on

      Sorry, I don’t have Velvet. But if I get a chance to review it, I will make sure to compare it to Andromeda.

  3. Chris on

    Thanks for the review. Quick clarification. Is faint or low hissing quieter?

    • twister6 on

      Good question, Chris. I’m rating it as: no hissing < faint hissing < low hissing < some hissing < high hissing.

    good review ,
    I have 2 Questions : 1-how is the sound compare to other ciem roxanne, noble 10,se5 Ul…etc
    2-Did you get them for free ?

    • twister6 on

      Sorry, I never had a chance to listen to roxanne or Se5, but I did post in my review comparison to K10 Universal Aluminum (which supposed to be brighter in comparison to what I read about K10 ciem). Plus, as you can see, I also included comparison to U12, ES60, Savant, W60, Maestro, and SD4, so you can get a good idea of sound performance through the comparison.

      Regarding the review sample, just like many other headphones I reviewed on head-fi, they are sent to me in exchange for my honest opinion, and I continue using them in a long term testing and review comparisons. No, I didn’t pay money for them. Yes, they are still a property of manufacturers who kindly offer these products for testing and reviewing.

        What is it with these sorts of comments lately? Almost sounds like a darn witch hunt :/ And you very clearly posted in the beginning that they are samples.

        I was reading another review where some reader was bitching that its not fair the reviewer gets it for free, the industry is broken blah blah and that its a whole grand conspiracy. Sounds like butthurt fanboys to me lol.

        Fantastic review as always Twist 😉

    • Tamal on

      Did you bother to read the review? He clearly compered to the Noble 10 lol. Judging by your second question its clear you didn’t read further than the first three lines -_-

      • YooAntoo on

        it’s just 1 question. why are u angry ? calm down , I just bought one and it’s good actually it’s better than most of my ciem .
        I was in hurry to order one and you are right I read the sound analysis but not the comparison .
        also I miss the score points the other reviewer was better for me,, this week I ordered se5 Ul. hope it’s the best ciem , cuz I’m tired of so called Total ciem ,they all good but not good enough to keep them and many were overpriced : I tried many fromm the roxanne, K10, harmony 8, Adel u12,layla, akg3003,shure se846, Sony Z5 ,Zues .
        I ‘m only left with 3 iem right now and still searching .

        • Jim on

          Isn’t 3 enough? I wish I can have at least one of those top tier iem. 🙂
