Tralucent Audio Ref 1


Headphoneus Supremus
Pros: Addictive sound, Bass that has no place being in an iem, Out of head sound, sounds... Real
Cons: Sound sig wont be for everyone, too much bass for the feint of heart, pricey
Hi all,
I will prepare a proper review when I have some time and am not working.
In short however, these are superior to any IEM I have personally used for my tastes.
I listen to a vast range of music, but in particular live rock/acoustic/prog rock.
There is nothing like listening to Alice in Chains unplugged or Dream Theater and you can literally close your eyes and believe you are there.
These are nothing but disjointed thoughts at this stage, however as above, I will construct a meaningful review when I have a moment.


Headphoneus Supremus
Pros: Deep quality bass; deep and wide soundstage; great timbre on the mids; controlled trebles; great speed; musical signature
Cons: Needs 200+ hours burn in; ruthless in revealing weaknesses in the music or source
Prior to owning the Ref 1, Tralucent Audio was primarily known to me for it Uber cable as well as its silver/gold cable. I own both cables terminated for Fitear customs.
I have had the Ref 1 for more than a month now. I opted for the Ref 1 to come with the Uber cable. The Ref 1 does in fact get better beyond 200 hours of use. There is no doubt that even before it is burnt in, the Ref 1's bass will wow the first time listener. However, with burn in, the timbre settles down and the quality of the bass shines through. And the Ref 1 is wonderfully musical.
Technical Details
As explained in AnakChan's review, the Ref 1 employs a pair of 9.2mm dynamic drivers in an isobaric design, together with a pair of balanced armature drivers. It is a 3-way, 4 driver, hybrid and isobaric IEM.
First Meeting with the Ref 1
The first time I heard the Ref 1, the thing which struck me was that bass - it was visceral, it was persistent and there was such deep sub bass which had no business in an IEM! But what struck me was that at the same time, the bass did not obscure the details or layers in the acoustic vocals I was listening to. And then when the bass was called upon, it hit and it hit hard. 
Although I am proud of myself that I overcame my initial panic and scrounging around to see if I had enough cash on me, and did not buy it immediately, I did eventually succumb.
Build Quality & Comfort
Prior to this, I had for the most part foresworn universals. Hence, there was some apprehension on how the build quality and comfort would be. I was pleasantly surprised that it was really quite comfortable with the Ortofon tips which came with the Ref 1. I did subsequently switch them out to Spin Fit tips which did fit my ears a little better. The housing of the Ref 1 sat in my ear quite nicely - they did not stick out and sat nicely against the conch of my ears.
As for build quality, there has some sweeping statements about number of users facing build quality issues. For myself, I cannot say that I have faced any thus far. Coming from Fitear customs where the build quality is par excellence, I do not find any occasion to have any complaints in this department.
The Uber cable is one of the best cables around. Much has been made of its ergonomic issues. While I do not go mountain climbing with the Uber, I must say that the fuss is a little overstated. Of course, it is everyone's prerogative if they place more emphasis on aesthetics or whether they simply want a cable that gives the best sound quality.
Music Genres & Sound Quality
As has been noted in my previous reviews, I'm an equal opportunist when it comes to music: as long as it is good music, I will listen to it. My music library currently stands at just under 12 TB and, according to JRiver, I have enough music to play continuously for the next 1.87 years before I run out.
What I find amazing about the Ref 1 is that, while everyone can rave about its bass and what quality there is once it is properly burnt in, it will do just as well with acoustic vocals, pop era, jazz vocals, piano music, strings or Mandopop. All because the Ref 1 has an almighty bass kick does not mean it is warm and veiled like some other IEMs that claim to have quality bass. The Ref 1 remains transparent and detailed. The Ref 1 is also very quick: it keeps up with some of the trance music I have in my library thanks to Awry. It also keeps up with groups like Keane and renders the piano so true.
While the Ref 1 shares its wide soundstage with its older sibling, the 1Plus2, the bass adds a dimension that most IEMs cannot compete with: a truly 3D soundstage. The Ref 1 has a very deep soundstage which enriches the entire listening experience. The bass gives body to the music and renders it more realistic. 
I do appreciate that the mids have great timbre, especially when strings are involved. It never fails to send shivers down my spine when I listen to YoYo Ma playing the cello on the OST of Crouching Tiger, Hidden Dragon. Vocals are also rendered very well indeed.
I do own some quality full sized cans. And I will confess that often times I actually forget I'm listening to an IEM rather than a full sized can.
There is one word of caution, however: the Ref 1 is quite ruthless about showing up the shortcomings of your music or your DAP. In that sense, it is very revealing.
I have a modest collection of DAPs (I can hear my friends sniggering already...) and I have heard them with the Ref 1. What I will say is this: the Ref 1 does actually benefit from the driving power of some DAPs like the Hifiman HM901 and HM802, as well as the Calyx M. Of course, I do enjoy the Ref 1 off the balanced output on the AK 240 where you do get astounding details and separation. Those of you who own the divisive Tera Player will be happy to know that I think the Ref 1 is a even better match with it than the 1Plus2. 
For myself, I thank the day when Spkrs01 persuaded me to take a chance on the Ref 1. I went in with an open mind and I have been rewarded by the realistic and rich signature of the Ref 1. I agree with AnakChan: the signature of the Ref 1 is unique and not heard anywhere else. Not everyone may appreciate such a realistic portrayal of music, but it is something which has to be experienced at least once.
"Vast" is spelt like this, Kiat. Not "modest" like in the second last paragraph. Haha.
Great review again. =] 
@awry, it is a modest collection of DAPs compared to the staggering amount of IEMs, headphones and what not that Kiat owns. 
Anyhow, really awesome review, Kiat. I can never write in such a fluent and superb manner.

Pros: Wide soundstage and unique presentation, does what it does pretty well.
Cons: Cable gets loose easily; fit, sound signature may not be for everybody. Price.
Tralucent Audio Reference 1 – With Comparisons


I would first like to give a huge thanks to Head-Fi member, warrior1975 for loaning me his Ref. 1 and TWau cable for review.  I was interested in hearing what the hub-bub was all about regarding the Ref. 1.  I was interested further because most people who have heard it either love the musicality of the Ref. 1, or they do not like the musicality - there never seems to be any middle ground.  After listening to the Ref. 1, I now understand both sides of the opinions.
Here are some quick specs regarding the Tralucent Ref. 1:
Driver used: Isobaric/dynamic
(two dynamic drivers sealed moving in tandem in the same direction)
- TWFK BA drivers
- Filter less system
- Proprietary silver/gold internal wiring especially developed for the Ref. 1
- Smaller Shell
- JH/2 pin connectors
- 26.8 Ohm Impedance
Here are the prices of audio equipment used in the review:
Tralucent Audio Reference 1 With Stock Silver/Gold Cable:  $1,698 (purchased for $1,650)
Whiplash Audio TWau Reference Gold V3 (Silver) Balanced Cable:  $525 (purchased for $500)
Whiplash Audio TWau Balanced to SE Adapter:  Free with TWau Balanced Cable
Link to New Whiplash Audio TWau Reference Gold Plated Silver:  $525 (not used in review)
MEElectronics Eartips Combo Set:  ~$10
Shure SE846:  $1,000 (or lower if you search online)
Headphone Lounge FBI Reference Silver Litz Cable:  $220 (or less/10% discount for repeat customers)

Sensaphonics Custom Sleeves:  $150 (not including impression and upgraded color fees)
Westone TRUE-FIT and STAR Combo Premium Audiophile Eartips:  $14.99
iPhone 6 (Space Gray, 128GB):  $849.99 or $399.99 with a 2-Year Contract
Software Applications Used
Spotify Premium – Extreme Setting and Neutron Music Player - both for the iPhone
Tweak Mentioned in the Review
The Shure SE846 modded black filters.  The SE846 comes with black filters, and the stock black filter (warm) sounds too warm to my ears compared to the stock blue (neutral) and white (bright) filters.  Removing the foam damper from inside of the black filters results in the sound retaining the lushness of the black filters, but adds the benefit of the foam damper-less white filters.
Packaging and Accessories
The Ref. 1 comes with a Tralucent box, another Tralucent felt-like box, pouch, tips, a cleaning brush and a mini (3.5mm) stereo jack to ¼-Inch stereo jack adapter.  Thanks to warrior1975 for sending me the four pictures of the box and tips in the boxes, shown below:
Here are pictures of the boxes with tips and various cables.
The Tralucent box inside of a Pelican 1050 Micro Dry Case:
The gold-lined carbon fiber with black surround housing of the Ref. 1 looks amazing in person.  Depending on which angle you look at it in the light, gives off a sort of three-dimensional sheen.  The look is very lovely.  The Ref. 1's gold-lined carbon fiber goes very well with the dark gold copper-colored TWau cable that was provided as well.  The cable is just gorgeous regarding its presentation - subtle, yet undeniably beautiful once you take a second look. 
The Ref. 1's soundstage is wide.  I believe this partly has to do with the earphone housing and how the fit is deep, but does not go as deep or isolate as well as my Sensaphonics Custom Sleeves for the SE846, which have the look and feel of a silicone CIEM in comparison. 
The use of custom sleeves if the Ref. 1 ever partnered up with a 3rd party company would yield a more closed-in soundstage, more than likely.
From my first listen, the Ref. 1 sounds very colored, the mids and highs are just kind of blending in together and separating away from each other, pretty mixed regarding its presentation.  Reminds me of a rainbow, and a roller coaster - a U shaped presentation, with the highs and lows being accentuated the most.
The Ref. 1 sounds pretty clear, but colored clear.  However, there are clearer, more coherent sounding IEMs, which will be discussed in more detail later in the review.
From my very first listen, the Ref. 1 sounds artificial and does not sound in the slightest neutral.  Listening to it for a while, it sounds less artificial, but reveals its artificialness more if you have listened to more neutral IEMs such as the UERM.  However, if you like that type of colored sound, you may love it.
How I can best describe the sound of the Ref. 1 is that it sounds most like EQed 3D Surround Sound, and has a slight hollow sound, straight from the headphones – no source software EQ necessary for the effect.  
I feel that the Ref. 1 sound is the type of sound that can possibly grow on you.  At first it sounds very colored, definitely not neutral in its presentation.  Once you listen to it for a while, I can see why some people will absolutely adore its sound, and others will absolutely despise its sound.  What it does, it does very well.  It's kind of like with cars: you are probably aware that the Koenigsegg Agera R and the Bugatti Veyron are two of the fastest sports cars out there, but if you are more of a Rolls Royce type of person, you'll probably never like or prefer the Agera R or Bugatti Veyron, even though they are very capable in their own right.
I feel the treble goes pretty high, but not as high as IEMs such as the K10 and JH13 Pro that I’ve listened to.  The mids, in my opinion are the area that will and should get the most scrutiny.  You will love it, or you may not love it.  Simple as that.  The bass has weight and is lively in its presentation.
The Ref. 1 overall is definitely a love it, or dislike it kind of sound.
I have never heard an IEM quite like it, and that's a good thing, as a lot of IEMs have similar sound signatures. The Ref. 1 has its own very interesting and unique sound signature. 

The fit.  Oh my, the fit.  The fit is not horrible, but is not that great as well.  Thank goodness warrior1975 included a multitude of tips to use from various companies.  I stuck with the clear silicone smallest tips, as those were the tips closest to what I used with my SE846, which was the Westone STAR tip (silicone - small/green).  Since the earphone housing is not very large, it will fit inside more people’s ears easier than say the comparatively large 12-driver Roxanne (Universal IEM version).
Shure SE846 with Westone STAR tip on Left and Ref. 1 with Clear Silicone tip on Right:
Cable Issues
I have read that there were issues with the stock cable of the Ref. 1 coming loose, and that the current “official” workaround is to use glue to 'fix' the issue.  For the price of these IEMs ($1,650), I feel that particular fix is simply unacceptable.
The cable issue alone knocked off at least half a star regarding my overall score.
The stock cable (right side) is loose - if I so much as look the wrong way, the cable moves inside the housing just enough so there is a loss of sound - not an intermittent loss of sound, but a complete loss of sound. I have to push the cable in and wiggle it around so the sound comes alive again.  The stock cable is not fun to use at all and gives me so many issues with the lack of sound emitting from the right side if I do not stay perfectly still, and have to practically hold the right side of the cable and the earphone housing in a position where I can at least hear sound from the right earphone.  
Ref. 1 Stock Silver/Gold Cable:
Stock Cable is Very Loose Fitting on Right Side:
For these reasons, I scrapped the stock cable altogether and only use it when testing sonic differences with the SE846 and Ref. 1’s TWau cable.  As a result of having to scrap the Ref. 1’s stock cable, the Ref. 1 begs to be changed and/or upgraded with a cable that fits a little bit better than the stock cable (but not as solidly as most other manufacturer’s cables). This brings me to my impressions regarding the TWau cable.
The Ref. 1 with the TWau Cable
I feel the colored presentation the Ref. 1 with the Whiplash Audio TWau Reference Gold V3 (Silver) Balanced Cable (connected to TWau Balanced to SE Adapter) is somewhat tamed - still there, but not as prominent compared to the stock silver/gold cable.  Very similar, yet different sound signature compared to the stock cable.  The TWau cable smooths out the somewhat wild sound signature, accentuates the entire sound spectrum, and gives the Ref. 1 slightly more of an even keel soundstage to work with.  The imaging is more precise and the spaciousness and air of the treble is more apparent.  However, there is still a presence of the 3D Surround Sound effect and even sounds slightly hollow musically as well.  Even though the TWau cable does weigh more and is thicker than the stock cable, it is very comfortable, and the cables have not popped out of the earphone’s sockets yet, however I do get intermittent sound drops in sound as I am trying to re-adjust the earphone housings in my ears.  I also like the soft overmolding/memory cable, which is one of the most comfortable I've felt around my ears.  I am not going to subject the TWau cable to any strenuous tests like working out or running, but for walking around, you should not have any problems with the TWau cable. 
Whiplash Audio TWau Reference Gold V3 (Silver) Balanced Cable:
I compared the Ref. 1 to the Shure SE846, which should be easily accessible online and at certain airport InMotion Entertainment stores in the U.S., as I feel it is a great IEM to compare with so the most people can have a reference IEM to go by when reading about both sound signatures. The Ref. 1 and SE846 sound signatures are similar in some ways, and dissimilar in other ways. 

Power to Drive the Ref 1
Compared to the SE846 (which has ~9 Ohm of impedance), the 26.8 Ohm Ref. 1 takes 3-4 higher volume clicks from my iPhone 6 to reach the same volume as the SE846, for reference. 

How low can you go?  I do like the bass that emits from the Ref. 1 is nice and weighty.  It does not hit as hard or as low as the SE846, but is full-bodied, which is also nice as well.  I love bass, and the bass is definitely great on the Ref. 1.  It does not feel too loose, and is not tight/taut like the SE846's bass can be, especially with the HL Silver Litz cable.  Both the Ref. 1 and SE846 have great lows, as the SE846's bass goes lower, is slightly tighter and is very versatile with various bass notes, while the Ref. 1's bass is weighty, goes pretty low, and hits with more fullness and heft.  There is no winner in this regard, as both have their own sub-bass note signatures - the 'better' bass regarding both IEMs really comes down to your individual preference.  

The mids, overall I feel are better executed on the SE846, as it is not as colored, and is coherent regarding its presentation.  The Ref. 1's mids on the other hand are all over the place in my opinion. Some songs, the mids sounds pretty good, and others, not so much. 
Regarding the highs, the SE846 and Ref. 1. are very similar, as both extend well (as I am using modded blacks with my SE846, but the white filters act in a similar way, elevating the frequency response (FR) +2.5 dB 1kHz to 8kHz from the blue filters and +5 dB 1kHz to 8kHz from the stock black filters).  With the SE846, I can change my FR to what sounds great to me, so I can say that with the stock black filters, I would like the Ref. 1 more regarding the upper mids and highs, but when I listen to it with the modded black filters, the SE846 sounds better.
Shure SE846 Blue and White Filters (foam damper inside blue filter is shown):
Sound Signatures
If you are searching for a more coherent and changeable FR sound, the SE846 is right for you, in my honest opinion.
If you are searching for a more colored and possibly lively unique sound because of the colorness, the Ref. 1 may be right for you, if you make sure to demo the Ref. 1 and other top of the line IEMs first – before purchasing.

My Fiancée’s “Crude Assessment”™
An important comparison was performed as well.  My fiancée, who is not an audiophile, listened to the Ref. 1 with TWau cable and small clear tips, as well as my SE846 with HL Silver Litz cable and the Westone STAR (small/green) tips.  She spent a few minutes with each, and said, “I like yours better.”  I asked her, “Why, how come?” She replied, “Well, yours sounds more crisp.”  Afterwards, she called her comparative listening and findings a “crude assessment”, whereas I believe it is an honest assessment especially since she has never listened to any top of the line IEMs before (other than my SE846 with the stock SPC cable one other time briefly.)
Is the Ref. 1 Right for you?
If you are not a basshead, the Ref. 1 is not for you.  Another earphone for you may suffice, like the UERM, K10 (universal version) or the JH13 Pro - all C/IEMs that are not as bassy as the Ref. 1.
If you try out the Ref. 1 and love it, then that is great.  If you don't love it, that is okay as well.  I feel that for the price, the Ref. 1 is only worth it if you have listened to various C/IEMs and have come to the conclusion that the Ref. 1's sound signature is truly for you, no matter what. 
With that said, I feel that the better buy is the SE846, for several reasons.
1.  You can purchase the SE846 for less than 1K nowadays, just check online and make sure to either purchase from an authorized seller and/or you have the original receipt - the Ref. 1 was purchased for $1,650.
2.  You can change the sound signature (FR) +/- 2.5 dB 1kHz to 8kHz using the various filters - with the Ref. 1, you cannot.
3.  The fit can be cumbersome with the Ref. 1, from finding the correct sizes-fit-all tips for you, and currently not having any way to shell the Ref. 1 in a CIEM body or a custom sleeve.  I read that there was a user who purchased a Westone UM56 Custom Adapter for his Ref. 1, but he said the earphone housing juts out too much, and after looking at his pictures, they do jut out of the ears.  The Ref. 1 with UM56 Custom Adapter looks kind of like Frankenstein's neck screws, and may not look the most aesthetically pleasing to be of good use out in public.  The SE846 has a better fit.  Even with the sizes-fit-all tips, I wasn't able to get the most optimal fit and seal with the SE846, so upgrading to the Sensaphonics Custom Sleeves allowed me to have the most optimal fit, seal and deep isolation that every IEM owner should experience.  To have that option available for the SE846, and knowing that the Ref. 1 does not have any viable and close-to-CIEM options for creating the best fit and seal makes the SE846 the 'winner' regarding fit by a mile, and then some.
4.  Here is a human outer ear diagram (from to help with the names of parts of the ear:
Since I feel you cannot workout with the Ref.1 and the stock cable, let alone walk around without hearing sound drops, using the $525 upgrade cable (or at least a better fitting cable) is a must.  I am not sure how you will feel about running or doing any strenuous workouts with an over $2,200 pair of earphone + TWau cable combination, and knowing the overall seal around the tragus, insicura and/or cavum will introduce sweat in the ears, possibly into your ear canal because the Ref. 1 is not custom-fitted to your ears.  Comparatively, the Shure's SCS had the best fit, seal and isolation out of all of the earphone silicon/comply tips that I have ever used, period.  After running for 4 miles, no sweat went past the crus helix, tragus, incisura and/or cavum areas of the ear.  Meaning, no sweat made it into the ear canal.  As a result the SCS is a gym rat/fitness aficionado's dream come true.
Shure SE846 with SCS on Left and Ref. 1 with Clear Silicone tip on Right:
Shure SE846 with SCS - Universal to Custom fit:
Given the very wide price disparity of the two, I would definitely want to demo the Ref. 1 and the SE846, or any other bassy IEM such as the Roxanne (when the screw is turned +10 dB) before dropping that kind of money.  I would have no issues recommending the SE846 because it does cost a lot less, has a sound signature that is not too far off regarding the Ref. 1, as the Ref. 1 is very unique in its presentation, but the SE846 is ultimately more coherent, controlled and euphoric in its presentation.
If you appreciate bass and long for the visceral weightiness of the sub-bass, the Ref. 1 may be a viable option, but for the price, there are just as great sounding, or better sounding IEMs on the market such as the SE846 or Roxanne (turned +10 dB).  If you are searching for a more coherently sounding IEM, I would look towards the K10, JH13 Pro, JH16 Pro or even the UE18 Pro, as all of these IEMs admittedly have a better overall sounding presentation in my honest opinion.  Happy listening, everyone!
Fair enough. To be honest, you made me very interested in those 846, somehow I should demo them. I will ask my friends to see if one of them have it, maybe I can demo it for a few weeks.
Apart from the higher treble part, I have no doubt that 846 performs top notch. I shouldn't die before hearing that legendary bass I guess.
Thanks for the nice explanations mate, much appreciated.
@AmberOzL, No worries, just wanted to clarify everything and make my findings as honest and transparent as could be.
I am not sure if you live in the U.S., but if do, you may/should be able to demo the SE846 at an airport InMotion store as suggested in the review.  If you do not live in the U.S. or do not live near an InMotion store, then yes, asking your friends would a good bet, and you can keep it for a little while as well.  If you get to demo the SE846 from a friend, you'll be able to change filters as well and listen for extended periods of time to suit and fine-tune your personal sound signature preference.  Truth be told, you should try to demo as many IEMs as you can and choose the one you like the most and most fits within your budget as well.  
If you do try out the SE846, make sure to have as deep a fit and as tight a seal as you can to be able to really feel the bass!  
Good luck in your endeavor regarding finding an IEM that is best for you.

Very interesting review. As no FR graphs are available, I have to admit, I was pretty surprise to find out they are so colored despite their name; Ref I think comes from 'reference'...


Headphoneus Supremus
Pros: Big, Full Bass; Large Soundstage; Clear Treble; Very Good Instrument Separation
Cons: Bass Quality Isn't Quite Top-Tier;Treble Timbre is Off; Poor Ergonomics, Poor Quality Control
Thanks to Greed for a 10-day loan of his Ref 1 set, which I fully burnt-in and auditioned. This set had the uber cable.
Super Brief Review (it's all just what my ears heard, if you love your Ref 1 set, that's great, no need to defend it here):
-Real, air-moving bass sound thanks to the vented dual dynamic drivers. Bass is big, full and has great extension
-Clear treble. I didn't hear sibilance and the treble avoids a dark sound as well.
-Very good instrument separation
-Big soundstage
-I found the ref 1 to be less v-shaped in sound than the 1plus2
-Bass control is not top-tier at all. For some the amount of bass will be a problem as it's quite a lot.
-Treble timbre is off for an expensive iem, some instruments, voices don't quite sound right compared to other iem/ciems which sell for hundreds less
-Large, clumsy earpieces, not a good design at all
-Uber cable is very stiff and practically unusable in any other context than sitting at home in a chair not moving or reaching for anything.
-Serious quality control issues. Many, many people have had to send their set back for repair

going for a Mentor,NT6 or K10 CIEM would be a better option i guess. 
Yep, mirror my thoughts exactly.
Tralucent Audio: Ref 1.
The Ref 1 is the second major IEM release from Tralucent Audio. On first glance it appears to be the same hybrid design (dynamic driver + 2 balanced armatures working in unison) as their first offering, the 1plus2, but a quick listing of the features shows that to not be the case. Apart from relatively smaller tweaks, the major change in design comes from the replacement of the standard dynamic with an isobaric setup. A typical isobaric design consists of two drivers placed together in an enclosure. These drivers are positioned either front to front, back to front, or back to back within the larger enclosure.
When I heard this, I assumed it would make for interesting possibilities. I just didn't guess how different the sound would be.
Side Notes
  • Yes, there is driver flex on insertion. It's bothersome while it happens, but it's something that is only of concern when you see Tom Cruise's asymmetrical face.
  • The cable pin/earpiece situation is still unresolved. I would not personally advise you to leave your Ref 1 hanging around your neck. You may look down to find your neck accessory to be $1600 less valuable. Yes, Gavin has suggested a glue solution, but I don't feel it's adequate for an item as  pricey as this. I know things take time, but a couple of tweaks to the housing and cable design could solve the problem.
  • The driver flex belies the fact that this is still an open IEM. It has the isolation of a HD600 or HD800. Thes are not the IEMs you're looking for...if you want isolation.
The majority of critical listening will be done using the Fiio X5 connected to my computer as a DAC through to the Tralucent T1 as the amp via the X5's Line Out. The Ref 1 is equipped with the new straight connector Silver&Gold cable option, and I've dressed it with the Ortofon tips. This Ref 1 is a loaner set from a friend, so it has been run through its paces before it got to me. I'll assume it no longer needs to be broken in, even though I'm more or less agnostic about the whole burn in thing.
Test Tracks
Feist - Limit to your Love
Kendrick Lamar - Don't Kill My Vibe
Die Zauberflöte: II. Akt, 29. Auftritt. Duette Papageno, Weib: "Pa - Pa - Pa" (Rene Jacobs)
Silent Knight - Versailles
I listened to several more songs, but these had specific elements that I feels would test the Ref 1's capabilities.

There are two types of IEMs when it comes to sound. Those that immediately strike you with one or more tuning features, and those that sneak up on you with their technical prowess. The Ref 1 is definitely in the first group. 
The proverbial elephant in the room here is the bass. It is indeed elephant-like in size and weight. I was genuinely surprised by the quantity of the bass, and the sheer thickness of the sound.
I'm a huge fan of the 1plus2's bass. It's close to my golden ratio of mid-bass versus sub-bass. It's nimble. It's hard-hitting when necessary, but almost never obstructs anything. It's highly textured. It feels like pure unbridled teenage energy. The Ref 1's low end is almost none of these things. It's simply too much bass, IMO. I also feel like it loses a lot of texture in the process. As a result of the size there is also an issue with coloration in the lower mids, where the mid bass bleeds further up. To add some scale to things, the Ref 1 dwarfs the ASG-2.5 when it comes to bass quantity. The ASG-2.5 on the low bass settings is both tighter and lighter than the Ref 1 by quite a margin.
Up to the midrange, the Ref 1 manages to retain great presence despite the bass quantity. However, I notice something quite interesting about the upper mids. To my ears, the Ref 1 is highly boosted in the upper midrange, to the point where it introduces this strange tonality and some level of graininess. It is somewhat reminiscent of the very first version of the the    ASG-1. Just like boosted bass can warm the sound of an IEM, boosted upper mids can impart a radio-like tonality to the rest of the mids. This is the case with the Ref 1. It can be appealing in certain instances, but more often than not I find it off-putting, especially when going back and forth with an IEM that is not so boosted. I think it was tuned this way to balance out the quantity of the bass, but it appears to have had some side effects.
Treble wise, the Ref 1 is without fault. It is smooth, extended, and very life-like. Treble has never been an issue for the Tralucent family.
On to the positives 

The Ref 1 continues the Tralucent tradition of being extraordinarily spacious. It does not quite have the spatial prowess of the 1plus2 because of the sheer size of the bass, but it still is proficient in width and depth. Forward projection is not its strong suit though. 
The Ref 1 is also never short for detail. I can't use the superlatives like "hearing things I've never heard before" but details in the mids and highs certainly shine through.
All in all, I'm not sure what to think about the Ref 1. On some tracks, it's an experience. On others, it makes me raise my eyebrows and wonder what Gavin was thinking. Perhaps it was the result of the influence of the FitEar customs he has owned. It almost seems like the polar opposite of the 1plus2, which can be good or bad depending on your perspective. I'm among the people who thinks the 1plus2 only needed a few tweaks to flesh out the mids slightly. But I am only one data point in the scheme of things. As always, YMMV.

Great review mate:blush:.... Now I don't think these will be for me:grin:... Maybe the 1plus2:sweat_smile:
Can't un-see Tom Cruise's facial asymmetry!
Pros: Raises the bar in "technical excellence" with its peers through is interpretation of bass, speed, soundstage. Driver flex on right IEM.
Cons: Fit is still a little fiddly like it's older brother 1Plus2, price, stock cable comfort


Tralucent Audio is a name that's appeared on Head-Fi only since August 2012 but has quickly made a name for themselves with their ability to challenge other IEM makers when it released it's 1Plus2. I reviewed that IEM last year as a love/hate relationship as I felt it excelled every aspect of audio technicalities an enthusiast or an audiophile seeks sonically but overall, didn't sound musical to my ears. My expectations of the 1Plus2 was eventually managed when I bought the earphone again but with the Tralucent Uber cable on the 2nd round. In short it took a little while for the 1Plus2 to get a little loving from me.
Now onto 2014, Tralucent Audio has done it again with a new model, the Ref 1 and this has taken a much shorter period of time for me to fall in love with - and with its stock cable, even more so with the Uber coupled with it, and in my impressions I'll tell you why.
The Ref 1 (I believe is the first to Edit: As per @shotgunshane, it seems Audio Technica has done isobaric before the Ref 1) employ an interesting isobaric design for it's pair of 9.2mm dynamic drivers, coupled with a pair of balanced armatures - so this is a 3-way, 4 driver, hybrid & isobaric IEM. But it seems Tralucent Audio didn't just want to go for unique in design, it further challenged it's own older brother, the 1Plus2, in technical excellence and improved on it's musicality.


The Ref 1 in many ways are very much alike the (latter version of the) 1Plus2 but just smaller. The socket design, the stem design, faceplate, position of the port, etc. are so similar it's the two models are easily mistaken for each other. As such comfort for me on both the 1Plus2 and the Ref 1 are very similar maybe leaning towards the Ref 1 for a slightly more comfortable due to it's size.
When popped into my ears, they do angle outwards at the bottom whilst the top inwards towards my skull, and this is due to the angle & length of the stems & tips into my canal, whilst the cable at the top of the IEM pulls the upper part of the IEM closer to my ears. As such the seal it creates is a light seal, of which if I move a lot, the earphone can pop out easily. However if I'm sitting, everything sits in place naturally. I can create a better fit by tightening the neck sleeve on the cord.
Whilst on the topic of seals, the isolation is similar to the 1Plus2. Due to the light seal and the vented port, isolation is average for my fit.
Thanks to @burtomr, he did remind me that with the demo Ref 1 unit I had, there was a driver flex on the right IEM only. This sounds like a crackling sound when putting on IEM and if I were to push it. It didn't bother me much as once I had it on I was listening to it for it's SQ, however I can see how others could find it annoying for an expensive IEM to have such an issue.


Tralucent has basically done it again by making an earphone that’s technical perfection but tailored for a different taste. This earphone is all the detail demon that the 1Plus2 was yet further incorporates musicality into it - which was what I was seeking in the 1Plus2. It has more “body” than the sound of the 1Plus2 but still remains technical.
One of the first things I noticed about the Ref 1 is how fast it was. Music just sounded more positive, lively, and slick overall. Articulate sounds transition so quickly yet naturally - slick and speedy. This provided an overall very refreshing sound across the board for all genre I was listening to. I'd very much like to see the waterfall plot of this IEM but I suspect it to have rather short decays across its frequency response.
Tonally to my ears the Ref 1 further carries on from the 1Plus2s but with slight differences. As with the 1Plus2, the Ref 1's bass extends deep with a nicely controlled rumble, into a tight mid-bass region which to me contributes to the speedy response mentioned previously. The way the bass is rendered, is one of the most addictive - it sounds realistic, clear, & taut.
As for the midrange, this is where to me the Ref 1 differs a little from  the 1Plus2. Overall, it has a fuller midrange which renders vocals in full bloom. However slicing into a little more detail, my ears seem to notice little dip in the lower region of the midrange which I think gives the overall vast soundstage for the whole signature. It's therefore able to achieve 2 goals simultaneously - provide a huge soundstage presentation yet with the rest of the midrange having a full sound give vocals a rich and blossoming body.
The trebles are personally to me the most welcoming especially when I found the 1Plus2 to sound sibilant with certain recordings on the stock cable. The Ref 1 manages the sibilance without sacrificing the treble extension. Trebles maintain it's airiness, crispness, detail, and smoothness.
As mentioned before, the slight dip in the lower portion of the midrange seems to contribute to the Ref 1's overall soundstage. The soundstage can't be emphasised further - it'a huge and vast, just like it's older brother. It's even more so with the Uber cable plugged into the Ref 1. I'd dare say that the soundstage would sit between my (former) Signature DJ's and TH-900's and that's where I feel the Ref 1 starts to challenge some closed back headphones.

Ref 1 with different DAPs

These days there's quite a bit of questions on synergy of the earphone with various amps, DACs, and DAPs. I've tried the Ref 1 with the Cypherlabs Algorhythm Solo -dB/Duet combo, AK240, HM-901 and NW-ZX1 and I feel that it works well with most of those combos with maybe the only exception being the NW-ZX1 where it starts to be more track and genre fussy. The NW-ZX1 tends to have a somewhat more treble-focused sound and combined with the Ref 1, on certain tracks can start to sound sibilant for my tastes. On the other hand tracks that aren't treble focused, on the NW-ZX1 the trebles can sound crisp and airy.
However for multi-genre and multi-purpose, I personally prefer the Ref 1 out of the AK240 or CLAS -dB/Duet in my collection.

Closing Notes

Personally for me, I feel Tralucent Audio has excelled in this new IEM. It's not only got a very innovative design by incorporating drivers in an isobaric configuration coupled with BAs for an overall hybrid design but more importantly producing a sound that has maintained Tralucent's house signature - technical excellence. It gives a fast and slick signature with a highly addictive bass and yet maintains the technical excellence of its older brother, the 1Plus2. It's provided a sound that I've not heard in other makers which make the overall experience very refreshing.
Great review~ Just wonder how long did you take to burnt in the IEM before writing up the review?
@svyr, yes as like the 1Plus2 too. I didn't bother regurgitating whatever I had written about the 1Plus2 for the Ref1 as in terms of design/fit they were very similar.

@superachromat. I had these loaners since 7th May. I won't say I've used them exclusively but have been using them a lot. Maybe 150 hrs burn in by the time I wrote the review?
Very nice read, making me drool like a fool.....
