Signature Acoustics C-12: The Elemental Underdog Woodies
 
 
Signature Acoustics' Foundation
 
 
Audiophiles love music, especially when played from high quality audio products that contain several different flavors. Flavors that audiophiles usually experience with audio equipment can be spicy, salty, sweet, or bland. Now, imagine tasting any of the mentioned flavors in your mouth. Would your tongue handle the spiciness of a jalapeno pepper? What about the irresistibly sweet cinnamon buns? Would table salt alone allure or dissuade you from experiencing a lone flavor? Regardless, each of the mentioned condiment/food caters to a specific audience. Several audio companies have been created by an audio enthusiast group to enrich the population’s lives. Audio Technica, AKG, Sony, Beyerdynamic, and other companies have succeeded in placing a smile on peoples’ faces. Yet, there are also underdog companies that deserve the popularity.
 
Enter Pristine Note, a market that was created by an Indian group of audio enthusiasts in 2010. Before the conception of Signature Acoustics, the audio enthusiasts created an audio store that sought to import notable brands like Audio Engine, Audio Technica, Fiio Amplifiers, Brainwavs, and Allesandro Heapdhones. On 2011, Pristine Note created and implemented their own brand called Signature Acoustics. Signature Acoustics’s intentions are to create their own audio products that caters to both Indian and international markets. Before Signature Acoustics could produce an audio product, they dedicated 18 months of research, experimentation, and testing to introduce their first audio in-ear monitor called “The Elements Series.” Due to Signature Acoustics’ dedication to the audio market, they produced a great budget in-ear monitor called the C-12. The C-12, based on reviews and other information, was considered a budget hero for the Indian market.

I have received this in-ear monitor not as an affiliate with the company, but as a semi-experienced consumer who will one day venture to high-end audio.
 
I will also be reviewing another element in-ear monitor called the O-16 metal in-ear monitors. These in-ears are the big brother to the wooden in-ears that focuses on producing a “natural sound signature and spacious soundstage” by using an 8mm voice coil and an open back mesh design.
 
Before anything, however, I will provide my personal background of the music I listen to.
 
My Personal Musical Background:
My preferred genres of music are j-pop, pop, rock, classic rock, and some jazz. While I may not present all genres of music, I will briefly mention the genres of music that I failed mentioning.
I listen to at least 50 percent volume on my devices. However, as all devices vary in terms of volume output, articulation in the vague term *50 percent* will be explained.
 
On a Samsung galaxy note 4, the 50 percent threshold is at least 6 buttons in, but I normally listen to 7-8 volume notches. The volume bar goes from a 50-70 percent threshold,  except that the decibels from the galaxy and the in-ear signature acoustics comes at about 60-75 db. However, I normally attempt to listen at 50 db.
 
 
 
Build Quality/Design/Microphonics
 
 

 

The packaging for the C-12 is the same as the O-16, which is what I
will be reviewing next
 


Packaging of the O-16 series
 
 
If I had to describe the build quality of the C-12 in-ears in one word, the word would be solid. The material used for the C-12’s housing is basically a two piece wood. To verify my assumption, I scrutinized the housing’s structure and found scant traces of glue that suggests an assembled wooden housing. In order to test the build quality of the C-12s, I squeezed the housings to ensure the quality control of the wooden housings. Then, I proceeded to place them in my ears to check for driver flex. Thankfully, there is no indication of driver flex present in the C-12s.
 
The housings should be able to endure the physical abuse from the average consumer.
 
The design of the in-ear monitors remind me of the average earplugs meant for a good night sleep. The grain texture on the wooden housings looks fabulous enough to wear the audio product as a fashion accessory. However, I would be wary about one particular thing about the C-12s. The microphonics are problematic.
 
Microphonics are average for this in-ear monitor, but when one wishes to traverse through the outskirts of a city or town, the cable of the in-ear will collide with your clothing and cause a slightly vexing noise. Of course, the microphonics can be remedied through the shirt clip that the C-12s come with.
 
The cable used for the C-12s may be a positive or negative aspect of the in-ear. When I handled the cable of the C-12s, I immediately recalled the re262’s sticky cable. The difference? It doesn’t smell out of box, and lacks the adhesive texture that the re262s contained. Instead, the cable felt slightly rough in comparison to the plastic cabling from brands like Audio Technica, Hifiman, JVC, or Ortofon. The shiny spots on the cable indicates the plastic appearance to the cable. Despite the odd feeling to the cable’s texture, with a shirt clip, the worries of the cable’s “raspyness” can be mitigated. The positive point of the cable would be my own alleged claim that the disentangling process of the in-ear becomes easier.
The connector for the headphone output is superb as it uses thick, durable plastic with a strain relief of its own.
 
Accessories
I find the accessories to be just slightly lacking in terms of earphone tips. However, the product does come with a pouch, filters, and a shirt clip to compensate for the lack of additional eartips!
2 Small Tips
2 Medium Tips
2 Large Tips
A shirt clip
Two filters
A leather pouch
 
 
Fit/Isolation/Sound Leakage
 
Fit can be rather finicky if you solely go by the tips you’ve been given. Of course I, being the wonderful man with celestial organization skills, had to rely on the included tips for the C-12s.
I had no fit problems with the medium sized tips. All I had to do was insert the in-ear monitors as I normally do, meaning that I grab the housing, push it in my ear, slightly twist it if I don’t feel the seal bubble, and release. The same applies to the small tips, but the large tips are a different story. If you use large tips, please be aware that finding a seal becomes a tedious task. I followed etymotic’s tutorial for in-ear insertion, but I still failed to achieve a good seal with the in ear monitors. The best way for my ear canal was to either switch to smaller tips, or to wiggle the in-ear until a decent seal has been created.
 
Sound leakage on this in-ear monitor is phenomenal, no one can listen to what I hear from 2 feet away. The closed design of the in-ear is helps it achieve a private listening space.
 
Drivability/Amp synergy (I only own two amps)
The in-ear monitor is easy to drive on a Samsung note 4. I had to rely on 30 percent of the phone’s volume, or 4 out of 12 ticks. I only need 22 percent volume on a PC. On a sony Xperia, you will find out sooner or later.
Will post more about the amp synergy later.
 
 
Sound Quality
 
Lows – The bass contains a powerful mid-bass with a slightly more relaxed subbass. The mid-bass and sub-bass quantities almost match as the mid-bass prevails with an extra +3db in comparison to the sub-bass quantity. The sub-bass roll off is present around 30hz or so, maybe even at 28hz. The quality is somewhat bloaty with the mid-bass while it slightly seeps into the mids. If the lower mids weren’t a bit enunciated, then the bass would have overtaken the lower mids section entirely. Fortunately, the mids are forwarded and full enough to only be somewhat smeared by the bass. The bass in a few songs had me dancing as I listened to Daft Punk’s Doin it right, Some video game music I heard from the psx/n64 era, and to most of the beatles albums. The bass is bolder, stronger, and definitely thicker than most of the in-ears in my collection. It has slightly more thickness than the kef m200, and if most of you know what the sounds of the kef in-ear are, then you may be in for a treat (or not).
 
Mids – The vocals are pretty dang buttery smooth while retaining some (light) detail. The veil is what prevents this in-ear from being better than great, but for the cost, I believe it IS great. This in-ear has a great capability of reproducing beautiful female vocals (while still retaining most of the awesomeness of males) despite this slight veil. I’m not stating that the earphone produces enough clarity to have me dancing to the rhythm, but it has the smoothest vocals and almost conveys the emotion of the singers themselves (would have been a bit more emotional if clarity were added). As I stated in the lows section, the lower mids have enough thickness to add great warmth to this in-ear, while still having at least a decent (borderline passable) amount of clarity for you to understand words, even though the vocals are uncomfortably lush at times. The uncomfortable feeling occurs on songs that came from 70s to 80s (rock, pop, etc. The beatles, Aerosmith, and even REM) where the upper mids to treble quality and clarity are necessary. Timbre on this in-ear is unheard of at this price point. It almost sounds similar to the thinksound on1s, but only fail to fully deliver the instrumental timbre due to the lack of clarity and air that other in-ears possess. Having said that, The j-pop I hear (my dearest from guilty gear), or from a song like aoi-shiori’s galleli is a wonder to behold. The vocals are almost liquefied thanks to warmth of the wooden housings (and tuning), but have enough clarity for me to enjoy my j-pop music collection. The females reel you in, while the males gently soothe your hectic day. The mids ooze a great load of intimacy while staying organic and accurate to an instrument's timbre. As I already said, the mids are great, but it could use just slightly more clarity.
 
Highs – Unfortunately, the highs are muted and mostly dull compared to the in-ears that I own.
The treble rolls off at 13khz (to my ears) and slowly starts to lack the sparkle that only the 9khz contains (it’s not that sparkly either, I can just barely hear the strength of the treble’s quality because of that veil). The bass bloat most likely caused the veil to occur, but regardless, the treble is great enough for the in-ear user to hear an expansive soundstage (surprisingly from these small in-ears). However, it isn’t outlandish enough to make you believe that these were full sized headphones.
 
Soundstage – Wider than the usual closed in-ear monitors (such as the ath-ckr9, ath-im02, ath-cks77 etc), but lacks the depth that other in ears contain (the sony xba-h3, ath-ckr9) and of course loses to the kef m200 and sony xba-h3 in width.
 
Imagery – It is not spectacular, but the imaging is slightly below average as instrument separation is decent while lacking the accuracy and precision in instrument placement.
 
Conclusion – This in-ear monitor may not exactly appeal to people who crave detail, clarity, or even accuracy in sound production. However, the main audience for this in-ear is for people who wish to have a fun, bold, and relaxing sound that will help the owner feel at ease with his/her music. While this in-ear monitor is currently competing against other Asian brands such as the Ostry kc06, havi b3, or even the ttpod te1, this in-ear monitor can actually do a good job in satisfying a particular audio lover. I would say that if one is yearning for relaxed highs, profuse bass levels, and somewhat forwarded mids, then look no further than the signature acoustics C-12.
