I have received the ARIA as a part of the Vibro Labs ARIA Universal tour on Head-Fi that took part on August 2016. I have spent a week with the IEMs while maintaining ownership with the Shure SE846 and the Ultimate Ears Reference Monitors(UERM), using my own sources as reference.

Testing chain: PC/RWAK240(optical out/line out) > RSA Intruder/Mojo > IEMs. The music used are from various genres on Foobar2000 and streaming from Spotify Premium.



The Aria is Vibro Labs' premier IEM and flagship. Buyers can choose between various wood grains and can be had in universal or custom version with 3D printed shells. It is a quad armature design with an impedance of 15 ohms at 110db spl/mW and all handmade in Maine, USA.

Build and Accessories
 
ARIA
This loaner consisted of a very good Pelican 1010 case with a cleaning tool and a ton of comply IEM tips. Unfortunately, the stem of the Aria is a bit too big for me so putting it in with the smallest comply was a bit uncomfortable but I am able to get a good seal to go on with the review. As for design, the wooden faceplates look excellent in person and definitely one of the most unique styles in IEMs I’ve seen so far. The finish is very clean and smooth as well. On the other side with the vibro logo, there are some rough edges that you can see reflected on the inside but this may be because of the 3D printing that was done with it. Overall, I think accessories-wise, they are pretty generous.
 
SE846
The SE846 has an excellent build except for the stock cable going to crap after several months of use. The connectors are not exactly the best though some may prefer this over the typical 2-pin that the two IEMs have. It has a vast array of accessories like tips and filters, while supplying a cleaning cloth and pelican-style hardcase. Different countries may have packaging though, but most of the time I find that my accessories not really being used much. In terms of design, the drivers are neatly packaged through the see-through shell but there are known complaints about the drivers rusting or the plastic being foggy on the stem of the IEM. I’ve owned my 846s for almost 10 months now and I’ve been happy with them though I’ve never really compared the sound to other earphones.
 
UERM
I will skip the build entirely because it has been reshelled by InEarz before I received it. Source-wise I didn’t hear any hissing with the RSA Intruder or Mojo.



Sound Quality

ARIA
Source wise, I didn’t find any issues with matching and no hiss from any of my sources either. Bass on the Aria is a bit veiled, but no midrange bleed which is always a good thing. Bass extension is very clean while having adequate detail, balance on bass side is very good, I prefer this over the 846. In terms of midrange, there is a downward slope which can make a lot of instruments sound a little bit pushed back. EQ would perhaps fix this but as of using stock, it’s not good for midrange-centric genres. The treble has a slight hotness associated with it that’s almost sibilant but this can probably be associated with the midrange issue. Turning it down to actual listening volumes, treble is conclusively warm with sibilance. Using the Mojo, the issue is alleviated a slight bit but the issue can still be heard if you try to notice it. The only issue would I would find is that the slight sibilance is also amplified with this combo though not at unlistenable levels.
 
Recommended genres: Bass-centric genres, Hip Hop.

SE846
The 846 is extremely sensitive and it can hiss with a lot of different sources. Also, impedance matching is important because most sources affect how it sounds. Bass is well textured in which it has layers and detail with clean extension all throughout. There is no muddiness with it and soundstage is at a decent width. There is a slight discontinuity with the transition of the midrange and treble region which can make it a bit all over the place. The treble also has a slight peak which reminds me of the SE215’s in a less severe way but it can be something that can be overlooked. I say this in which it’s easy to blame the recording rather than it being an SE846 problem but switching songs, I can definitely hear the 846 doing this. I would also say that the 846 is similar to the LCD-X sound signature but both having different textures in bass. Treble and midrange are nothing to write home about but the IEM can be very forgiving. It’s an IEM you would use as a musical pair, doing well with v-shaped oriented genres without being extremely v-shaped. Overall, I think it is picky with sources but it is very fun and engaging.

Recommended genres: Top 40, Pop, EDM, Hip Hop.

UERM
The UERM has bass that’s reminiscent of the HD800 stock. It’s not overpowering yet there is enough of it to accommodate a believable performance in an acoustic setting. As for genres such as EDM, it’s a bit too bass-light. To visualize this, think of listening to EDM for an audience of 1. In terms of midrange and imaging, this is where the UERM truly shines. The UERM has enough air as an IEM and it is detail-oriented in which it’s like the HD800 in IEM form, without the extremely harsh treble issues with stock. I think the UERM can be a bit treble forward though I wouldn’t say that it’s as bright as an HD800 stock with let’s say, a schiit amplifier. My biggest criticism of the UERM is that it can sound thin at times (due to the forward treble), which leads it to be lacking in body that the 846 can give. To add to that, it can be revealing with bad recordings. One can also say it can be shouty at times which is one of my big criticisms for it. Going with this IEM though, you get very good detail retrieval that is ideal for midrange-centric genres.

Recommended genres: Acoustic, Classical, Jazz, Vocal-oriented genres.

Closing thoughts & addendum:

Personal preferences vary from person to person along with the genres that they listen to, so reviewers must try to be objective and detach themselves from these biases to give an unprejudiced review. This can be compensated by assessing a piece of gear with its characteristics while reproducing the same testing procedures for each sample. Some will prefer the ARIA, the SE846, or the UERM with fairly sound reasons. As the ARIA is the subject of this review, I think there is much potential to be had if the midrange was tuned more correctly as it was advertised when it was announced. I would say the Aria is ambitious, as it claims to be an all-around contender at a bargain price (“ARIA is a true flagship at entry level prices.”; verbatim from the website). While there is really no IEM that can do it all, I would disagree on the Aria being the heir to that be-all-end-all throne for now. At its price point, I feel like the asking price is a bit too high with other available options in the market like the ones from Noble, ’64 Audio, or even the Chinese IEM counterparts that are very hard to beat for the money. Nonetheless, I think the Aria has potential to be improved as giving proper tonality and sound signature balance would allow it to be more compatible with other genres to be rightfully lauded as a be-all-end-all IEM.

 
Design:
The DAP definitely has a solid build to it. Very good in terms of its weight which kind of reminds me of the FiiO X5 when I owned it but almost all touch screen. I like the build quality a lot and the screen is wonderfully spacious. It is a tad bit big to my liking but that is probably because I’m already used to the form factor of my own DAP. I personally am not a fan of the buttons as it is hard to distinguish what side I am pressing if I want to change the volume or change the song. It would have been ideal if FiiO had used another mechanism for the volume control or used different buttons altogether to avoid confusion. Even when I have the DAP right next to me, I can’t just grab it and change the song without having a second look to make sure I am not increasing the volume.

Interface:
I like how FiiO made the DAP have two different modes, Pure Music and Android mode. I enjoy the dedicated music app by itself though it also needs a little bit of getting used to in terms of navigation. This is because there are buttons that don’t have labels on them and I find them necessary especially for those who are more used to iOS. The UI is very responsive, I don’t see any lag on it at all and the freedom streaming apps is definitely very convenient as well. One thing I don’t like about the X7 is the on-screen volume change. Sometimes it does not respond properly where I drag my finger and it’s not doing anything. There are also times that it’s the android-style volume bar that shows when changing the volume. The drop down pane also disappears sometimes where it only shows what’s playing rather than being able to change settings on the fly. Perhaps these are polishings that FiiO will address in the next few firmwares.
 
Sound:
The X7 is quite a contender indeed. I am using my SE846 and it provides a close amount of clarity and detail when compared to RWAK240. The X7’s sound signature is very flat and a little bit lacking when it comes to dynamics. While there are details on the X7, I think it still lacks when compared side by side with the RWAK240. They are not too far apart though, on a price and feature standpoint the X7 easily wins out though the RWAK240 does offer more storage, optical and balanced out if that’s what one needs. The bass is excellent and hard hitting, mixed with a well-balanced midrange and treble. The treble is very smooth and it makes music sound engaging as it should be. I would say that it is a good match for the SE846 which I think is particular when it comes to it source.

Final thoughts:
The X7 is truly a flagship in its own right and it can definitely compete with the more expensive AK DAPs. While I do enjoy the sound from it, the dealbreaker for me would be the small storage of 32gb internal and the interface which can be remedied with future firmware updates. I wish that FiiO had made the button layout more ergonomic and I would’ve been happier with a smaller device. Optical out would also be nice. I look forward to the modules FiiO would be releasing for it as well. 

NOTE: At the time of the review, these were the preproduction Omnis. I have not heard the blackwood version but I am pleased to say that there is quite a good improvement in the post production of the cherrywood. The midrange bleed is not there anymore and while being on a warm side, the tonality is very thorough and smooth. Bass quality is top notch, as it did not have much of the subbassy boom and rumble I remembered from the preproduction model. 
 
Out of the meet where I have tried the new version, it was definitely one of my favorites. I hope the following review does not fully sway you from considering Zach's creation in any way. They were very very good and surprisingly very open sounding despite the semi-open design.
 
 

The Blackwood and Cherrywood side by side.
 

Overall view of what this review consisted of.
 
First of all, I’d like to thank Zach for supplying the Omni for this review.
 
Introduction
 
I’m quite pleased with the build, especially with how the wood cups feel. For this review, I am using the cowhide pads with the default headbands. The Cherrywood arrived several days earlier than the Omni Blackwood did so I spent more time with it but I felt like I did my best in evaluating these two headphones. In brief descriptions, I would say the Cherrywood is a well-executed v-shaped headphone while the Blackwood is more of a midrange-emphasized closed headphone with a slightly warm signature.
 
The accessories I received with the headphones are the multiple pads that I couldn’t compare because I had been busy with the things in my job, three possible choices of headbands, a single ended and balanced cable, and a waterproof hardcase. My criticism when it comes to the case is that it could’ve been a bit bigger and foam lined on the inner sides. I’m slightly worried about how the foam is
compressing the earpads on the drivers.
 

So many pads, so little time!
 



Audeze case comparison. The opening mechanisms are also very different with an edge to the Audeze. I think the Audeze is the better case if you don't mind the weight as the separate compartment allows you to add extra things like a small DAP, amp, DAC or cables.
 
Sound quality
 

 
For both headphones, an AdCom GDA700 R2R DAC and a Schiit Asgard 1 were used for the purpose of this review. The GDA700 has given me massive soundstage for any headphone I've tried with it and the Omni's were no exception which is why I can't fully comment on how different they are. Also, all the things I've heard from this review is purely subjective. Please take it with a cup of salt because who knows, I might be deaf. Hearing things that people don't hear and all.
 
Sound (Cherrywood)
 
Bass is similar to how closed headphones have bass and I think this is the beauty of the semi-open design. This closed sound is something I’d describe as having quite a good bit of subbass but unlike certain headphones, it does not neglect having the midbass punch entirely. The speed when it comes to the bass is nothing to scoff at while still being able to maintain an adequate amount of subass. It kind of reminds me of the Alpha Dogs which I enjoyed when I had.
 
The midrange kind of suffer a bit but this is expected with the sound signature. I would say it is a miss when it comes to classical music where the mids almost sound recessed with songs like Chopin’s Nocturne No. 2 or Hungarian Dance No. 5. The Omni is not terrible when it comes to guitar or piano but the bass emphasis can cause these to be overbearing. An example of how the Omni does this would be the guitar notes in Benjamin Francis Leftwich’s Atlas Hands.
 
When it comes to treble, I think the Omni shines. I think this headphone will be liked by many people because of how the treble is with the addition of the bass which I think is the most emphasized part of this headphone. The treble is characterized as is slightly forward but it does not give any harshness or sibilance. The bass still does overpower it but it’s not unlistenable. You notice it when the Omni intends you to.
 
I can definitely say that the Omni is good for Hip Hop, Top 40/Pop, EDM and Live Concert recordings. But it can be a bit overbearing when it comes to Folk/Indie Folk/Americana, some alternative rock, Classical, and the likes which mostly have emphasis on the midrange. Overall, I think it’s a fun headphone. I’d pick this over the Alpha Dogs although I don’t know how it fares with the Alpha Prime.
 

 
Sound (Blackwood)
 
As for the Blackwood Omni, they sound more like closed headphones with some noticeable amount of bass rumble in the lower registers (try Childish Gambino’s Heartbeat). The midbass is not substantial but it’s there, which you notice with songs like Walk the Moon’s Avalance where it can be too hard hitting when it comes to certain headphones. Personally this is not something I’m not super fond with especially since I’m used to how Audeze presents its bass so I lean towards the bass that the LCD-2 or the LCD-X gives. This bass does go well very well with Pop and Hip Hop though.

With the midrange midrange, it’s definitely more refined than the Cherrywood but it can get ruined with songs that have even only an adequate amount of bass guitar like Temper Trap’s Fader. Piano and guitar sounds are very well handled compared to the Cherrywood so it can work when it comes to Jazz or Indie Pop. Classical instruments are also articulated better as well. My test track for this London Philharmonic Orchestra’s iteration of the Hungarian Dance No. 5. This is probably the best part that I like about the Blackwood.
 
The treble can be said to be veiled compared to the Cherrywood and I found it slightly dark in certain instances. Breakbot’s Baby I’m Yours shows this veiled characteristic but I can’t say it’s completely unrealistic either; I feel like it’s the treble that closed headphones tend to have. Certain songs might not work well to the Blackwood Omni’s favor, like Sbtrkt’s Hold On which has continuous bass notes all throughout the song.
 

 
Brief comparison of the Omni’s with the LCD-X:
 
The LCD-X has a different kind of bass than either of the Omni’s and it can be said that it may be catering to a different audience entirely. The Omni’s strength and weakness lies in its bass and this is all thanks to the semi-closed design. It’s a matter of preference at this point though I would personally choose the LCD-X as the better all arounder when it comes to bass centric songs while the two Omni’s can be said as specialists. The Cherrywood for Hip Hop, Pop and the likes while the Blackwood can be for Classical, Acoustic, and Jazz. The midrange of the X is very clean and smooth and I prefer it over either of the Omni. When it comes to the Treble, my X has a peak in the 5k region which makes certain vocalists sound rolled off so YMMV since Audeze does have a notorious history of not having consistent products across the board. The Cherrywood is probably my favorite when it comes to the treble, since it doesn’t sound peaky like the X, or veiled like the Blackwood.
 
In conclusion, value is definitely found with either of the Omni’s especially when you compare them to headphones like the LCD-X. You do get advantages with the X but there are trade-offs in addition to the price. Both of these Omni’s still do not amount to the LCD-X’s price and you are getting perhaps more or less 75% of what the X can offer in terms of fidelity. Out of the two, I personally like the Cherrywood but the Blackwood caters to those who don’t enjoy their treble too forward with the bass being able to extend substantially deep.
 
Thanks for taking the time to read this review.
 
A few extra shots:
 

 

Intro: I have spent adequate amounts of time with the B1, mainly after working so it was something I used to relax. I have an AK100ii I compared it with with a JH13. The Cayin C5 is having a few problems right now so I felt that it was not best to test it at this time.
 

Packaging and Item finish

 



 



 

Upon opening the package, you get a charger, 3.5mm interconnect, paperwork and the device itself. The device itself has a solid weight on it but with the surprise of the plastic volume knob. Another issue with the volume knob might be accidentally turning it when it's in your pocket which can be a real issue. It has a good feel when you turn it but I feel like plastic is still not the best choice for it.

 

It has a similar form factor with the Cayin C5 and it fits pretty well with the AK100ii as shown below.

 

 



 



 




The lighting is nice and pleasant but can be a bit annoying if you use it at night The alignment of certain setups also determines if the lighted parts will show or not, in my case it was covered by the AK100ii.

 

 

Sound Quality

 



AK100ii+Cayin C5+JH13

 



The stack with a JDS labs mini interconnect.

 

The sound reminds me of the AK100ii amplifier with subtle differences. There is no hiss coming out of these headphones and no noises in the volume knob. Bass response did improve a bit with the JH13 giving more emphasis on the bass than it usually does with treble. The AK100ii on the other hand gives slightly more emphasis on the treble which can make the JH13 a bit too piercing in the ears. I've also noticed that instrument separation with the JH13 is slightly less compared to my typical setup. Mids are just as good as the AK100ii to my ears. I did not hear any difference with the Class A mode with my IEM but YMMV.

Conclusion/Thoughts on Value
I wanted to keep this short and sweet and as objective as I can. Comparing A and B and recording what I perceived. I have pondered upon what audience they were trying to target with this and I think it does very well with IEMs and portable headphones. Since I already own the Cayin C5, I won't be buying this but the build quality and sound quality itself makes me give it a double take. I remember disliking the E12 a while back because it felt too bright and thin and this wasn't like this at all. I think this is one of those things that would pair well with any transport with a sub-par amplifier assuming you are not burdened with its size. What I could think of would be a FiiO X1 or DX50 which I think would go well with this. Value-wise, it's a bit higher than the competition with the FiiO E12, FiiO E11K and the Cayin C5 but you are getting the Class A feature which you do not see in any of these units. Having owned the C5 and E12, I think the B1 can hold its place pretty well. It's rated at slightly less compared to the C5 and E12 @ 500mW@32 ohms compared to the competition at 800mW@32 ohms. The advantage of this is that the volume knob is not too "sensitive" as I use my JH13 with the C5 at 3'o-clock to get to listenable levels.
