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.
