Night Oblivion - discussions

As I’ve been asked to pay money to dead-fi in order to post anything that I work for with free-of-charge, I decided to quit already half-dead website.

A member of discovery thread recommend me to migrate to here.

Hello everyone👋 Wow I recognize 90% of your names😆 This forum doesn’t feel away at all!


—About the company

—How we started

Butastur is a small hawk primarily from Northern China and is a migrating bird flying nations over nations, continent over continent. This is Night Oblivion’s fist international debut, and this little but mighty hawk will carry the sound that will guide you through the dead of night.

I started this project for a sole purpose as an audiophile.

Music has no borders, but earphones are now becoming expensive toys for the rich people of certain rich nations, where only 0.1% of the global population is capable of enjoying them.

Now, even with $20, you can have very good sounding IEMs. However, so-called TOTL grades are still kilobuck toys that starts from $1,000 USD.

My goal as an audiophile hoping for a sustainable wired audio enthusiasts community is to expand that 0.1% of global accessibility of expensive toys, by pushing the boundaries to outreach to audio enthusiasts of the rest of us, other than the millionaire or Quid Pro Quo reviewers.

Finest sound for the rest of us.

In order to materialize my dream, I’ve started this project which needed two essential fundamentals as a business project:

Primary Investor: A gifted and passionate craftsman with the same goal of “finest sound for the rest of us.”

Secondary Investor: A well-trusted business partner with a solid transaction platform and logistics.

Gifted Craftsman and Master tuner:
Night Oblivion, Jinny Tan, accepted this project and worked hard with me to build Butastur from the scratch, from basic CAD drawing to driver seletions, making prototypes, all the way up to making logo and faceplates.

Business Partner:

Here are some stories:

I had several platform business partners in mind, asked a few, and got rejected when I mentioned the “Finest Sound for the rest of us” concept. The project was halted for a while, we ended up in the design phase with proof of concept, the drawing paper was left on the table with half completed blueprint.

“Maybe I’m just a Don Quixote”

I almost gave up the project, since it wouldn’t be realized without sponsorship. Blueprint is just a blueprint.

I’d like to thank the big boss of Penon who kindly accepted the sponsorship of project Butastur, and happy to see Penon backing up the backbones.

—Project Butastur received metal of honor “Nuisance to Head-Fi sponsors”:ok_hand:

Again many of you may noticed, this project may have threatened one of head-fi premium sponsors who sells $$$$ expensive toys. Head-fi removed all information regarding this project including a dedicated thread and messages me following:

“Pay us money :yen: or shut up for project Butastur”

Very nice :+1:

—Project Butastur

So…here we come.

Project Butastur is about to hatch.

I can share some development backend stories later on, as making one ideal IEM, is not a simple , throwing FR and asking craftsman to “make it”.

There are millions of engineering and manufacturing decisions to be made, as well as costs and labors.

Fortunate or unfortunate, I’m currently working for a Japanese automaker, as a senior management member, so making goods —from designing a prototype and post SOP mass production handling control, purchasing/ marketing / cost management, financial planning and analysis— is what I do in real life. We’ve discussed from driver auditioning as each of them inherit different native characteristics to detail specs with varieties of options (type of shells, materials, finish, faceplate design, logo). And my former job was a publisher and game producer of a Japanese online gaming company. This type of publishing role on this project is a perfect fit to my real life expertise.

Only thing I lacked is artistic drawing, so we outsourced concept drawings of faceplate to a professional artist.

Yes, I tried AI-drawing but it never pulled the image that I looked for.

Motive1 : Butastur flying through the dead of night

Motive2: The mighty hawk claw

She came up with variety of mock ups after the initial kick-off meeting with concept walk through with a rough sketch of mine.

Below is the first shoot, way too photorealistic. I regret that I didn’t take my business chinese class at college too serious, when this showed up. The concept sharing failed.

Then, from my past job experience as a publisher of a Japanese online gaming, I draw a sketch with some Japanese manga technics (Ne-mu rough sketch drawing with notes) and requested her to complete the rest of the embodiment/ detailing of the rough sketch, finally, we got the concept art materialized.

A human, hand-written, and finally a beautiful design.

Making this into faceplate took another long way to here, but I’ll save it for later on.

Here is final pre-polished , pre-fit prototype of face plate.

We soon will have the re-aligned face plate to be furnished by 7/25.

[7/21 Edit] Jinny just shared me the polished version video👏
Here is the screenshot from that footage. Oh boy…Huawei’s Leica quad camera is better than apple’s… Even for video recording with zoomed in screencap, the resolution is amazingly detailed.

*Logo placement will be re-aligned.

—Project Concept


:arrow_forward:︎Minimalistic neutral sound, no artificial exaggeration, Instrumental oriented

:arrow_forward:︎transparent, resolving yet rich sounding vocals


:arrow_forward:︎Tunable switches for versatility

:arrow_forward:︎Full-BA with Sonion AcuPass bass woofer

:arrow_forward:︎Allergy-free, long term listening friendly shell finish

:arrow_forward:︎Gender-free & Smaller-ear friendly compact yet fully utilized internal space housing-size (please refer uploaded prototype video on my twitter)


:arrow_forward:︎Price of Med-fi, Performance of TOTL


:arrow_forward:︎Easy to drive by USB DAC dongle class


:arrow_forward:︎No overwhelming box/package, keep accessories with bare minimum, spend money for hardwares and drivers

Although I do have my dream package, but asking a big name artist “Mika Pikazo“ for package design is simply unrealistic and of course it will cost a price increase which I definitely couldn’t afford, all budgets went to hardware and drivers.

So just let my dream afloat , I’ll put Mika Pikazo’s art

Sorry! No Waifu on the box.

:arrow_forward:︎BRAS (Butastur Reactive Air-pressure System)

Butastur features an innovative ultra-low frequency control that prevents the bass from overpowering the higher frequencies. The ear is protected from damage by maintaining a balanced sound level of 110 dB. A stunning physical bass diving that delivers a thrilling sensation to the head is the result, without compromising the clarity of the vocals and instruments. The product also reduces the sibilance sound, which can be harsh and unpleasant to the ear. The best low-frequency dynamic sense is preserved by Butastur, making it an excellent choice for music lovers.

Too long?

Here are BRAS techs in a simple Engilsh

-Prevents resonance and protects against stimulation caused by high frequencies

-Serves to discharge certain frequencies, protecting ears from hearing damage

-Discharge High sound pressure and effectively protecting ears

-Ensure long term wearing comfort without pressure-build up

-Serves as natural air pressure reserve, and delivers natural lower mid and bass resonance

Sound Impression: Night Oblivion - discussions - #163 by AmericanSpirit_JP


While I’m fascinated to learn that a Butastur is a bird of prey, I can’t help read it as a “taster of…” well I’ll leave it there.

In all seriousness an interesting read. Good luck!


Impressive. You have a lot of applause from me and good luck with the project! :fire:


Great move Dead-Fi is a money sucking pay for review shit forum.

My comment over there will probably get removed as well LOL

American Spirit, cheers to you thanks for hard work and time you put into this project. Much appreciated :pray:

Feel free to make some coin on the next one efforts shouldn’t go unrewarded.


Welcome to HFGF and thank you for being so transparent, it all sounds very exciting it will be interesting to hear folks opinions on the set when it’s released :+1:

PS: Night Oblivion sounds like it should’ve featured in How to train your Dragon :smiley:


personally would call such a project Harpy! A majestic and powerful bird, in which there is a lot of mysticism and mysteries!

Thanks ! :laughing:

Thanks for the warm welcome!:laughing: I probably made one of dead-fi sponsors upset as this project will make many of their offering a thing of the past

Lovely birdy😍

Haha if the Butastur projects breaks even, we have some future plans , and Harpy is a good idea😄


Welcome to HFGF - looking forward to the IEM / was an interesting read for sure.


Welcome here also Americanspirit :blush:

Been a little here also, the sponsorships of Head-Fi is very apparent when you know about it.

My friend Antonio Gladiator Cables can not write about anything that regards cables, be it a diy thread or recommendations for others even if it’s not his cables. Every message get looked trough and many deleted from him.

Head-Fi demand cash or your fucked as a brand owner big or small.


I never thought I would see the day you’d come to HFGFs, welcome, @AmericanSpirit_JP. This community is a lot smaller but more tightly knit. This new project of yours looks very promising, I’ve been following it since you first announced it.

I wish you the best of luck!


^^^ I think this community is not small. It’s just that few people write, but many people read! :slightly_smiling_face:


Good luck @AmericanSpirit_JP and welcome to hfgf. Looking forward to hear the project one day!


I’m sort of shocked to learn how head-fi deals with these things. Can’t say I’m a fan…

Regardless, welcome to the pleasuredome (had listen to this now)!

After the homerun you made with the SR8, I’ll be keeping a qeen eye on this project, and wish you the best of luck!


Hi @AmericanSpirit_JP. Just signed up here for this thread. Always knew deadfi was venal when it came to sponsor stuff; when one door closes another opens, as they say. I’m really looking forward to this project. You are the first reviewer I look for when it comes to new gear. Still so happy with the SoundRhyme SR5!


I saw your thread disappear and found out why on another thread. Not surprised! Good luck with the venture :slight_smile:


Like i said on the other forum. This will be my next purchase :smiley:
