634EARS: Impressions, Discussions, and Appreciations Thread

Feb 15, 2023 at 8:50 AM Post #16 of 1,009
If you can make a comparative study among the LOAK-T(CL), LOAK-BSB, and LOAK-S96, that would be enriching!
I will definitely do the comparisons later, the Loak-S96 is still burning in, even just now the stage suddenly became quite big and a bit holographic and a few cymbal strikes definitely hit beyond my headspace.

Great to see small bespoke companies like 634ears get a thread for discussion. I did look into them a while back but was somewhat daunted by the choice of woods/metals and didn't end up chatting about it with Musashi... The more insight shared here, the better for all of us :D. They look like a true labour of love!

I can see how most end up the same way. For me it was an opportunity as I know about tonewoods for owning and playing the guitar and other string instruments. Here's a good link for tonewoods http://tonewooddatasource.weebly.com/

Loak BSB is actually remake item, part of the trio that Musashi-san made from brass parts that he acquired back, he made 2 Loak BSB and a Loak SBS from those parts.

So the Loak BSB has brass nozzles and brass backplate with stainless steel body while the Loak SBS is made out of stainless steel nozzle and backplate with brass body.

All 3 have the same tuning as the Loak-TB, but because of the different parts, they sound different from Loak-TB.

The Loak-S96 is also sort of an experiment by Musashi-san, made out of front and back stainless steel darkening and stainless steel body.

He only made 4 of these and probably will not make anymore because according to him the backplate does not dye very well.

This is my latest acquisition. For now I can say it is a pretty balanced sound signature where by none of the frequencies stands out and probably the most layered sounding 634ears I have heard.

Can’t wait to read your impressions on both!

Features and details of LOAK-B(BW)​

Although it is a limited sale, the new product LOAK-B (BW) has some features that are slightly different from LOAK, so I will explain the characteristics and details of its sound.
1) Structure and configuration to make the most of the sound of brass
2) Difference between two types of wood and full brass
3) Patina technique
4) Embedding of MMCX part
5) Reason for limited sale
6) Summary

1) Structure and configuration to make the most of the sound of brass​

Brass is a very unique metal material. This time, in adopting the brass, we are devising ways to make use of its merits and compensate for its demerits.

《Closed type and fixed bass》​

LOAK originally allows you to adjust the strength and clarity of the bass through custom tuning. In addition, there are two types for the back, open and closed, but LOAK-B (BW) has only one type, which has a fixed bass in the front housing and a closed rear. This is to make the most of the weight and richness of the brass sound, and to reproduce a rich and deep mid-low range. The bass is a value of "4" in custom tuning, so it's a lot, but I think it's very easy to listen to even though it doesn't have the strength of a hard core like stainless steel.

《The structure inside the front housing and the difference in driver tuning》​

The front housing has a wider space than other LOAKs, and by making use of reverberations and reverberations, you can feel the spread of sound. As a result, the sound in the closed type stays close to the ear and narrows the space. It's not as spacious as the open type, but the space is wider than the LOAK-S and T closed types, and you can feel the difference in the direction in which the sound spreads outward.
And since the brass sound is soft and cohesive, the outline is not conspicuous and the detailed expression is a little vague. is possible. If the stainless steel or titanium LOAK were tuned in the same way, the sound would be too tight and distorted, or the pitch would rise and the midrange would attenuate. It is soft and coherent with its unique sound characteristics, and delicate expression is possible without emphasizing the outline.

《Smoothness》​

A filter that diffuses the sound is installed just before the driver in the front housing, but LOAK uses the finest filter with the least blockage to produce a fine, mild and smooth sound. The fineness of the particles is silky and liquid-like, and does not make you feel rough. It also produces a very mellow sound with few peaks and no harshness or sharpness.

2) Difference between wood and full brass​

There are two types of LOAK-B: LOAK-BW, which uses brass + brass + wood, and LOAK-B, which is all brass.
DSC03318-1024x639.jpg

In addition, LOAK-B uses a brass patina technique on the body to bring out the blue rust and give it a unique look.

《LOAK-BW》​

LOAK-BW is made of wood, but by choosing wood, you can control the specific gravity, and you can have a moderately light weight while maintaining the solid and thick sound of brass. However, for the wood part, it is recommended to select wood with a certain degree of specific gravity (heavy) in order to bring out the goodness of brass. Cocobolo is used for the wood in the photo, but despite the richness and weight of the brass, the earphones are well-balanced without being clumsy.

  • DSC03505-1024x684.jpg
  • DSC03503-1024x684.jpg

《LOAK-B》​

The sound is the heaviest because it is full brass. The characteristics of brass are fully displayed. It is a sound with a heavy and sexy atmosphere. In terms of sound balance, there is a difference in wood, but is this the one with the individuality? The use of the patina technique makes it even more individual. The rear has a flat gloss dovetail finish and a hammered finish. Tsuchime is used in brass jewelry and accessories, but it has a rough handmade feel and is rich in expression.

  • DSC03518-2-1024x684.jpg
  • DSC03301-1-1-1024x684.jpg

3) About patina technique​

The patina technique expresses the rust of brass and copper by controlling it. Even in Japan, there are traditional techniques in some areas. I learned it by myself, but I use various things such as rice bran, soy sauce, and vinegar to apply the rust treatment. The interesting thing is that every time you do it, the expression will be different, and the colors and patterns will change subtly. No two are the same like wood. This time, it will be covered with rust close to blue or green. A resin coating is applied to prevent rust from progressing.
Of course, we also have normal brass that is not patina even if it is full brass. The price will not change, so if you are interested, please fill in that when ordering.

  • DSC03536-1-1024x684.jpg

4) Embedding of MMCX part​

MMCX is embedded in resin as a different part from LOAK. Some people complained that the MMCX part of LOAK was a little unreliable, so we improved it (although there are no examples of LOAK where the MMCX is broken and damaged). It looks cool and seems to fit well. There is no particular difference in sound.
DSC03293-1-1024x685.jpg

5) Reason for limited sales​

The reason why we have limited sales this time is because we can no longer secure the housing and parts each time due to the recent rise in parts prices, shortages, rising shipping fees, and the depreciation of the yen.
Even if you purchase a large amount, economic activity will be restricted rapidly and the economy will be bad, and if you try to purchase only the necessary amount each time, the unit price will be considerably high. In fact, one of the projects that started last year was suspended for these reasons.
Therefore, in order to continue business, it is necessary to purchase and make the necessary minimum to some extent. For that reason, we have limited the number of LOAK-Bs to 15.
If there is a certain amount of demand (such as 10-15 pieces) after it is sold out, we may be able to make an additional 15 pieces, but in the current situation, such a number is not possible for a maniac small business like 634ears. It's hard to imagine that it will come out, and I think that it will actually be a limited sale of 15 pieces.
Perhaps if this situation continues in the future, we will only be able to take the same sales method, and the existing models may be discontinued when the stock is exhausted. We apologize for the inconvenience, but we appreciate your understanding.

6) Summary​

In various difficult circumstances, there are restrictions such as limited sales, but LOAK-B (BW) is a brass earphone that has been in great demand since the launch of LOAK. I struggled for a long time because I couldn't handle the disadvantages of the sound well, but I was able to complete it as a wonderful earphone.
Although it cannot be added to the standard lineup, it is finished as an elaborate earphone with a rarity value.
A little different from the crisp and clear sound of the LOAK-S and T, the sexy, lustrous and deep smooth sound lets you listen to music elegantly. Although the number is limited, we hope you will enjoy the sound and commitment.

These are so beautiful. This would be the one I would get I think. I love the sound of brass.

Edit: is this not available any longer?

It was a limited run of 15.

I did ask Musahi-san about this a while back, he said if there are 15 confirmed orders, he might consider doing another run.

I’d like a loak B or at least a TB/TC, maybe I’ll drop an email to have more info on both.

634ears LOAK-TS,TB,TC​

10mm dynamic driver x 1.
Front : Titanium.
Body : Stainless steel.
Rear (Back plate) : Stainless steel, Brass, Copper.

  • LOAK-TS (Back plate : Stainless steel)
  • LOAK-TB (Back plate : Brass)
  • LOAK-TC (Back plate : Copper)

The back of the LOAK-T enclosure is now made of metal (stainless steel, brass, or copper) instead of wood, and the driver tuning has been changed accordingly.
The new model has a thicker, more powerful sound with a bass and weight that was understated in previous LOAKs.

TS (Stainless steel)

This model uses stainless steel for the back of the rear enclosure.
The very hard and heavy stainless steel produces a strong sound with high contrast and edges. 
It is characterized by a tight, core bass and bright, sharp highs.

DSC05640-1024x684.jpg





TB (Brass)
This model uses brass for the rear portion of the rear enclosure.
There are three types of brass to choose from: NORMAL, GREEN, and ANTIQUE SILVER. 
It is milder than stainless steel, but features highly saturated and gorgeous high frequency and low frequency with a low center of gravity.

DSC05658-1024x684.jpg






TC (Copper)
This model uses copper for the rear portion of the rear enclosure. 
Copper can be selected from three types: BLUE, COPPER RED, and COPPER PINK. 
The tone is even milder and gentler than brass. It is the most audible sound among all LOAKs.

I’m interested to put in an order if we can collate 15 orders to make it worthwhile for Musahi-san :)

Following, very interested in these.

LOAK-TC (blue) ordered - I went for the bassier and most powerful sounding set within the line-up (according to the manufacturer Mr. M.S.)

By the way, big 🙏 to @Ace Bee for starting the thread and having brought the 634ears brand and wide product line-up to our knowledge.

I cannot forget and thank @Xinlisupreme and @Scuba Devils enough for their patience and good advice leading to my decision getting a pair of these beauties 💪.
