Hello, this is 0DiBi! Sorry for the late review, everyone! You've been waiting a long time.

Today's product is headphones. Beyerdynamic celebrates 100 years, so they released the DT770 PRO X LIMITED EDITION.

What a long name! The important thing is the 100th Anniversary!! Isn't this amazing? Beyerdynamic, the company, is celebrating its 100 years.

And it hasn't even gone public yet. It remains a family business. So why is it that the headphones they made for their 100th anniversary, the DT770 PRO X LIMITED EDITION?

They could make a more expensive product. Why this? I haven't seen any official reasons yet.

If I had to guess, I'd say I think it's the best-selling product in the history of Beyerdynamic.

It makes me think, how is the Beyerdynamic 100th anniversary model? Let's see what it might be.

What is Beyerdynamic, a 100-year-old company founded in 1924, like? Oh, I'm so excited.

Beyerdynamic finally made a video. This is Eugen Beyer, founder of Beyerdynamic in 1924.

DYNAMIC was added to the last name BEYER to create the name Beyerdynamic! And the world's first DYNAMIC headphones were made in 1937.

The amazing thing about these headphones is that the DYNAMIC structure that underlies the current headphones is the beginning of it all. Until recently, the DT48 was the model name.

It was produced for a long time. The performance must have been incredible at the time. And in 1939, we made the first studio DYNAMIC microphone.

And the first? Sealed, open, with one driver. And we also made headphones with a semi-open structure; maybe it was 1985 or something like that.

This was the first headphone to use diffused field targets, and there were quite a few products released. The thing I value most about the beyerdynamic brand is that it's still made in Germany.

Most music companies are moving to China, where labor is cheaper. It's been a while since we moved the factory.

Well, even to Vietnam, where it's cheaper now. Production has shifted again. Why did they move so much to cheaper places?

Technology is so much better now. It is very difficult to automate the production of earphones or headphones. The difficulty of automated production means that it takes a lot of people to produce these.

The cost of manufacturing goes up when they have a lot of labor. There has been a lot of automation, but it still requires a lot of human interaction.

That's why we have to go to China or Vietnam, where there are a lot of factories.

But I've been to a lot of real factories! I've seen a lot of workshops and working environments. Ah~~ It's really surprising to see.

There are so many crazy things going on. That's the thing~~~ Should I call it this mindset? A product of my own making!

They don't have this mindset. So when I design a product, even if I'm just building it, it's very important to design it so that there are no defects or problems.

And the production is done in Germany by local workers? Well, that would make it easier for the manager. But even the price doesn't make much difference.

It's amazing. Labor must be expensive. This thing has so much history~! Or because of the know-how, the DT770 PRO is sold for 200,000 won.

That's an amazing price. The DT770 PRO X LIMITED EDITION box is similar to the DT700. The Y logo is printed large and with a sticker on top.

Made in Germany is highlighted in orange! The sticker is connected all the way down. Monitoring and recording quality is good!

Specs are listed. Let's remove the self-sealing sticker. The box is a little tight to open, and the headphones are inside.

DT770 PRO X checking the headphones later. There's a pamphlet detailing the history of beyerdynamic. The history is listed by year.

And then there's the product documentation. It explains how to connect the cables and how to replace the ear pads. It even shows you how to replace the headband.

When I lift the box... Ah~~~ I'll look at the pouch later. Let's look at the cable first: Mini-XLR 3-pin terminal.

What's with all this wire? This is a 3-meter long cable. Is the soft pouch made of nylon? The inside looks like this.

Oh, it's the 100th anniversary, but this pouch is a little... Okay, let's take a look at the headphones.

Unsurprisingly, there is only one color: black. First, let's compare it with the DT770 PRO. Note that this is the BLACK EDITION, so the pad color is black.

The regular version is gray; only the pad color is different. This overall size doesn't seem to have changed. At first glance, a lot has changed.

The biggest change! The biggest change is that the cable is finally detachable! Starting with the housing, the logo is a little different.

The impedance markings are gone, and the injection finish here has changed. So the overall design of the DT770 PRO X is definitely looking good.

And here's the yoke, and the connecting piece has been circularized. This part that secures the headband has also changed a lot.

LIMITED EDITION is printed here, and the headband has changed. First, the headband features a logo. The headband sponge is about the same thickness.

This one is a little bit thinner in the center. Beyer says they made it more breathable. It could be airy. Some people have different shapes of their heads.

I think it's a very good shape. It was just flat before. Here's a comparison with the DT700 PRO X.

Quite a difference overall, isn't it? Only the detachable terminals here are the same. Cables can also be shared. The design is very different, and the housing size is different.

And this pad is different, and the headband is different. But if you press this pad, it feels sponge-like. Definitely, the DT700 PRO X is good.

It feels like memory foam. The DT770 PRO feels a little bit like a sponge. If that's the domestic list price, the DT700 PRO X is 399,000 KRW.

The DT770 PRO X LIMITED EDITION is 349,000 KRW, and the DT770 PRO is 299,000 KRW. There is some price difference.

This DT770 PRO X LIMITED EDITION is equipped with the housing of the DT770 PRO and the STELLA.45 driver from the DT700.

Previously, DT drivers were available in 32 ohm, 80 ohm, and 250 ohm options. There were three choices.

The STELLA.45 driver is fixed at 48 ohms. The driver has low impedance and good drive capabilities. It seems to have been validated in the DT900 and DT700.

Please refer to the video here to see how the drivers are different. But the sound of the DT770 PRO X is a little different this time around.

A lot different? A little different. I looked at the reviews from people who bought it first. A lot of people really noticed a slight difference.

You're still a 0DiBi member. And there's something I want to talk about first. Without putting on the Beyer headphones, A lot of people are worried that the treble will be harsh.

I want to tell you that you don't have to worry about that.

With this DT770 PRO X, I think that's been validated to some extent. I'll come back to this later. So, let's get the DT770 PRO X measurement data out.

You've waited too long, so let's get right to it. Okay, here's the graph with the DT770 PRO X Olive-Welti target.

Can you see the strong V-shape? Notice the high-pitched peak. This time it's the low data. The bass is up a little bit.

The treble is a little stronger too. The data doesn't really jump out at you, so I'll show you how it compares to traditional headphones.

Graph compared to the DT770 PRO. It's kind of strange because it's odd that a driver change doesn't make a big difference.

Only the treble is slightly different here. And here's a graph comparing it to the DT700 PRO X. It has the same driver as the DT700 PRO.

The pattern is a bit more distinct. The bass level is different. Treble level is also different. Now that's interesting.

This must be the same driver as the DT700 PRO X. Overall sound balance is similar to the DT770 PRO. Now let's look at the RAW data.

First of all, the bass to midrange is pretty much the same as the DT770 PRO. The treble is just a little bit higher.

Next, the DT770 PRO X has a different bass response. There's a big difference in the treble as well. This is not just the driver, but the headphone housing.

I think it's a result of tuning. First of all, the front damper is much different between the 700 and 770 models.

That's a curious result. This clearly indicates that the STELLA.45 driver is not the same; the material of the diaphragm is different from the DT driver.

Although the material of the diaphragm is different from the DT driver, it is clear that they are made with very similar characteristics.

So I think that's why we got this result. Since these have almost identical driver characteristics, it depends on the housing and the tuning.

The sound balance is determined by these factors. So the driver characteristics are pretty much the same, but the 5 to 7 kHz range is pronounced here.

You might think that the emphasis on the high notes is overwhelming, but I've heard it too. It feels like there's an emphasis on the high notes.

There is very little sense of distortion because of this emphasis. I feel like the treble sound is a little different; the highs sound a little shrill.

It feels different from my old DT770. There are quite a few people who bought it first, right? I haven't seen a single complaint from any of them about treble distortion.

Many people are worried that the 900 and 990 make treble distortions. I think this definitely puts your worries to rest.

The DT770 PRO X is higher, but no one said it causes treble distortion. However, the 900 or 990 has lower treble.

Well, but there are exceptions. Some people say that the DT990 PRO is also irritating to the ears. That's mostly for people who are sensitive to certain frequency ranges.

I think so. So before you buy it, don't worry about the high pitch. The bass is just holding it up, and it sounds pretty good.

The bass detail is good. In the beginning, I was very focused on the changed treble. You might not immediately notice if the bass is good.

The bass is really good if you listen carefully. And it's definitely better because of this sound characteristic: the location of sound sources.

A direction! Let's start with the sound staging. The DT770 Pro has already proven to be one of the best staging enclosures available.

I think that's where the treble comes in. The treble is a little bit higher, so the staging is a little bit wider.

The treble has gone up a lot, and it has definitely improved directionality compared to any other headphones I've ever tested.

I could hear the directions in Battlegrounds clearly. Direction detection is very good. So these are the headphones that can handle both music and gaming in one.

I'm thinking of those of you who bought it early; I want you to test it. Please leave a review. Seriously, this sound is ambisonic good.

And of course, if you have good stereophonic sound, it's also very effective for stereo. I thought it would be pretty good for immersive audio.

In the end, I think the reason the treble was raised is maybe because current technology is considering a lot of immersive audio.

That's what I think, and that's my conclusion. Yes, today is the 100th anniversary limited edition of Beyerdynamic.

We took a look at the DT770 PRO X LIMITED EDITION. We hope we've answered your questions! The treble seems unusually high by measurement, doesn't it?

But when you actually listen to it, it doesn't sound irritating. Isn't that already proven by the reviews? I didn't say anything about hitting high notes.

So saying that beyerdynamic makes the treble harsh is only true for very sensitive people. I think you don't need to worry about it.

I guess the reason the treble is elevated is that they are considering immersive audio for work and gaming. And that's my conclusion. So, if you enjoyed today's video, please subscribe and like it.
