XTZ参加北京音响展：
展室：303A
展出器材：XTZ最新款耳塞 --- EarPhone-12
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
EarPhone-12 - 掀起耳机革命！
背景介绍
EarPhone-12是XTZ的首款耳机！显然，如你所愿，我们开发了新产品。开发这款产品并不仅仅是为了创造一款或许性价比还不错的好耳机，还想要掀起一场革命 – 某种可以表达我们对音乐和技术之热忱的载体。
在测试我们的另外一款革命性的产品MH-800DSP原型机的过程中，这个想法诞生了。高品质音响元件和Dirac最新的DSP软件的结合产生了令人吃惊的效果！
通过软件优化系统（尽管是在近场条件下），音质的提升幅度已经让人惊讶了！或许这就是我们当初在MH-800DSP系统基础上立即想到设计这样一款耳机的原因。
之前我们从未考虑过开发耳机，但是当我们听到这让人难以置信的改善时，我们知道我们必须设计耳机！
我们不得不承认开发耳机非常需要技巧，因为他们太小了！
这也是为什么需要通过一段时间的研究从而获得完美声音的原因之一。这是一个对成本敏感的项目，但是高度优化的硬件和先进的DIRAC DSP软件的结合后达到的效果如我们期望的一样！
EarPhone-12和其他的“传统”耳机工作原理一样：只需连接到音源，就可以工作了！
我们花了更多的时间和精力在对这些“微型音箱”的声学开发上！通过在仿真人头上研究耳机的频率响应，反复用最精密的仪器测试，我们渐渐的接近“完美声音”的目标。
不管怎样，我们都是人类，最终只有通过不断比较测试结果和比较耳朵的感受，才能达到最终的最佳效果！
我们发现，与音箱系统相比，耳机的“完美声音”需要遵循几个稍微不同的规则。
最后加上Dirac DSP声音优化技术，这令人印象深刻的平衡和无暇之声音只能被描述为令人惊讶、激动人心，不仅仅是因为在时域的完美校准。我们确信这款耳机不管在任何价格内都是最好的。
我们考虑过好一阵在新耳机上采用某种类似我们的音箱的空间校准方案。这或许看起来有点可笑（因为它根本没有空间），但是这不是全部真相。订购我们的EarPhone-12，你会发现它有3种不同尺寸的橡胶垫。试一试，你就能听出不同尺寸的橡胶垫对低音部分产生明显不同的影响，橡胶垫越大，你能听到的低音越足！用小一些的橡胶垫可以听到更中性的声音，如果想要感受更多低音，那就用大一些的橡胶垫。
我们也花了大功夫减少背景噪声的影响。我们获得了（由听音环境里的低声引起的）噪声层的非常高的衰减，这样声音变得更加干净、更具动态感。
戴起来舒适也是耳机的重点之一。避免线材轻易损坏，我们决定采用一根类似带子的耳机线，这样更加牢固。
我们还考虑到另外一个普遍的问题：当你正在听你喜欢的歌曲，电话突然响了，你得立即停止听歌。此时，你无需把耳机取下来放在手里，只要把他们像项链一样挂在脖子上就可以了！ XTZ EarPhone-12 的耳塞末端有内置磁铁，这样，当你不得不中断听音的时候，只需把他们的耳塞放在一起，然后戴在脖子上就可以了。这同样成功避免了常见的耳机线缠绕在一起的问题。
我们希望你不相信我们所说的，自己来试试！
Dirac 开发的XTZ播放器

---------------以下为英文介绍--------------------
Earphone-12: The revolution for your ear!
PRESENTATION
The EarPhone-12 is our first earphone ever! Obviously, as you could expect from XTZ, we
went for something new. The idea behind this project was not only to create a good earphone,maybe with an excellent price/quality ratio, but to build something revolutionary, something that expresses our passion for music and technology.
The idea came up during testing of the first prototypes of our equally revolutionary MH-
800 DSP system. The combination of top-quality audio components and Dirac’s latest DSP software simply lead to stunning results!
The increase of sound quality, optimizing the system with the software, even if in this case
in near-field conditions, was simply surprising! Probably this was the reason we immediately thought about earphones, based on the experiences with the MH-800 DSP system.
It had never been in our minds before to develop earphones, but when we heard that incredible improvement we knew we had to!
We have to admit that developing earphones can be quite tricky, as they are really small! This is one of the reasons it took some time to get the perfect sound! It was a cost-intensive project,
but the combination of this highly optimized hardware and the extremely sophisticated DIRAC DSP software works as well as we expected!
Basically the EarPhone-12 work as any other “classic” earphone: just connect them to any
source, they’ll do their job!
A lot of effort was put in the acoustical development of these “micro-speakers”! Studying the frequency response of our earphones in a “dummy head”, measuring again and again with the most precise equipment available, we slowly got closer to the goal of the “perfect sound”.
Nevertheless, as we are all human beings, in the end it was only the constant comparison of what was measured, and what was “experienced” by our ear, that lead us to the final result!
We found out that the “perfect sound” of an earphone has to follow slightly “different rules”
than a speaker system.
Applying finally the Dirac DSP sound optimization, the resulting, impressively balanced and flawless sound can be described only as stunning, breathtaking, not least due to the perfect correction in the time domain. We claim this is one of the best earphones at any price.
We thought for quite a while about adopting something similar to the Room-Tuning options of our speakers also to the new earphones! This might seem ridiculous (as there猀 no room at all..) but this is not the whole truth. Ordering our EarPhone-12 you’ll notice they come with three different sizes of rubber cushions! Try it out, and you’ll see (hear) that the bass-character changes sensibly due to the different cushions, the bigger the cushions the more bass you get! Use the smaller cushions for a more neutral sound, the bigger ones in case more bass is desired.
We also paid a lot of attention to efficiently reduce influence of background noise. We obtained a very high attenuation of the noise floor, caused by rumors in the listening ambience, which contributes to a much cleaner and dynamic sound.
Also wearing comfort has a high relevance, when it comes to earphones. To avoid damaging the cable we decided for a strip-shape cable, which benefits from a kind of “built-in” stiffness.
We also thought about a classical problem: You’re listening to your favorite song, phone rings, you have to stop listening. Instead of being forced to keep the earphone in your hand during the “break”, just use them as a kind of “necklace”! The XTZ EarPhone-12 come with built-in magnets on their backside, this way, when you have to interrupt listening, you can just “put them together”, and wear them around your neck. Also the classical cable tangle is avoided successfully this way!
Well, we hope you don’t believe in what we claim- and check it out!
XTZ Player by Dirac
For the iPhone/iPad/iPod touch
The XTZ player by Dirac for the EarPhone-12 are a state of the art DSP player app for iOS. With it you can listen on all your music in
your iTunes library with the added benefit of DSP correction of your EarPhone-12. This transforms the ear phone from good to
excellent. It does this by correcting the frequency and the impulse response in software.
The frequency response is a sum of the earphone and the ears character and presents a huge challenge to make the frequency
response linear. With Dirac DSP technology we can overcome this problem and get a perfect frequency response and accurate transients. This results in an improved timbre and more natural sound. The impulse response correction will add
clearer voices and better soundstage to your favorite music.
With XTZ Player by Dirac you will get:
- An improved soundstage
- Clearer voices
- A tighter and deeper bass reproduction
- Improved timbre
- Perfect Balanced Sound
