At the end of 2013, the Iron Triangle officially launched a new series of IM series earphone products to the Chinese market. This series of products is positioned as a stage monitor earphone. Therefore, the iron triangle also adopted the shape design of the customized earphone for the first time. The large plastic material cavity The structure is very iconic, and at the same time, it has a great difference in style with its own earphone products. Bubble Network awarded the most anticipated earphones in 2013 to IM04. Today, the author will take you to study the current The more sought after flagship ATH-IM03.

If you have used the iron triangle earphone products in front of the monitor, I believe that I must be impressed with the materials and workmanship of the iron triangle. The Japanese control of the product details is indeed commendable, but today the ATH-IM03 is the overall shell. They are all made of brown transparent plastic, but the delicate workmanship still makes it have a strong texture, it seems to have a "advanced" feeling.
If you have not only used the headphones of the three irons in front of you, but also used the high-end models of its home, you must know that the iron triangle is very good at using wood, paint and various precious metals in the design of earphone products, especially the flagships. Model and limited edition, the Iron Triangle is trying to make it a work of art.
The IM03 we saw today is undoubtedly contrary to the previous experience of the Iron Triangle. The IM series of moving iron earplugs are made of plastic material on the outer casing, which has a great connection with its shape design. The iron triangle IM series headphones are all The shape of the "public model" for customizing the appearance of the earphones, that is, the shape of the earphones is to better fill the auricles of the person, thereby improving the tightness of the wearing and making the sound insulation better, and this makes the IM series The earplugs have to increase the cavity structure.

The moving iron products before the iron triangle are often described by enthusiasts as "enchanting", the sound line is thin, the high frequency is bright and smooth, the low frequency transient is good and the lack of dive momentum is an excellent choice for listening to the "floating" female voice. Listening to string music is also inspiring, but the music adapts to a narrow face, the male voice will become creamy, the rock will become crisp, the symphony is too elegant... It is a very partial existence. And the iron triangle IM03 moving iron headphones can be said to be an iron triangle In the previous tuning style, although the overall sound line is still somewhat thin, the overall sound tends to be "balanced", the tri-band is evenly distributed, and the overall sound is excellent, the female voice is full and supple, and the low frequency is flexible. Has a good sense of volume, and in the high frequency, it reduces the sense of elegance, smooth and still.

After using a lot of equipment with IM03, one of the shortcomings of IM03 is that the sound field scale is slightly tight, and the performance of the large-scale symphony is unsatisfactory. Because the amount of information is too large, there will be chaos and lack of layering. However, the combination of the iron triangle IM03 and the SONY ZX1 can be said to be really good. It is a better combination of the author's hands. The omnivorousness is high. A moving iron earphone has a good low-frequency performance, especially the SONY alcohol. After the sound technology, the low frequency is flexible, and the dive is given. Although the sound field is still small, the sound density and information volume are just right, full and round, especially in instrumental music.
Female voice: Tsai Chin's voice is smooth enough, slightly lacking some thickness; Faye Wong's voice occasionally has a tooth sound phenomenon, the whole is full; and in the Japanese style, the speed is high, the sound line is full of power, not elegant, very Good penetration.
Popular in Europe and America: Well, if you use this combination to listen to such a dynamic style, you will find that the original moving iron headphones can also create a low-frequency effect of such an atmosphere, the sound background is clean, the low frequency has tension, and the key is flexible. Every detail is unmistakable, and it’s not confusing. It’s also said by a senior enthusiast: "This is the nightclub restore!"
MALE SPEAKER: In terms of male voice, although IM03 is stronger than the previous moving iron earphone products of the Iron Triangle, relatively speaking, it is still less emotional. Listening to Han Lei’s songs is not a force, lacking the momentum of the momentum, but it is very It is suitable for listening to the gentle male voice of Yuji Koji, and moving warmth to a small heart.

Nowadays, when many consumers buy headphones, they often consider the problem of "good push is not good". This is actually the fact that the headphones are not easy to make a satisfactory sound. Therefore, in this test, the author uses professional music playback. In addition to the use of a variety of mobile phones, the Apple iPhone 4s as a sound source is stress-free. Of course, the iPhone 4s in the case of the IM03, the sound level can not be compared with the professional player, the sound The fullness will decrease, the resolution will decrease, and the overall amount of sound information will decrease.
