When it comes to Japanese earphones, we have to mention the Iron Triangle, which is famous for its excellent female voice performance and excellent styling. In 2014, the Iron Triangle launched the ATH-IM series ear muff earphones, including the ATH-IM50 and ATH-IM70 two coaxial dual unit dynamic earphones. Today we have the ATH-IM70 of the Bank of China.

The Iron Triangle ATH-IM70 (hereinafter referred to as IM70) is designed with a white paper box, which is not very grand from the perspective of packaging, and has some English information printed on it.

The back of the package has become a Japanese introduction... but because it is a national bank, there are some Chinese anti-counterfeiting information posted on it. The structural anatomy of the IM70 is also on the back of the package. It uses a special coaxial dual unit dynamic coil design, which can keep the earplug in a relatively light cavity size.

The side of the package has turned into an English introduction (does the Iron Triangle play splitting...). It can be seen that the IM70 is equipped with an interchangeable cable design, an original Compli sponge cover, a silicone cover in three sizes, large, medium and small, and a headphone bag.

There is also a black paper box inside the outer package, which contains the earplug body and related accessories.

The accessories of the IM70 are very simple, including three pairs of silicone sleeves (there is a pair of medium silicone sleeves on the earplugs), a pair of Comply black sponge sleeves, a leather sleeve and a manual in Japanese+English.

By default, the IM70 uses a medium silicone sleeve with a detachable wire.

The IM70 is designed in a round ear style with bright red color. It has a fashionable shape. The brand logo on it is black with silver color.

IM70 has ear loop design at the ear loop, and the wire has certain shaping ability. There is also a rubber block at the end of the ear loop, which can let the wire hang naturally and improve the convenience of ear loop.

There are left and right marks on the back.

Because of the coaxial dual unit design, the IM70 is relatively thick in the cavity.

The sponge filter screen on the IM70 can be seen after taking out the silicone sleeve.

The IM70 is designed with replaceable cable, but it uses a special two pin plug, so it is not common with our common upgrade cable.

The wire splitter adopts the common glue design.

"L" type 3.5mm gold plated plug.

In terms of listening sense, since we have just received earplugs and haven't been cooking for a certain period of time, here we will simply share our listening sense, which is in the environment of Lebi L5+medium silicone sleeve. Different from the iron triangle earphones we often contact, the IM70 is actually a middle and lower earplug. The feeling of the first ear is that the low frequency is too large, but it lacks the necessary cohesion, which is a bit scattered. Intermediate frequency distance is moderate, and the feeling of encirclement is good. High frequency is slightly bright, but the extension and analysis are not very good. The voice is the advantage of IM70. Although it is different from the classic "female poison" dyeing style of the Iron Triangle, the voice performance of IM70 is still commendable. The voice of IM70 is close, and the dental sound is well controlled. It feels smooth without too much staining.

IM70 is matched with Lebi L5.

More listening feelings about IM70 will be introduced in the subsequent evaluation.
