Iron man iron triangle CKR9 limited edition evaluation in earplugs

In the two-unit earplugs, everyone thinks of double-action iron units, and occasionally there is a hybrid structure that wants moving coils + moving iron. It is even less to say that double-acting coils, and most of the researchers in this area are Japanese manufacturers. First, it is JVC, and then there is the iron triangle. The double-motion ring structure of the iron triangle is not as awkward as JVC, so the shape of the earplug does not need to be done too much. We have already evaluated a push-pull double action before. The flagship model of the earplugs is CKR10 (other than the CKR series, there are CKR9, CKR7, CKR5, CKR3, etc.). At the end of last year, the iron triangle new product launch conference brought a limited edition earplug, its prototype official CKR series The flagship CKR9, why the iron triangle does not choose CKR10 and choose CKR9 as a limited-manufacturing model. Perhaps we can guess a certain reason from the evaluation.

Iron triangle CKR9LTD appearance introduction

The new version of CKR9LTD packaging is actually not much different from the normal version, but the more significant one is that there are 2 small logos - a limited edition LOGO and HI-RES AUDIO LOGO. There may be many people who do not know HI-RES AUDIO The right to use the logo has been transferred to the Japanese Audio Association and is no longer exclusive to Sony, so many new Japanese headphones are now using this logo. (The definition of this HI-RES AUDIO English wiki has not been updated, but instead The Japanese version is only introduced)

The CKR9LTD limited edition earphones have chosen the same bright red color as the limited edition of the well-received new product ATH-MSR7 (users call: stranger wife), the theme line control adds a golden embellishment to the edge decoration, highlighting CKR9 The stainless steel shell material is very close to the style of Iron Man. The volume of the cavity is the same as that of the flagship CKR10. It also has a built-in dual 13mm moving coil unit. In addition, the impedance of CKR9LTD is only 12 ohms and the sensitivity is 110db/mw, which is quite easy. Driven earplugs.

There are not many changes on the CKR9LTD accessory, two pairs of replacement silicone sleeves plus a full-featured leather carrying case.

The appearance of CKR9LTD is based on the shape of CKR series. The circular two-phase push-pull unit is large in size, so the position of the ear handle is opposite to that of the general earphone, and the catheter is also inclined at 45 degrees for easy wearing in the ear.

The quality of the iron triangle CKR9LTD is very fine and the details are meticulous. The appearance of the Phnom Penh LOGO is very arrogant, and there is no burr in the treatment at the air hole.

The only pity is that CKR9LTD is a pure music earphone, and there is no mobile phone line control. Another small detail: there is plastic tube protection at the plug, this detail is still in place.
