1) Basic manual for earphones.

Please refer to the”User’s Manual“for a basic manual.


2) Handling of Resin Parts.

The black body casing is made from ABS resin material. This resin material is coated with black paint.

While the coating is applied and coated, using alcohol, thinner, or similar solvents for cleaning can cause the paint to peel off. Once it peels off, it cannot be repaired, so please be cautious.

Resin Care)
Care is simple and only requires dry wiping with a soft cloth. Special cleaners are not necessary.

3) About coloring brass and copper (care and precautions).

The coloring of brass and copper by Momentum Factory Orii is also a special coloring process that utilizes rust, like the blackening of stainless steel.

Wiping off with thinner, alcohol, or light-removing liquid will cause the color to fade. Never use them.

Care of brass and copper colored metals)
Brass and copper are coated, so it is sufficient to wipe them dry or wipe them with a small amount of oil (rust-preventive oil, olive oil, etc.).

4) Replacement Cable.

The cable is detachable via MMCX connectors, allowing you to use earphones with cables other than the supplied one. However, note that there are various types of MMCX connectors.

There are differences like a thicker center pin, longer pin, and slight variations in the MMCX shape. If you attach an MMCX cable that differs even slightly, the MMCX on the earphones can easily break, causing issues like interrupted sound or no sound due to poor contact.

Most earphone issues arise from using different MMCX types. Repairs like replacing the MMCX part are possible, but it might involve significant costs due to remaking the earphones. So, please exercise caution.

5) About fitting MIROAK-II.

The MIROAK-II earphones are designed to be worn with the cable looped over the ears. If the fit isn’t right, trying different ear tips suited for you might help. However, as the casing needs to touch the ears to dampen vibrations, if the ear tips cause the earphones to be suspended in the air, the sound might become weak.
