Please refer to the”User’s Manual“for a basic manual.
2) About blackening stainless steel (care and precautions)
The black color of stainless steel is not paint, but a special staining process using an oxidized film called black rust.
Please note that the color will not peel off like paint, but scratches and other defects will cause the color to fade, exposing the silver stainless steel underneath.
This special blackening “Gen” will naturally fade slightly as it is used. It is like jeans where the color fades at the edges and worn areas.
Caution)
Wiping off with thinner, alcohol, or light-removing liquid will cause the color to fade. Never use them.
Care of blackening stainless steel)
Wipe it dry or wipe it with a small amount of oil (rust-preventive oil, olive oil, etc.).
As the black color dries, it will gradually turn gray or brownish, but wiping with a small amount of oil will restore the shiny black color. It is best to care for it by wiping it up a little with a small amount of oil and a soft cloth.
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. The coloring changes as the item is used, becoming slightly darker and lighter.
Caution)
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) About fitting 9iNE
The 9iNE is basically worn by hanging the cable over the ear.
Since the metal part is a straight shape with a one-piece construction, it may be difficult to wear for those whose ear shape differs greatly from left to right or whose ear indentations are too deep or too shallow.
It would be a good idea to change the ear tips, but since the case is designed to be in contact with the ear to some extent, the sound will be quite weak if the ear tips are used in a state where the earphones float in the air.
Please try to use ear tips with the same shaft thickness and length as the standard as much as possible.
