Born Out of Hobby of DIY earphones
634EARS was created by Musashi Saita from his hobby of making DIY earphones in pursuit of the sound he liked for his own enjoyment. He wanted to share the happiness he creates with other like-minded people as well, and hence the brand was born.
Musashi san named the brand after his own name - the number 634 is also pronounced as Musashi or Rokusanyon in Japanese. It is also known as Rokusanyon Ears.
Trivia: The tallest tower in Japan, the Sky Tree, has a height of 634 meters
One of the specialties of 634EARS earphones is that they are 100% made by hand - preparation of housings, tuning of driver, assembly - everything. Through repeated trial-and-error learnings are incorporated to achieve the desired result.
Dynamic Drivers for Music
All 634EARS iems are based on Single Dynamic Drivers only, with aim of creating sound more musical than analytical. Musashi san prefers dynamic drivers as he feel tuning them is the best part of making the earphones by himself. Repeated experiments and trial-and-error methods are followed to develop the method of tuning different types of sound.
Customised Design and Sound
The USP of 634EARS lies in the fact that the materials can be chosen from a pre-defined set of choices to create a sound that is most suitable for the buyer. A mostly common material is wood. There is a wide variety of woods to be chosen from for any model. They do not only provide aesthetic aspects, but also distinctly affect the sound characteristics as well. Different woods have different inherent properties, which directly changes subtle but audible aspects of sound. These effects cannot be anticipated, and rigorous testing by trial-and-error method is done to identify them. Currently wood is mostly used for the backplates, but earlier it was also used to design the housing itself.
There is also the option to select metal backplates - Stainless Steel, Brass, and Copper. They also have distinct effect on sound likewise. There are some quite visually pleasing different types of Brass and Copper options as well.
In some cases, the tuning of the driver is also altered slightly according to the choice of backplate to provide the most optimised sound.
For the current flagship model, LOAK, there are different choices of housings based on Titanium, Stainless Steel, Brass, etc. Several limited-edition variations of LOAK have also been released with unique housing combinations, the details of those are mostly found on their instagram page. For all variations the tunings are different as well for the most optimised sound.

How to order
The ordering process for models with pre-determined fixed tuning can be done from the Order section of the official website. However, buying a 634EARS iem is an interactive process based on the buyer's individual preferences, and hence the best way to order is to have a conversation with them via mail or via their official instagram page.
