NAOBI-Ultimate Earphone Re-Cable

The NAOBI-Ultimate earphone re-cable is a model that aims for the utmost in sound quality without sacrificing ease of handling.
NAOBI wire material was used for the wire material. For high sound quality processing, Ultimate grade sound tuning and high sound quality parts are used in combination.

All the know-how cultivated in the development of YATONO-Ultimate has been put into this product. New material BS sheet and new CNT sheet (carbon nanotube) are used.
Furthermore, it uses a newly developed ultra-high quality plug and cable slider for the Ultimate grade.
In addition, we have made our own tuning to match the NAOBI wire material.

Among our products, the reproducibility of microtonal sounds is one of the best in its class. The sound image is vividly portrayed with fine particles, and is brought to the forefront with a sense of power. It also has high resolution and is characterized by a balance between detailed depiction and a high sense of freshness.

In NAOBI-Ultimate, the final sound quality is determined by our high-end portable amplifiers.TSURANAGI(We developed our own ideal amplifier as a high-end environment necessary for cable development) as a reference amplifier and completed it by repeated careful listening tests and improvements.
 NAOBI-Ultimate is a cable that shows its power the higher the potential of the playback environment.
Furthermore, it is very easy to handle and use among Brise Audio cables.

Six types of connection terminals on the earphone side for optimal sound quality and feel in various usage environments.
For player (amplifier) side input, 4 types (4.4mm, 2.5mm, 3-pole 3.5mm, 4-pole 3.5mm) are available in L-shape and straight (8 types in total).
A total of 48 different options are available.
 ※BriseAudio Direct Store also accepts special length orders.Please feel free to contact us!

Ultimate series

 All are individually controlled by serial number and product ID card; the Ultimate grade is constantly improved after launch and is controlled by a Ref. number on the product ID card.  

The Ultimate Series offers a wide variety of options to flexibly accommodate a wide range of portable audio environments. The cables are made of very expensive parts and materials, and are entirely assembled by hand, a process that does not normally occur in cable production. For this reason, we have decided to make this product completely on a made-to-order basis.

However, this offer is only available to customers who have purchased new products.

BriseAudio's original wire material (NAOBI), which was completed after the development of wire materials that are easy to handle and advantageous to sound quality, is used.
The special copper base material, which is not only pure but also has a crystalline structure, is spun from about 200 strands as well as YATONO wire that is more than two classes thicker, and these strands are then effectively braided together. These wires are effectively braided together.
 This is the new generation of BriseAudio's wire material, which is very easy to handle and offers excellent sound quality.

【Uncompromising parts developed exclusively for Ultimate grade】
The parts newly adopted for the Ultimate grade have been developed with additional know-how gained and further time and cost invested without compromise. We are not only concerned with sound quality, but also with quality and perfection.

Uncompromising parts developed exclusively for Ultimate grade

The parts newly adopted for the Ultimate grade have been developed with additional know-how gained and further time and cost invested without compromise. The result is not only in terms of sound quality, but also in terms of the extremely high quality of the finished product.

The cable slider used for the Ultimate grade is machined from OFC and finished with 24k gold coating.This is also effective in terms of sound quality, and we have made adjustments by comparing various materials, shapes, surface finishes, and so on. This is also a part of the finishing process.

For the shape-retaining wire for the earpiece, we have adopted titanium wire, which is specially treated after evaluating the sound quality and selecting the right material.Titanium wire, which is specially treated after evaluating and selecting materials for sound quality, has been adopted. This enables us to support both the handling around the ear and the sound quality.

The tip is bent to prevent ejection & for safety measures.

 Various types of connectors including original high sound quality connectors (MMCX, 2PIN, A2DC, PentaconnEar, IPX, MMCX for Sennheiser) are used (Please inquire for other types of terminals).)
Original terminals (MMCX, CIEM2pin, A2DC, PentacconEar (using OFC axis made by Nihon Dix), IPX, MMCX for Sennheiser) were newly developed for Ultimate grade.
All of these connectors use machined OFC shells. After a long period of development, we have created connectors with a very high level of sound quality and finish. We also have connectors for FitEar (pins are genuine FitEar), IER-Z1R, and others.

OFC (oxygen-free copper) high sound quality original L-shaped plugs (5-pole 4.4mm, 4-pole 2.5mm, 4-pole 3.5mm, 3-pole 3.5mm), all 8 types (L-type straight type) are used

NAOBI-Ultimate uses all (4.4mm, 2.5mm, 3-pole 3.5mm, 4-pole 3.5mm) PentaconnOFC plugs (our custom-specified axis) manufactured by Nippon Dics.
In addition, the shell (outer case part) is made of machined OFC.
The plug has a very luxurious feel and high quality finish, and you can hear a big advantage in sound quality compared to the average plugs on the market.
Both L-shape and straight shells are available, so you can choose the one that best suits your environment.
In addition, new materials have been added inside the plug and in the vicinity of the plug, and significant improvements have been made, including shielding and vibration damping.
