No. 15

A Cable Employing Industry-First Technology to Reproduce Faithful Sound

One of the factors that greatly influences sound quality is "resistance." Even slight resistance within a cable can subtly but certainly affect the sound of earphones and headphones. It's not uncommon for a difference of just 1Ω to change the bass perception or treble balance of earphones. PW Audio noticed that when the resistance of the positive and negative poles in transmission is not 1:1, the sound exhibits completely different characteristics. By independently researching this ratio, they developed ORT (Optimized Resistance Technology), which calculates the optimal golden ratio.

♦"No.15" is the first to adopt ORT, which brings unique characteristics to sound quality by differentiating transmission speeds and optimally adjusting the electrical resistance difference between the positive and negative poles. It offers unprecedentedly smooth and supple vocals, a vast soundstage, a natural acoustic environment, and subtle details. It achieves balanced reproduction across all frequency ranges, not just focusing on the mid-range, and capturing even the finest nuances.

Furthermore, one of the greatest features of "No.15" is its extremely low resistance. By using high-purity materials and the latest manufacturing techniques for the internal conductors, the design minimizes conduction loss, eliminating unnecessary resistance between the music player's internal resistance and the earphones. Through high-purity materials, ultra-low resistance, and ORT, it faithfully conveys the energy and nuances of the original sound source, maximizing the inherent performance of the earphones, suppressing dynamic range loss and frequency balance disruption, and allowing you to experience the performer's emotions and the narrative of the music more deeply.

♦It adopts an original PVC+FEP sheath that combines flexibility and durability.
It is easy to handle and suppresses touch noise, enhancing the immersion of listening.The understated yet impactful metallic purple color scheme embodies sophisticated beauty.

♦PW Audio Original Plug: The company's original plug is used, providing high-quality audio transmission and high durability. The original aluminum alloy cover, laser-engraved with the logo, boasts high corrosion and scratch resistance.

♦Handmade Supremacy with Attention to Detail
The connector parts use highly reliable components selected by PWAudio. The ear hooks are multi-treated without gaps to reduce connection instability and the risk of disconnection. Each cable is carefully finished by a cable master.

♦Comes with an original zippered pouch that allows storage with earphones attached. A highly practical design that considers the user's environment.
