Industry-First Technology for Uncompromised Sonic Fidelity

PW Audio No.15 — A Cable Designed to Preserve the Truth in Sound

One of the most influential yet often overlooked elements in audio quality is resistance. Even minute internal resistance within a cable can subtly—but significantly—alter the sound signature of your IEMs or headphones. In fact, a difference as small as 1 ohm can shift bass impact or treble clarity noticeably.

PW Audio recognized that if the resistance ratio between positive and negative conductors is not 1:1, the resulting signal can take on entirely different sonic characteristics. Through proprietary research into this imbalance, PW Audio developed a groundbreaking concept:
ORT (Optimized Resistance Technology)—a precisely calculated "golden ratio" of resistance for superior sound transmission.

♦ ORT-Equipped “No.15” – A Cable Unlike Any Before

No.15 is the first cable to feature ORT, intentionally tuning the resistance difference between positive and negative conductors to control transmission speed and signal behavior. The result?

A uniquely silky and supple vocal presentation
Vast and immersive soundstage
Natural acoustic atmosphere
Exceptional resolution of micro-details

Rather than overemphasizing the midrange, No.15 achieves a harmoniously balanced reproduction across the entire frequency spectrum—preserving nuance, energy, and atmosphere with elegance.

♦ Ultra-Low Resistance, Ultra-High Purity

One of No.15’s standout qualities is its extremely low internal resistance. By combining ultra-pure copper conductors with the latest manufacturing techniques, the cable minimizes conduction loss, effectively eliminating unwanted resistance between your music player and IEMs.

Thanks to this synergy of:

High-purity materials
Low resistance
ORT engineering

No.15 faithfully transmits the energy, dynamics, and subtle textures of your original audio source. It unlocks the full performance of your IEMs, preserves dynamic range, maintains accurate frequency balance, and allows listeners to experience the emotion and storytelling of music more vividly than ever before.

♦ Premium Materials & Flexibility

Sheathed in a custom blend of PVC + FEP, the cable offers outstanding flexibility, resilience, and low microphonics, enhancing immersion during extended listening sessions.

The refined metallic purple hue adds a touch of understated luxury to its mature design.

♦ PW Audio Proprietary Plug Design

Fitted with PW Audio's original high-quality connectors, engineered for pristine audio transmission and long-term durability.

The laser-engraved aluminum alloy shells offer exceptional resistance to corrosion and scratches, while showcasing the brand’s signature aesthetic.

♦ Handcrafted Excellence

Every cable is hand-assembled by skilled artisans—a cable-meister’s touch in every unit.
Critical areas, such as the over-ear hook section, are reinforced with meticulous layering for enhanced durability and connection stability.
Connector components are carefully selected for maximum reliability.

♦ Accessories for Practical Use

Includes a custom-designed original zip pouch that allows storage with your IEMs attached, tailored for real-world user convenience and protection.
