NA5S (Universal)

The NA5S serves as a bridge between entry-level and professional audio models, inheriting the high-end acoustic DNA of the brand. Its high-rigidity titanium metal conduit design effectively reduces cavity noise and enhances sound purity, depth, and spatial dimensionality.

This results in a three-dimensional listening experience that excels among competitors, accurately reproducing spatial details in recordings. The lightweight, ergonomic universal mold and superior craftsmanship ensure a stable and comfortable fit, making it ideal for long recording sessions, vocal practices, or everyday use.

Core Structure: Advanced Driver Configuration

The NA5S incorporates five balanced armature drivers, emphasizing "full-frequency mastery" with enhanced targeted frequencies for cohesive sound. Two full range balanced armature drivers cover most of the audible spectrum, ensuring tonal balance and preventing fragmentation.

In addition, it features two Knowles high-frequency balanced armature drivers that enhance treble detail and clarity beyond 10 kHz, delivering a more transparent audio experience. A large balanced armature driver reinforces low frequencies, providing powerful and textured bass.

This design offers listeners robust lows, warm mids, and delicate highs, ensuring a layered and immersive musical experience.

Sound Performance: True-to-Life Fidelity

With a "neutral fidelity" tuning philosophy, the NA5S accurately reproduces original recordings without artificial enhancements. Low frequencies are well-balanced with depth and clarity, maintaining articulate lines across genres.

The mid-range provides natural imaging, conveying vocal nuances and accurately portraying instruments like guitars and pianos. High frequencies are extended and smooth, ensuring detail without harshness, making long listening sessions comfortable.

The NA5S excels in resolution and imaging, capturing subtle dynamics in performances. Whether for studio monitoring, mixing, or everyday enjoyment, it delivers stable acoustic feedback that closely mirrors the essence of the music.

Elevated Configuration: Titanium Metal Nozzle Technology

The NA5S bridges entry-level and professional models, embodying the brand's high-end acoustic DNA with its high-rigidity titanium metal nozzle design. This technology leverages titanium's low resonance to effectively reduce cavity noise, while the calibrated conduit length and aperture enhance sound purity and spatial dimensionality.

As a result, the NA5S offers a three-dimensional listening experience that excels in its class, accurately reproducing spatial details in recordings. Its lightweight, ergonomic universal mold and superior airtight craftsmanship ensure a stable and comfortable fit for long recording sessions, vocal practice, or daily use.

Unlocking Potential: Prelude II Earphone Cable

The Prelude II is an upgraded cable designed for the NA Professional S Series, tailored to meet audiophiles' demands for superior sound quality. Its core focus is on enhancing resolution, balance, and sonic purity, maximizing the earphones' potential.

Utilizing Litz Type 4S silver-plated 5N OFC copper conductors and a four-braided weaving technique with a standard 4.4mm balanced plug, the Prelude II effectively reduces signal interference. This setup retains rich dynamics while delivering a darker, purer sound.

In terms of performance, the Prelude II achieves a precise three-frequency balance, with solid low frequencies and transparent, exquisite highs. This combination offers an immersive listening experience with clear soundstage positioning and detailed musical nuances.

Dual-Material Custom Sound: NA5S Ear Tips

To enhance the NA5S's sound potential, it includes two exclusive ear tips with distinct materials. The Nostalgia Audio XWB ear tips optimize high frequencies for enhanced treble and detail, delivering a refined auditory experience. Conversely, the LSR ear tips, made from liquid silicone, provide balanced performance across all frequencies, offering a natural and comprehensive sound quality for an authentic listening experience.
