Experience Sound in Its Purest Form
Introduce your customers to a new benchmark in personal audio. Our G1 Pro 1DD+3BA 4-Way Hybrid In-Ear Monitor pairs a cutting-edge 10mm Diamond-Like Carbon dynamic driver with a curated array of world-renowned Knowles and Sonion balanced armature drivers — a combination that has long been the choice of professional stage musicians, recording engineers, and the most discerning audiophiles globally.
This is not a compromise between bass and detail. It is both, fully realized.
Key Features
10mm DLC (Diamond-Like Carbon) Dynamic Driver — Bass & Sub-Bass The foundation of the G1 Pro’s sound is a 10mm driver coated with Diamond-Like Carbon — one of the hardest, lightest coating materials available for acoustic diaphragms. DLC’s extraordinary stiffness-to-mass ratio allows the diaphragm to move with exceptional speed and precision, delivering:
- Deep, textured sub-bass extension down to 20Hz
- Punchy, controlled mid-bass with natural warmth
- Vanishingly low harmonic distortion, even at high SPL
DLC diaphragms are engineered to behave as a near-perfect rigid piston across its entire operating bandwidth — producing bass that is both powerful and technically accurate.
2× Knowles ED-29689 Balanced Armature — Midrange Knowles Corporation is the global gold standard in balanced armature driver manufacturing, trusted by the world’s leading professional IEM brands. The dual ED-29689 configuration is specifically optimized for vocal and instrumental midrange reproduction, delivering:
- Exceptional vocal clarity, presence, and natural timbre
- Accurate reproduction of guitars, piano, strings, and woodwinds
- Low distortion and high sensitivity for effortless dynamic expression
Deploying two units in this band further extends the midrange output capability and ensures clean, undistorted performance even in demanding acoustic environments.
1× Sonion 23XX Balanced Armature — High Frequency Sonion, a Danish precision audio components manufacturer with over 80 years of heritage, is renowned among audiophile IEM builders for their high-frequency BA drivers’ extraordinary resolution and smooth, fatigue-free treble character. The Sonion 23XX delivers:
- Extended, airy treble reaching beyond 20kHz
- Exceptional detail retrieval — cymbal shimmer, room ambience, and harmonic overtones
- A refined, non-fatiguing top-end character that sets Sonion apart from generic alternatives
Precision 4-Way Passive Crossover Network All four drivers are managed by a hand-tuned passive crossover network, dividing the audio signal into four dedicated frequency bands:
| Band | Driver | Role |
| Sub-Bass / Bass | 10mm DLC Dynamic Driver | Impact, weight, warmth |
| Lower Midrange | 1× Knowles ED-29689 | Body, male vocals, lower harmonics |
| Upper Midrange | 1× Knowles ED-29689 | Presence, female vocals, upper harmonics |
| High Frequency | 1× Sonion 23XX | Air, sparkle, detail, extension |
This architecture eliminates crossover phase artifacts, maximizes driver efficiency, and produces a coherent, seamlessly integrated soundstage that is both technically impressive and emotionally engaging.
Premium Shell & Ergonomic Fit Precision CNC-machined shells available in medical-grade resin, aerospace aluminum alloy, or stainless steel. The anatomically contoured form factor provides a secure, fatigue-free seal for extended listening sessions. Available in both universal and custom-molded CIEM configurations.
Detachable Cable System Standard 2-Pin (0.78mm) or MMCX connectors for easy cable upgrades. Available terminations: 3.5mm Single-Ended, 2.5mm Balanced, 4.4mm Pentaconn.
