## Details & Specifications
The 7Hz G1 is an in-ear monitor designed as an all-round performer for both competitive gaming and immersive music listening. Anchoring the design is a newly developed 10 mm dynamic driver featuring a dual-magnetic, dual-cavity structure driven by high-flux N52 neodymium magnets. Its diaphragm is engineered with a Diamond-Like Carbon (DLC) coating, providing high rigidity and low mass to minimize harmonic distortion and maintain crisp transient response across rapid transients.

Acoustically tuned with multi-layered damping to closely trace the Harman target curve, the G1 provides balanced sub-bass extension, uncolored and articulate midrange reproduction, and smooth, fatigue-free upper treble. This cohesive response excels at conveying spatial pinna cues and footsteps in competitive gaming while rendering acoustic instruments and vocal harmonies naturally. The CNC-finished anodized aluminum shells are intentionally compact and low-profile, resting flush inside the concha to enable extended gaming sessions and comfortable side-sleeping.
