3. Setup
3.1 Attaching the Cable
- Identify the left (L) and right (R) earphone units and the corresponding connectors on the detachable cable. The cable uses a 0.78mm 2-pin connector.
- Align the pins on the cable with the receptacles on the earphone units. Ensure correct orientation to avoid damage.
- Gently push the cable connectors into the earphone units until they are securely seated. Do not force the connection.
3.2 Selecting Eartips
The EPZ G30 includes multiple sizes of silicone eartips (S/M/L). Proper eartip selection is crucial for comfort, sound isolation, and optimal audio performance.
- Experiment with different sizes to find the pair that creates a snug seal in your ear canal.

The EPZ G30 earphones are designed for an over-ear fit, which provides stability and reduces microphonics (cable noise).

6. Maintenance
- Cleaning: Regularly clean the eartips and earphone units with a soft, dry cloth. For eartips, you may use a mild soap solution and rinse thoroughly, ensuring they are completely dry before reattaching.
