4. Setup Instructions
4.1 Attaching the Cable
- Identify the left (L) and right (R) IEM units and cable connectors. The cable connectors are typically marked.
- Align the 2-pin connector on the cable with the corresponding receptacle on the IEM unit. Ensure the pins are correctly oriented.
- Gently push the connector straight into the IEM until it is securely seated. Do not force it.
- Repeat for the other IEM unit.
4.2 Selecting and Attaching Nozzles
The 7Hz Timeless II includes various tunable nozzles to customize the sound profile.

- Select your desired nozzle type (e.g., standard copper, stainless steel cone, copper cone).
- Gently screw the chosen nozzle onto the IEM unit by turning it clockwise until it is finger-tight. Avoid over-tightening.
4.3 Selecting and Attaching Ear Tips
Proper ear tip selection is crucial for comfort, sound isolation, and optimal audio performance.
- Choose an ear tip size that provides a snug, comfortable fit and creates a good seal in your ear canal. Experiment with different sizes and materials.
