4. Operating Instructions
4.1 Wearing the IEMs
For optimal sound and comfort, wear the IEMs with the cable routed over your ear.
- Insert the earpiece into your ear canal, ensuring a snug fit.
- Loop the cable over the top of your ear, allowing it to rest comfortably behind your ear.
- Adjust the cable slider (if present) to secure the cable under your chin.

5. Maintenance
5.1 Cleaning the Earpieces and Eartips
Regular cleaning helps maintain hygiene and sound quality.
- Gently remove the eartips from the earpieces.

5.2 Cable Care
To prolong the life of your cable:
- Avoid sharp bends or excessive pulling on the cable.
- When disconnecting, always grasp the connector housing, not the cable itself.

5.3 Storage
When not in use, store your SIMGOT EW300 HBB IEMs in the protective carrying case to prevent damage from dust, moisture, and physical impact.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound or intermittent sound | Loose cable connection, incorrect audio source selection, low volume on device, dirty nozzle filter. | Ensure cable is securely connected to both IEMs and audio source. Check audio output settings on your device. Increase device volume. Clean nozzle filters. |
| Poor sound quality (e.g., lack of bass, muffled sound) | Improper eartip seal, incorrect nozzle installed, dirty nozzle filter. | Try different eartip sizes to achieve a proper seal. Ensure the chosen tuning nozzle is fully screwed in. Clean nozzle filters. |
| IEMs fall out of ears easily | Incorrect eartip size, improper wearing technique. | Experiment with different eartip sizes for a more secure fit. Ensure the cable is looped over your ear correctly. |
| Cable detaches easily | Connectors not fully seated, excessive force on cable. | Ensure 2-pin connectors are pushed in firmly. Avoid pulling on the cable. |
