Gently align the pins with the sockets and push firmly until they are securely connected. Do not force the connection to avoid damaging the pins or sockets.

2. Selecting and Installing Ear Tips

The package includes various sizes of liquid silicone ear tips. Experiment with different sizes to find the best fit for your ears. A proper seal is crucial for optimal sound quality, especially bass response, and comfort. To install, gently push the ear tip onto the nozzle of the IEM until it is securely seated.

3. Wearing the IEMs

Insert the IEMs into your ear canals, ensuring a snug and comfortable fit. The cable is designed to loop over your ear for added stability and to reduce microphonics (cable noise). Adjust the cable and IEMs until they feel secure and the sound is clear and full.

4. Connecting to an Audio Source

Plug the 3.5mm or 4.4mm jack of the cable into your audio source (e.g., smartphone, digital audio player, DAC, computer). Ensure the volume on your audio source is set to a low level before playing audio to prevent sudden loud sounds.

Operating Instructions

The Hidizs MP145 IEMs are passive audio devices, meaning they do not have built-in controls for volume or playback. All controls are managed directly from your connected audio source.

Volume Control: Adjust the volume using the controls on your smartphone, DAP, DAC, or computer. Start with a low volume and gradually increase it to a comfortable listening level.
Playback Control: Use your audio source to play, pause, skip tracks, or manage calls.
Optimal Listening: For the best audio experience, use high-quality audio files and a capable audio source. The MP145's high sensitivity makes it suitable for a wide range of devices, but a dedicated DAC or music player can further enhance the sound quality.

Maintenance

Cleaning the IEMs and Ear Tips

Regularly wipe the IEM earpieces with a soft, dry, lint-free cloth to remove dust and earwax.
Remove the ear tips and clean them with mild soap and water. Rinse thoroughly and allow them to dry completely before reattaching.
Use a small brush or cleaning tool to gently remove any earwax or debris from the IEM nozzles. Ensure no moisture enters the IEM body.

Cable Care

Avoid sharp bends or kinks in the cable, as this can damage the internal wires.
When disconnecting the cable from the IEMs or audio source, always grasp the connector housing, not the cable itself.
Store the cable neatly coiled to prevent tangling.

Storage

When not in use, store your Hidizs MP145 IEMs in the provided customized pouch to protect them from dust, scratches, and physical damage. Avoid exposing them to extreme temperatures or humidity.

Troubleshooting

Problem	Possible Cause	Solution
No sound from one or both earpieces.	Cable not securely connected. Audio source volume too low or muted. Incorrect audio output selected on device. Damaged cable or IEM.	Ensure 2-pin connectors are fully inserted into IEMs and the audio jack is fully inserted into the source. Increase volume on your audio source and check for mute settings. Verify your device's audio settings are routing sound to the correct output. Test with another cable or audio source if possible. Contact support if issue persists.
Distorted or poor sound quality.	Poor ear tip seal. Ear tips or nozzles are clogged with earwax/debris. Audio source quality is low. Cable or IEM damage.	Try different ear tip sizes to achieve a proper seal. Clean ear tips and IEM nozzles as described in the Maintenance section. Use high-quality audio files and a reliable audio source. Inspect cable and IEMs for visible damage.
IEMs feel uncomfortable or fall out easily.	Incorrect ear tip size. Improper insertion.	Experiment with all included ear tip sizes to find the most comfortable and secure fit. Ensure the IEMs are inserted correctly with the cable looped over the ear.
