Setup
- Select Ear Tips: Choose the silicone ear tips that provide the best seal and comfort for your ears. A proper seal is crucial for optimal sound quality and bass response. Experiment with different sizes.
- Connect the Cable:
- Identify the left (L) and right (R) earpieces and cable connectors.
- Align the cable connectors with the sockets on the IEMs. The connectors are typically 0.75mm gold-plated.
- Gently push the cable connectors into the IEM sockets until they are secure. Do not force them.
- Insert IEMs:
- Insert the IEMs into your ear canals. The ergonomic design is intended to sit snugly and securely.
- Route the cable over your ear for a secure fit and to minimize microphonics (cable noise).
- Connect to Audio Source: Plug the 3.5mm jack of the cable into your audio device (e.g., smartphone, digital audio player, audio interface).

Operating Instructions
Once properly set up, the KZ AS24 Pro IEMs are ready for use. Ensure your audio source is at a low volume before playing any audio to prevent hearing damage.
Volume Control
Adjust the volume directly from your connected audio source. The AS24 Pro does not feature inline volume controls.
Tuning Switch Adjustment
The AS24 Pro features an 8-level tuning switch, allowing for customized sound adjustments. This electronic filter system provides precise control over different frequency bands. Use a small tool (e.g., a SIM ejector tool or a toothpick) to carefully adjust the switches located on the IEM body.
- Switch 1: Adjusts low frequency (1 level).
- Switch 1+2: Adjusts low frequency (2 levels).
- Switch 3: Reduces ultra-high frequency (1 level).
- Switch 3+4: Reduces ultra-high frequency (2 levels).
Experiment with different switch combinations to find your preferred sound signature. Refer to the frequency response graph for visual guidance on the effects of each switch setting.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your KZ AS24 Pro IEMs.
- Cleaning Ear Tips: Regularly remove and clean the silicone ear tips with a soft, damp cloth. Ensure they are completely dry before reattaching them to the IEMs.
- Cleaning IEM Body: Wipe the IEM body with a dry, soft cloth to remove any dust or earwax. Avoid using harsh chemicals or abrasive materials.
- Cable Care: The high-purity silver-plated cable is designed for durability. Avoid sharp bends, excessive pulling, or tangling. When storing, coil the cable loosely.
- Storage: Store your IEMs in a clean, dry place, preferably in a protective case, when not in use. This prevents dust accumulation and physical damage.
