5. Operating Instructions
5.1 Tuning Switches
The CCA-Hydro features built-in professional-grade filters with four tuning switches, allowing you to adjust the sound signature according to your preferences. Each switch modifies specific frequency ranges:
- Switch 1 On: Bass increased by 1dB (Low frequency up to 1 level)
- Switch 1+2 On: Bass increased by 2dB (Low frequency up to 2 level)
- Switch 3 On: Mid & High frequency increased 1dB
- Switch 3+4 On: Mid & High frequency increased 2dB
- All Switches Off: Basic graph (flat response)
Use a small tool (e.g., a toothpick or the included tool if any) to carefully toggle the switches. Experiment with different combinations to find your preferred sound.

5.2 Microphone Button Control (if applicable)
If your cable includes a microphone, you can control various functions using the single button:
- Short press: Play/Pause music, Answer a call, Hang up a call.
- Long press: Decline a call.
- Press twice: Next song.
- Press 3 times: Last song.
Note: The SPC (Silver-plated cable) version may offer a microphone option, while the 784 core Silver/Blue mixed upgrade cable typically does not include a microphone.

5.3 Initial Burn-in
For optimal performance, it is recommended to 'burn-in' your headphones by playing music through them for approximately 30-50 hours. This process allows the drivers to settle and achieve their full acoustic potential.
6. Maintenance

- Wipe the earbuds and cable with a soft, dry cloth.
- Remove ear tips and clean them with mild soap and water if necessary. Ensure they are completely dry before reattaching.
- Periodically check the metal protective mesh and metal filter for any debris and gently clean them.
6.2 Storage
- Store your earphones in a clean, dry place when not in use.
- Avoid tangling the cable by coiling it neatly.
