1. Hearing Safety

• Use the lowest volume that allows comfortable listening.
• Reduce volume and take breaks during extended sessions.
• Avoid sudden high-volume playback when connecting, switching sources, or testing a product.
• Stop use and seek appropriate professional advice if you experience pain, ringing, unusual pressure, dizziness, or a noticeable change in hearing.
• Follow volume warnings and hearing-safety features available on the connected device.

2. Awareness of Surroundings

Do not use headphones in a way that prevents awareness of traffic, alarms, instructions, machinery, or other hazards. Follow local laws concerning headphones while driving, cycling, operating equipment, crossing roads, or working in controlled environments.

Noise cancellation and closed-back designs can reduce awareness of surrounding sound even when no audio is playing.

3. Charging Safety

• Use the supplied cable or a compatible, undamaged cable and power source that meets the product instructions.
• Keep connectors dry and free of debris. Do not charge a wet product.
• Do not charge under bedding, inside a closed heat-trapping space, or near flammable material.
• Disconnect the product if it becomes unusually hot, emits an odor, changes shape, leaks, smokes, or shows battery swelling.
• Do not puncture, crush, bend, burn, short-circuit, or disassemble a battery.
• Do not leave the product in a hot vehicle, direct sun, freezing conditions, or another extreme environment.

4. Battery Care

Rechargeable batteries are consumable components and gradually lose capacity. For longer useful life, avoid frequent deep discharge, prolonged storage at an empty charge, and unnecessary exposure to high temperature. Charge the product periodically during long storage and follow the manual's storage guidance.

5. Water, Sweat, and Dust

Do not expose a product to liquid unless the model has an expressly stated resistance rating. A resistance rating does not mean the product is waterproof in every condition. Resistance can decrease with age, impact, seal wear, temperature change, salt water, soaps, chemicals, steam, and high-pressure water.

Dry the product and charging area completely before charging. Liquid damage outside the stated rating may not be covered by warranty.

6. Cleaning

• Turn off and disconnect the product before cleaning.
• Use a soft, dry or slightly damp lint-free cloth.
• Do not pour or spray liquid directly onto the product.
• Avoid solvents, bleach, abrasive cleaners, compressed air at close range, and sharp objects.
• Clean removable ear cushions or tips only as directed for that material and allow them to dry fully before reassembly.

7. Fit and Skin Contact

Adjust the headband and cushions to avoid excessive pressure. Keep contact surfaces clean and dry. Stop use if irritation, swelling, or discomfort develops. Materials, cosmetics, sweat, cleaning products, and prolonged friction can affect sensitive skin.

8. Children and Small Parts

Keep small parts, cables, packaging, and batteries away from young children and pets. Small components can create choking or ingestion hazards. Children should use personal audio under appropriate adult supervision and at responsible volume levels.

9. Wireless and Medical Environments

Wireless products emit radio-frequency energy within their operating specifications. Follow instructions in aircraft, hospitals, fuel areas, and locations where wireless devices are restricted. People using implanted or sensitive medical equipment should follow the equipment manufacturer's guidance and obtain professional advice where appropriate.

10. Cables and Connectors

Insert and remove connectors by holding the plug rather than pulling the cable. Do not use frayed, bent, overheated, corroded, or liquid-exposed accessories. Keep cables arranged to reduce trip, entanglement, and strangulation risk.

11. Storage and Transport

Store the product in a clean, dry place away from pressure, sharp objects, direct sunlight, high humidity, and extreme temperatures. Use a protective case where available. Do not place heavy objects on the headband, ear cups, cable, or controls.

12. Repair and Disposal

Do not attempt battery replacement or internal repair unless the documentation expressly describes a user-serviceable procedure and you are qualified to perform it safely. Damaged lithium-battery products require special handling.

Do not dispose of electronic products or batteries in fire or ordinary waste where separate collection is required. Use an appropriate electronics or battery recycling program available in your area.

13. Reporting a Safety Concern

Stop using a product that appears unsafe. Disconnect it from power when safe to do so, move it away from flammable material, and contact ronpu888@163.com with the order number, product name, description, photos, and video when available.
