Warranty & After-Sales Support

Our service philosophy is based on long-term cooperation. Support does not end when an order is completed; we continue assisting customers after delivery.

1. Scope of Support

Depending on the product, order, and issue, after-sales support may include:

• Product setup and operating guidance.
• Pairing, channel, frequency, battery, cable, and connection troubleshooting.
• Assistance identifying whether an issue relates to the microphone, receiver, accessory, external audio equipment, installation, or operating environment.
• Replacement part, repair, replacement product, or other resolution where approved.

2. Requesting Support

Contact liyuzhenlyz5996@gmail.com and provide the order reference, product model, serial number where available, description of the issue, and clear photos or videos.

We may request reasonable troubleshooting or testing before confirming the next step. This helps avoid unnecessary returns and supports faster resolution.

3. Product Condition and Proper Use

Support is intended for products used according to the supplied instructions and normal operating requirements. Coverage may not apply to issues caused by:

• Accidental impact, liquid, fire, excessive heat, corrosion, or unsuitable storage.
• Incorrect voltage, unsuitable power supply, incompatible accessories, or improper wiring.
• Unauthorized disassembly, repair, modification, firmware changes, or replacement parts.
• Improper installation, misuse, excessive wear, or operation outside the intended environment.
• Consumable items, batteries, cosmetic wear, or damage unrelated to a manufacturing issue.
• Wireless interference or frequency restrictions caused by the local environment or regional regulations.

4. Regional Frequency and Compatibility

Wireless audio products may operate within specific frequency ranges. Customers are responsible for confirming that the selected model is suitable and lawful for the destination and intended application. Please ask us to confirm available configurations before ordering if regional frequency compliance is important.

5. Commercial and Bulk Orders

After-sales terms for distribution, project, wholesale, or specially configured orders may be set out in the relevant quotation, invoice, or written agreement. Those confirmed commercial terms will apply to the extent permitted by law.

6. Shipping for Service

If a product needs to be returned for inspection or service, we will provide instructions after reviewing the request. Responsibility for shipping cost, customs charges, and risk depends on the cause of the issue and the agreed resolution.

7. No Unauthorized Returns

Products must not be sent back without written authorization. A return sent to an unconfirmed address may be delayed, refused, or lost.

8. Mandatory Rights

This policy does not limit rights that cannot be excluded under applicable law.
