Shenzhen Kensing Electronic Co., Ltd. ("Kensing") supplies business headsets on a wholesale/OEM basis. This policy explains how quality issues, samples and bulk orders are handled. Exact terms for each order are confirmed in the Proforma Invoice (PI) signed before production.

1. Samples

• Sample orders (1–5 pcs) are available for quality checking before bulk purchase.
• Sample fees and shipping are quoted on WhatsApp; sample fees may be credited against a subsequent bulk order, as agreed in writing.
• Samples are provided for evaluation and are generally non-refundable unless the product is defective on arrival.

2. Quality Inspection Before Shipment

• Every bulk order passes 100% finished-product inspection under our ISO 9001 quality system before packing.
• You may arrange third-party inspection (e.g. SGS, Intertek, Bureau Veritas) before shipment — welcomed and supported.

3. Returns for Defective Products

• Report any defect within 30 days of receipt with photos/videos and order number via WhatsApp or email.
• For confirmed manufacturing defects, we will provide one of: free replacement parts, replacement units in the next shipment, or a partial refund proportional to the affected quantity.
• Minor cosmetic variations that do not affect function (e.g. slight color shade differences) are not considered defects.

4. Warranty

• Standard warranty period is confirmed in the Proforma Invoice for each model (typically 12 months from shipment).
• Warranty covers manufacturing defects under normal use; it does not cover misuse, unauthorized repair, water damage or normal wear parts such as ear cushions unless defective on arrival.
• Replaceable spare parts (ear cushions, boom arms, dongles) can be ordered separately.

5. Order Cancellation

• Orders may be cancelled free of charge before mass production starts.
• After production begins, cancellation may incur costs covering materials and completed work already incurred.
• Customized/OEM orders (custom logo, packaging, firmware) cannot be cancelled once sample approval is confirmed.

6. Shipping & Customs

• Shipping terms (express, air, sea; EXW/FOB/CIF/DAP) are confirmed in the Proforma Invoice.
• Import duties, taxes and customs clearance in the destination country are the buyer's responsibility unless otherwise agreed.
• We handle full export documentation from China.

Any special return or refund requirements must be agreed in writing (WhatsApp or email) before the order is placed. This policy may be updated; the version in effect at the time of your order confirmation applies to that order.
