1. Official channel purchase: First of all, it is recommended to purchase JBL headphones through official channels or licensees to ensure the authenticity and quality of the products.
2. Verify the product serial number: Each JBL headset has a unique product serial number. You can find the product verification page in JBL official website, and enter the earphone serial number for verification. If the serial number is invalid or has been used, it may be a counterfeit product.
3. Inspection of product appearance and details: Carefully check the appearance and details of headphones, and compare the product pictures and descriptions on official website. Pay attention to whether the product identification and trademark are clear and accurate, and whether the packaging box, wires and accessories are consistent with the official description. Counterfeit products are usually defective in appearance or do not meet official standards.
4. Sound quality and function test: test with headphones to check whether the sound quality and various functions are normal. The sound quality and function of counterfeit products are usually obviously poor.
5. Reputation of purchasing channels: When purchasing JBL headphones from third-party platforms or individuals, you should pay attention to the seller's reputation and word of mouth. Choose sellers with good evaluation and high credibility, and try to avoid buying products with unknown sources.
If you still have questions or doubts about the authenticity of the purchased JBL headphones, you can contact JBL's customer service department to provide them with relevant information and consultation.
