Unless you buy an AirPods straight from Apple.com or an official Apple retail store, you should be worry to a certain degree on whether the AirPods are fake or genuine, specially if you bought them from a third-party seller on Amazon or eBay.com. AirPods are not expensive just because they are branded by Apple, these pieces of earbuds are expensive because a tremendous amount of money was spent by Apple on its research and development, with the inclusion of its Apple W1 chip for easy pairing and battery management. Because of this, it’s nearly impossible for Chinese cloners to make an exact replica of the Apple AirPods.

If by any chance you believe you’ve purchased a fake Apple AirPods, here are five ways you can confirm your doubt and investigate whether they’re genuine or a knockoff product…

Note: Although it’s very possible to identify whether a pair of AirPods is real or fake by just looking at them, it’s not a reliable way to do it. It’s been almost three years since Apple released the original AirPods and Chinese companies have gotten very smart at doing a physical replication of the product. So the best way of identifying whether a pair of AirPods are real or fake is a by checking the following features and characteristics found in a truly genuine pair of AirPods:

Check serial number on Apple’s website

The best way of spotting a fake AirPods is by matching the serial number on Apple’s website. On your web browser, if you navigate to checkcoverage.apple.com, you should be able to check a wide range of information regarding to your AirPods. This includes Valid Purchase Date; Telephone Technical Support; and Repairs and Service Coverage. If the serial number of your AirPods is not valid after you submit it to that page, you can be certain that the AirPods you have on your hands are fake.

You can find the serial number of your AirPods by opening the lid of charger and checking underneath them. In case you aren’t able to see those tiny letters, you can also find out the serial number by connecting your AirPods to your iPhone and navigating to Settings > General > About > AirPods.

Charger connector uses micro USB charging port

If you see that the pair of AirPods you’re holding in your hands have a micro USB port instead of the regular lightning commonly use in Apple products, then those pair of AirPods are definitely fake. Most AirPods replica use micro USB or USB-C for charging, while Apple exclusively uses their own Lightning connector.

No W1, H1 chip

When Apple first introduced the first-gen AirPods back in 2016, the AirPods were introduced with an embed chip which Apple called the W1 chip. This chip was developed in order to facilitate the registration of AirPods and iOS devices for end users. One of the benefit of the W1 chip is that it will quickly connect your Bluetooth device every time you use them, you do not have to be tinkering with settings in order to pair them. The other benefit of these chips (W1 and H1) is that they are very power efficient when it comes to usage. If your AirPods do not one of these chip, then they’re fake.
