Xiaomi Air 2S: How to check the originality of headphones in 10 minutes

Xiaomi Air 2S wireless headphones remain among the most popular in the segment due to the combination of price, sound quality and functionality. However, high demand is generating a flood of fakes — from rough copies to near-perfect replicas that are difficult to distinguish with the naked eye. According to AliExpress and Wildberries, up to 30% of offers at these sites can be counterfeit, especially if the price is below the market by 20% or more.

In this article, we will discuss 7 working methods of checking that will help detect fake before buying or refund money if you already have a fake in your hands. You will learn what to look at in the package, how to check the serial number through official Xiaomi services, what sound and connection tests detect copies, and why even original headphones can behave suspiciously after firmware. All methods are tested on lots of 2022-2026 and are relevant for models with the index TWSJBL03WM (official article).

1. Packaging check: 5 parts that give out a fake

The box is the first and most obvious sign of counterfeiting. Counterfeit manufacturers often save on printing, so even visually perfect packaging can have critical flaws.

• 📦 Print quality: original text and logos are clear, without blurring. Counterfeiting often has pale colors, uneven fonts or misaligned elements (for example, the Mi logo can be crooked).
• 🔍 Hologram: On the front of the original box, there's a holographic transfusion sticker, which is either missing from the fakes, or it's just a shiny, shiny film without the fakes. 3D-effect.
• 📏 Box sizes: the original packaging has exact dimensions 105×105×40 - Even if it's a deviation 2–3 mm - sign of a copy.
• 🔢 Barcode and article: at the bottom of the box should be a barcode that leads to the official product Xiaomi Air 2S (It's checked through apps like Barcode Scanner. TWSJBL03WM — mandatory.
• 📄 Documentation: the original contains a brief instruction in several languages (including Russian) with Xiaomi seal.

⚠️ Warning: some vendors only replace the box, and the headphones themselves remain fake, so checking the package is a necessary but not sufficient step.

Serial number: how to check through official databases

Each pair of Xiaomi Air 2S has a unique serial number (S/N), which can be checked through the manufacturer's services.

• 📦 On the box (on a barcode sticker).
• 🎧 On the headphones themselves (under the cover of the charging case or on the inside of one of the headphones).
• 📱 In the Mi Home mobile application (in the section about the device).

To check, go to Xiaomi Verify's official website and enter the serial number. The original device will display the Mi True Wireless Earphones 2S model, production date and warranty status. If the site shows an error or shows a different model, you're 100% fake.

⚠️ Note: some scammers also fake serial numbers using data from real devices. If the check was successful, but the headphones behave strangely (for example, quickly discharge or have a bad sound), perform additional tests from the following sections.

💡

Take a picture of the serial number from the box and headphones before you buy it, and if the seller refuses to provide this data, it is a reason to doubt the originality.

External inspection: materials, assembly and hidden marks

The original Xiaomi Air 2S is characterized by high quality build and materials used.

• 🔧 Charging case: the original lid opens smoothly, without creaking, and magnets securely lock it in a closed state.
• 🎨 Color: headphones should be matte, without paint tints. The original has no gaps between plastic parts, and the seams are almost invisible.
• 🔋 Charge indicators: the original headphone case has 4 white LEDs (one on 25% charge each). Fakes often have 3-5 indicators of other colors (blue, green).
• 🏷️ Hidden tags: Under the touch panel on each headphone of the original is a microscopic inscription L/R (Left/right. The fakes don't have it or it's crooked.

Also pay attention to the weight: the original case weighs 35.8 g, and each headphone – 4.5 g Counterfeiting is often lighter by 10-20% due to cheap materials.

4. Connection and operation test: what should alert

Even if the headphones look like the original, their behavior when connected can give off a fake.

1. Interfacing speed: The original Air 2S connects to the phone in 2-3 seconds, and fakes often “think” 10-15 seconds or require manual selection from a Bluetooth device list.
2. Device name: In the Bluetooth list, the original appears as Mi True Wireless Earphones 2S. The fake name may be different (for example, Air2S Pro or Xiaomi TWS).
3. Sensor work: On the original headphones, double-touching on the sensor turns the music on/off, and holding on activates the voice assistant. For fakes, gestures often go crooked or don't work.
4. Sound delay: the original has a latency of no more than 100 ms (imperceptible to the ear). In fakes, the delay can reach 300-500 ms, which is noticeable when watching a video.

⚠️ Note: if the headphones are connected as LE-Audio Device or have characters like #, * in the title, this is a sure sign of a fake. AAC, Fakes often only work through SBC (Checked in Bluetooth settings on Android).

5. Sound tests: how to hear the difference between the original and fake

Sound is what Xiaomi Air 2S is buying for, and that's where fakes lose the most.

• 🎵 Bass: The original has deep but clear basses without "drumping" and fakes often produce a dirty low-frequency sound that smears the rest of the frequencies.
• 🎶 High frequencies: original upper range (from 10 kHz) sounds clean, without hissing. Fakes on high notes have unpleasant squeaking or distortion.
• 🔊 Volume: the original produces up to 100 dB without distortion. Counterfeiting starts to wheez at 70-80% of volume.
• 🎤 Microphone: original voice is heard clearly even in a noisy place. In copies, the microphone often "muffles" the sound or transmits an echo.

For objective verification, use test tracks:

• Sweep 20–20kHz (frequency range check)
• Pink Noise (detects distortions at medium frequencies)
• Bass Test 40Hz (Low Frequency Quality Assessment)

Critical sign of fake: if you listen to a track with a frequency of 1 kHz in the headphones heard background noise (like the hissing of a radio), the device is exactly unoriginal.

6.Verification through the Mi Home app: hidden features of the original

The official Mi Home app (available for Android and iOS) not only allows you to control your headphones, but also to detect a fake.

1. Connect the headphones to the phone via Bluetooth.
2. Open the Mi Home and add a new device. The original Air 2S will automatically be identified as the Mi True Wireless Earphones 2S.
3. Check the available settings: 🔊 Adjustment of the equalizer (in fakes this option is not available). 🔋 Displaying the charge level of each headphone and case in percentage. 🔍 Search for headphones (Find Device).

If the app doesn't find the headphones or shows them as "Unknown Device," it's a complete fake, and the original version has a firmware update, which is not available to fakes.

💡

Even if the headphones connected to the Mi Home, but the settings are missing an equalizer or firmware - this is a rebranded fake based on another chip.

7. Analysis of price and place of purchase: where the risk of running into a fake is higher

Price is one of the most reliable indicators of originality, and as of 2026, the market value of the new Xiaomi Air 2S in Russia and the CIS is:

• 🛒 Official stores (Mi Store, Svyaznoy, M. Video): 4,500-5,500 ₽.

⚠️ Note: if a seller on a marketplace indicates that the product is “brought from China” or “without a box”, it is almost guaranteed a fake", "OEM-version" or "no logo".

Buy only from trusted sellers with a rating of at least 4.8 and a large number of reviews. Pay attention to the photo in reviews - often buyers post images of packaging or serial numbers, which can indirectly judge the originality.
