Xiaomi Air 2 SE: 12 signs of counterfeiting

Xiaomi Air 2 SE wireless headphones remain among the most popular in the budget segment due to the balance of price, sound quality and battery life. However, their high demand has led to a massive emergence of fakes – from rough copies from Aliexpress to visually indistinguishable replicas that only give themselves away in the process of use. According to Roskachestvo, up to 30% of Xiaomi headphones sold on marketplaces are counterfeit.

In this article, we will discuss 12 key features that distinguish the original Air 2 SE from a fake, from checking the packaging to analyzing the sound signature. You will learn what details are often missed by fraudsters, how to check headphones through the official Mi Home app, and why even visually identical copies give out the lack of support for the LHDC protocol (high-resolution codec, which is only in the original).

1.Packaging: 5 parts that give off a fake

The first thing that catches the eye is the box: the original Xiaomi Air 2 SE comes in minimalist white packaging with clear print and relief elements, counterfeits often save on cardboard quality, paint and embossing.

Here's what to look out for:

• 📦 Box material: the original is a thick, matte cardboard with a light glossy coating on the logo, and the fakes are usually glossy or too thin, sometimes with uneven edges.
• 🔍 Barcode and serial number: on the original box, the barcode is laser-coded (not erased by the nail), and the serial number is duplicated on the sticker inside.
• 🖼️ Headphone photos: the original image is clear, with realistic shadows, and copies often blurred contours or incorrect colors (for example, silver inserts instead of black).
• 📏 Box sizes: original — 10.5 × 6.5 × 3.2 See also: Fakes can be larger or already on the 2–3 mm.
• 🔖 Characteristics: original Chinese and English text, font smooth. Counterfeiting often contains errors in translation (e.g., "Noice Cancelling" instead of "Noise Cancelling").

Pay special attention to the film on the box. Xiaomi's original headphones are always sealed in a transparent film with the brand logo, which breaks with a characteristic crack, and counterfeits are often bypassed by ordinary tape or tape without embossing.

2.Serial number: how to check through Mi Home

The most reliable way to detect a fake is to check the serial number through the official Mi Home app.

1. Download Mi Home from Google Play or App Store.
2. Sign up or sign in to your Xiaomi account.
3. Go to the Profile section → My devices. → Add the device.
4. Select Headphones → Air 2 SE and enter the serial number from the box or from the headphone settings.

If the device is not located or you get a "Can't Add the Device" error, you're 100% fake, and the original headphones are automatically attached to your account when you first connect.

💡

If the headphones are already connected to the phone but don't show up in the Mi Home, try resetting them: pinch both touchpads for 10 seconds before the red light flashes.

Another way to do this is to check the serial number on Xiaomi Verify, enter the number in the IMEI/SN field and press Check. The original headphones will show the model, the date of production and the warranty status, and the fakes will show an error or a non-existent model.

⚠️ Warning: Fraudsters sometimes clone serial numbers from real devices if the number has been checked but the headphones are suspicious (e.g., quickly discharged or no support). LHDC), Ask the seller for a photo of the internal sticker with IMEI — It can't be faked without a body.

3. Appearance: 3 hidden marks of the original

Visually, the fake Xiaomi Air 2 SE is almost perfect, but there are details that scammers miss:

Pay special attention to the internal sticker under the charger case cover.

• 🔢 IMEI (It should match the number on the box)
• 📅 Date of production (format) YY-MM-DD)
• 🏭 Plant code (e.g. "Made in China by" AAC Technologies")

Counterfeit labels often lack or contain meaningless symbols, and if a seller refuses to provide a photo of the internal sticker, this is a reason to doubt the authenticity.

LHDC Sound and Codec: The Main Feature of the Original

The original Xiaomi Air 2 SE support codec LHDC (Low-Latency High-Definition Audio Codec, which provides high-resolution sound (up to 900 kbps) and fakes use cheap chips that only support basic codecs. SBC and AAC.

How to check:

1. Connect the headphones to your smartphone on Android 10+ or iOS 14+.
2. Install Developer Options (for Android) or Bluetooth Codec Checker.
3. Turn on music playback and check the active codec in Bluetooth settings.

If there is no LHDC on the list of available codecs, it is a fake, and the original supports aptX Adaptive, which 99% of copies do not have.

Additional sound indications:

• 🎵 Basses: the original is deep but not dirty. Counterfeits often have bulging low frequencies.
• 🎶 Scene of sound: the original gives a wide stereo, copies - "flat" sound without space.
• 🔊 Maximum volume: the original does not distort the sound at maximum, fakes begin to wheez.

⚠️ Note: Some fakes simulate support LHDC Bluetooth, but they are actually using it. SBC. To make sure, run the test in the Audio Test Tone Generator app - the original will reproduce frequencies up to 22 kHz without distortion, a copy - no.

5. Charging case: 4 differences that you can not hide

The case charger is one of the most forged parts, as it is more difficult to test indiscriminately, but there are signs that give off counterfeiting:

Pay special attention to the charge indicators:

• 🔋 Original: 4 white LEDs, light up sequentially when charging.
• 🔌 Fake: Often 3 LEDs or blue/red, can flash chaotically.

Another test is charging time: the original case charges headphones from 0 to 100% in 1 hour and 10 minutes; counterfeits usually do it in 40 to 50 minutes (due to a weak battery) or more than 2 hours (due to a cheap controller).

6. Software chips: what only the original can do

The original Xiaomi Air 2 SE is integrated into the Mi Ecosystem ecosystem and has unique features that fakes don’t have.

Functions that the original should support:

• 📱 Quick connection: when you open a case next to the Xiaomi phone, a pop-up window with a suggestion to connect appears (Mi Pop-up Connect technology).
• 🔊 Customization of sound in Mi Home: the original allows you to choose presets EQ (Bass, Voice, Balance).
• 🔍 Headphone search: The Mi Home app has a Find Device feature that shows the last connection location.
• 🎧 Automatic Shutdown: If you remove one earphone, the music is put on pause (for fakes, it often works with a delay or does not work at all).

The original also supports firmware through Mi Home. Go to the headphone settings in the app -- if there's a firmware update, that's a good sign. The fakes either don't have that item or they give an error when you try to update.

💡

If the headphones are not defined in Mi Home as "Air" 2 SE", a) is displayed as "Unknown Device" or "LE_Audio" — It is a fake, even if they are identical.
