How to Check the Originality of Xiaomi Redmi Airdots Headphones 2: Complete Guide with Tests and Codes

Why is it so important to distinguish the original from the fake?

Xiaomi Redmi Airdots 2 headphones remain among the most popular wireless headsets in the budget segment — and that is why they are counterfeited more often than others. According to AliExpress and Wildberries, up to 40% of the market offers are counterfeit, which is almost indistinguishable from the original. But the difference in sound quality, operating time and safety is obvious: fakes often give out distorted bass, quickly discharge and can even explode when charging due to poor-quality batteries.

In this article, we'll look at 10 reliable ways to verify originality, from visual inspection to hidden service codes that only Xiaomi engineers know. You'll learn how to tell the difference between a fake before you buy, what parts a fake gives off when unpacking, and why even a box can tell more about headphones than a seller. And at the end, an FAQ that answers the most controversial questions, such as why original headphones might not connect to the Mi Home app.

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

The original Redmi Airdots 2 box is the first and most reliable indicator of authenticity. The manufacturer pays attention to even small things that are difficult to fake. Let's start with the material: the original packaging is made of dense cardboard with a matte coating that does not imprint on the fingers. Fakes often use glossy or too thin cardboard, which crumples with light press.

Pay attention to the print and fonts:

• 🔍 Redmi logo: the original logo is sharp, with flat edges and deep black paint. Counterfeiters often have blurred contours or grayish shades.

Another key thing is the film on the box, and the original headphones are packed in a transparent film with perforations on the sides, which can be easily removed without scissors, and the fakes have either too tight or not at all.

💡

If the seller refused to show the box before the purchase, it is a reason to be wary. The original Redmi Airdots 2 always sells in branded packaging, even if they are "b/u, but as new."

Visual inspection of headphones: what should alert?

When the headphones are in hand, we start with a detailed inspection. Let's start with the weight: the original Airdots 2 weighs 4.1 grams each (checked on a jewelry scale), counterfeits are often 0.5-1 g heavier due to cheap body materials.

Next, check:

• 🎨 Color and texture: the original is matte with a slight roughness; fakes are either glossy or too rough to the touch. The color should be uniform; fakes often show stripes or spots.
• 🔋 Charging Indicators: On the original headphones, LEDs burn red when charged and white when fully charged. Fakes can have blue, green, or flash chaotic colors.
• 🔊 The grille is dynamic: the original one is metal, with small holes (0.3 mm); for fakes, it is plastic, with large holes (0.5-0.7 mm), which are visible to the naked eye.
• 🧲 Magnets in a case: the original headphones are fixed in a case with a slight click. If they dangle or fall out, it's fake.

Pay special attention to the control buttons. On the original Airdots 2, they are recessed into the body and pressed with slight resistance. For fakes, the buttons often protrude above the surface or fall through when pressed.

3.Serial number check: official Xiaomi services

The most reliable way to confirm originality is to check the serial number (S/N) through the official services of Xiaomi. The number is indicated on the box, inside the case (under the battery) and on the headphones themselves (under the speaker grille).

Methods of verification:

1. Xiaomi official website: Go to the checkout page. Enter S/N (14 characters) in the Serial Number field. If the headphones are original, the system will show the model (Redmi Airdots 2) and the date of production.
2. Mi Home: Connect your headphones to your phone via Bluetooth. Open Mi Home → Device Profile → Info. Compare the S/N in the app to the number on the box. They should match.

Warning: If the serial number on the box and in the app don't match, it's 100% fake, even if all the other signs point to the original.

💡

If the seller refuses to provide the serial number before the purchase is a sure sign of a fake. The original headphones always have a unique S/N that can be checked.

4. Connection and Sound Test: What Does Fake Out?

The original Redmi Airdots 2 connects to a phone via Bluetooth 5.0 protocol with support for SBC and AAC codecs. Fakes often use outdated Bluetooth 4.2 or cheap chips without AAC support, which is immediately noticeable in the sound quality.

How to check:

• 📱 Device name when connected: Original headphones are displayed as Redmi Airdots 2 or Mi True Wireless EB2 Basic. Fakes can have names like TWS Earbuds, Wireless Headset or Cyrillic symbols.
• 🔊 Sound quality: Original: clear high and medium frequencies, bass deep but not "bullying." Fake: sound dirty, bass overloaded, high frequencies wheezing.
• 🎵 Microphone test: call another phone and check how you're heard. Original headphones suppress noise, fakes transmit all foreign sounds.
• 🔋 Time of operation: the original holds 4 hours on a single charge (with a case - up to 12 hours.

Another test is audio delay. Play a YouTube video and check the synchronization of the sound with the picture. The original Airdots 2 has minimal latency (up to 100 ms), fakes can reach 300-500 ms, which is noticeable when watching movies.

5 Hidden Service Codes: What Only Xiaomi Engineers Know

Few people know, but Redmi Airdots 2 has hidden service commands that allow you to get technical information about the headphones, which are not officially documented, but they are used by service centers for diagnostics.

How to activate:

1. Put the headphones on the phone.
2. Open the dial and type in: ##4636##
3. Select Bluetooth Information.
4. Find the Redmi Airdots list 2 Check the settings: Address: should start with 78:11:DC (Xiaomi's proprietary prefix Version: the original has firmware 1.4.0_1123 Features: There must be a point LE Audio (fakes don't have it).

Another code to check the battery:

##3644633##

Once you enter it, you will see a menu of battery capacity information, and the original headphones will show 43 mAh for each headphone and 300 mAh for the case, and fakes often underestimate these values (for example, 30 mAh and 200 mAh).

💡

If nothing happens after you enter the code, it's a sign of a cheap Bluetooth chip that doesn't support service commands, and 99 percent chance it's fake.

6.Verification through the Mi Home app: why might it not work?

The official Mi Home app must recognize Redmi Airdots 2 automatically when connected.

If the headphones don’t appear in the Mi Home, the reasons may be as follows:

• ❌ Fake: fakes do not have a Xiaomi chip, so the app does not see them".
• ⚠️ Outdated firmware: Original headphones with firmware older than 1.2.0 may not be supported by new Mi Home versions.
• 📱 Phone region: If your Xiaomi account is tied to a region where Airdots 2 is not sold (e.g. Europe), the app may not recognize them.

How to solve the problem:

1. Update your Mi Home to the latest version.
2. Try connecting via another phone (preferably with MIUI).
3. Reset the headphones to factory settings: Hold the buttons on both headphones for 10 seconds until the red light flashes.

Important: Even if the headphones don't show up in the Mi Home, that doesn't always mean fake. For example, some parts for the Chinese market don't support the global version of the app. In this case, check them through the serial number on Xiaomi's website.

💡

Not being in the Mi Home is not a sentence, but if the headphones don't pass S/N and have other signs of a fake, that's a reason to return them to the seller.

7. Where to buy so as not to run into fake?

Even if you know all the features of the original, you still have the risk of buying a fake if you choose an unreliable seller, and here's the ranking of sites by trust level (from the safest to the riskiest):

If you are buying on AliExpress, you must:

• 📸 Request a photo of the box with the serial number before payment.
• 🎥 Ask for video with connection and sound check.
• 🔍 Check the reviews with the photo – often buyers post evidence of fakes.

⚠️ Warning: if the seller offers "original headphones without a box" or "70 percent off" is almost always a hoax.The original Redmi Airdots 2 is not sold without packaging, as the serial number on the box is part of the warranty.
