How to Check Xiaomi Wireless Headphones: 7 Key Tests Before Buying and In Use

Xiaomi’s wireless headphones are some of the most popular accessories on the market, thanks to a combination of price, quality and functionality. However, even proven models like the Redmi AirDots, Mi True Wireless Earphones or Xiaomi Buds 4 Pro can encounter defective instances, fakes or hidden defects. Buying headphones from your hands, in informal stores or even in a box with damaged packaging, you risk getting a device with problems with sound, connectivity or autonomy.

This article will help you check your Xiaomi headphones at all stages, from inspection of the package to testing sound, microphone and battery, we will understand how to distinguish the original from a fake, what features you must check before buying, and how to diagnose malfunctions during operation. Particular attention will be paid to models with active noise reduction (ANC), Bluetooth touch control and support 5.2/5.3, Because their checks have nuances.

1. Originality Check: How to distinguish real Xiaomi headphones from fake

Fake Xiaomi headphones are often indistinguishable from the original, but have the worst sound, battery and materials quality. The first thing to do is check the packaging and configuration. The original headphones are always sold in a tight box with a clear print, hologram and barcode, which can be checked through the official Mi Home app or on the Xiaomi website.

Pay particular attention to:

• 📦 Box quality: the original has no gaps, no curves, no blurry text, and the Mi or Redmi logo should be clear, without shifting the paint.
• 🔍 Hologram and sticker: the box should have a protective sticker with a unique code (if it is unpatched, the inscription remains). VOID or OPEN).
• 📱 QR-code: when scanning, it must lead to the official model page on mi.com (not on AliExpress or an unknown resource!).
• 🔋 Charging cable: in the set of original headphones is always branded USB-C MicroUSB cable with the Mi logo.

If you buy headphones from hand, ask the seller to show you the box and documents. Counterfeit products are often sold without a package or with a copy of the check. Also check the serial number on the case itself - it must match the number on the box and in the Mi Home app (if the model supports binding).

⚠️ Fakes often imitate Xiaomi Buds models 3/4 Pro and Redmi AirDots 3. Original headphones weigh strictly to specification (e.g. Buds) 4 Pro — 4,8 d each headphone, case — 42 Weigh them on the exact scales if you have doubts.

External inspection: what should alert you during a visual inspection

Before you plug in your headphones, carefully examine them for mechanical damage, backlashes and build defects.

• 🔄 Case cover: should open/close smoothly, without creaking. In the original models, the fixation magnet works clearly.
• 🔦 Charge indicator: when connected to a charge, it should light up (usually white or orange). If it does not burn, there may be a problem with the battery or board.
• 🧲 Magnets in headphones: put the headphone on a metal surface - it should hold on confidently. Weak magnets - a sign of fake or marriage.

Then check out the headphones themselves:

• 🎧 Grid speaker: should be flat, without dents or traces of glue. ANC (For example, Buds 3 Pro, the grid often has additional dust protection.
• 👆 Touch buttons: press them, they should have subtle tactile clicks, and if they fail or fail, it's marriage.
• 🔌 Charging contacts: Headphones and case should be clean, without oxidation.

If the headphones have already been in use, check the earbuds (silicone nozzles) - they should not be deformed or covered with plaque. Xiaomi's original earbuds usually have a logo on the inside.

💡

To check the tightness of the headphones, blow into the microphone hole - if you hear a whistle or resistance, then there is no damage to the membrane inside.

3. Testing of connection and compatibility with devices

One of the key tests is to check the stability of the Bluetooth connection. Xiaomi headphones must quickly connect to Android smartphones (especially devices). Xiaomi/Redmi/POCO) and maintain profiles A2DP (sound-wise), AVRCP (reproduction control) and HFP (call-in).

Step-by-step instructions for checking the connection:

1. Turn on Bluetooth on your smartphone and open the case cover (earphones should automatically go into pairing mode).
2. In the list of available devices, find the model of your headphones (for example, Mi True Wireless Earphones 2).
3. Connect and check if the headphone charge level is displayed in the Android status bar (the original models have this feature working).
4. Step away from your smartphone 5-10 meters (no obstacles) – the sound should not be interrupted or distorted.

If the headphones don't connect, try:

• 🔄 Reset the headphone settings (usually by pressing the touch button for 10-15 seconds before flashing the indicator red/white).
• 📱 Update the firmware of the smartphone (sometimes connection problems are solved by updating the Bluetooth stack).
• 🔌 Check headphones with another device (such as a laptop or tablet).

For dual-connected models (like Buds 4 Pro), check the ability to connect to two devices at the same time. To do this, connect the headphones to your smartphone, then activate Bluetooth on the second gadget and select the headphones in the list.

Make sure the headphones are in pairing mode (white indicator flashes)

Check compatibility with your version Android/iOS

Test the communication range (minimum 5 meters without interference)

Check the display of the charge level in the status bar-->

Audio quality check: how to detect defects in speakers

Sound quality is the main criterion for headphones. To objectively assess it, use test tracks with different frequencies and check:

To check for active noise reduction (ANC) (if there is a model):

1. Activate the mode. ANC in headphone settings (via Mi Earphones or Mi Home app).
2. Turn on background noise (such as a working vacuum cleaner or fan).
3. How well low-frequency noise is suppressed (ANC It is less effective at high frequencies, such as voices).

If the sound is interrupted or interference is heard, the reasons may be as follows:

• 🔋 Battery discharge (charge your headphones to 100%).
• 📶 Interference from other wireless devices (Wi-Fi router, microwaves).
• 🔊 Damaged speaker (check on another device).

⚠️ Note: Redmi AirDots models 2/3 There's a common defect where one earbud starts to sound quieter over time, and it's due to wear and tear on the speaker. Check the channel balance at maximum volume -- if the difference is noticeable, the headphones are defective.

5.Mic test and call function

Many users forget to check the microphone, and poor voice transmission can make headphones useless for calls.

1. Connect your headphones to your smartphone and call another number (or use a voice recording service like Vocaroo).
2. Speak to the microphone at normal volume, then check the recording.
3. Ask the person to rate the quality of your voice (no noise, echo, or muting).

If the microphone is not working well:

• 🧹 Clean the microphone hole from dust (use a soft brush or compressed air).
• 🔄 Reconnect the headphones to the phone.
• 📱 Check the microphone settings in the Mi Earphones app (if supported).

For microphone noise-canceling models (such as the Xiaomi Buds 4 Pro), check how they handle background noise.

1. Enable voice recording in a noisy place (such as outside).
2. Activate the noise suppression mode in the settings.
3. Compare the recording with the noise cancellation switched off and on.

Important: Xiaomi headphones often have microphones on the headphone leg (near the speaker) or on the end of the tail. If the microphone doesn't work, check if it's full of dirt - this is the most common cause of malfunction.

6. Checking the battery and the time of autonomy

Autonomy is one of the key parameters of wireless headphones, and even if the seller claims that the battery is "like new," you have to test it yourself.

Step 1: Check the charge of the case and headphones

• 🔋 Connect the case to the charger and see how quickly the indicator lights up (in the originals it lights up immediately).
• 📊 In the Mi Home or Mi Earphones app, check the percentage of charge of each headphone and case (if the model supports display).
• ⚡ If the headphones discharge in a few minutes - this is a sign of a worn-out battery.

Step 2: Real-time Testing

• Charge your headphones and case to 100%.
• Turn on the music at medium volume (50–60%).
• Note the time after which the headphones will discharge (compare with the stated in the specification).

For fast-charging models (such as the Xiaomi Buds 4 Pro), check how much percent of charge is recovered in a 10 minute case. In original headphones, this is usually 20–30%.

⚠️ Note: If the case of Xiaomi headphones stopped charging the headphones, but it is charging from the cable itself - the problem is in the contacts inside the case.

7. Diagnostics of additional functions (sensory control, firmware, water protection)

Modern headphones Xiaomi equipped with additional features that also need to check:

Sensory management:

• 👆 Touching: One/Double/Triple Pressing must be triggered the first time.
• 🎵 Gestures: Check swipes for volume control (if supported).
• 🔇 Pause/playback: when removing one earphone, the music should be paused (Wear Detection function).

Firmware and updates:

• 📲 Install the Mi Earphones app and check for firmware updates.
• 🔄 If the headphones aren’t updated, it may be a fake or a model for another region.

Water protection (IP-certification):

• 💧 If the model is protected IPX4/IP54 (For example, Xiaomi Buds 4 Pro), test it by slightly moistening the headphones with water (don't dive.
• ⚠️ Don’t confuse water protection with water protection – headphones aren’t designed for swimming!

Multipoint (connection to two devices):

• 📱 Connect your headphones to your smartphone and laptop at the same time.
• 🔊 Check how they switch between sound sources.
