How to check headphones Xiaomi: diagnostics, sound tests and authenticity

Buying a wireless headset from a well-known brand always carries certain risks, especially if the transaction is made in the secondary market or through unverified sellers. Owners of Xiaomi gadgets often wonder how to check Xiaomi headphones to make sure they are authentic and healthy all functions. Modern audio devices are complex electronic systems where even a minor malfunction can spoil the experience of use.

Poor build or software failures may not occur immediately, but only after a few days of use, which is why a visual inspection is not enough to fully assess the condition of the device. You will need to perform a comprehensive diagnostic, including checking the Bluetooth connection, testing speakers at different frequencies and analyzing the operation of the built-in microphones.

In this article, we will examine all the stages of verification, from external inspection to the use of specialized software, you will learn how to distinguish the original from a cheap copy and identify hidden defects that are not noticeable with a cursory glance.

Visual inspection and configuration check

The first step in any diagnostics is a thorough external inspection of the device. The case of the original Xiaomi headphones, whether popular Redmi Buds or flagship Mi True Wireless, always assembled qualitatively. There should be no gaps on the surface of the plastic, sticking out glue or traces of sloppy soldering. Pay special attention to the places where the charging case cover is connected to the main body - the backlash should be minimal, and the latches should work clearly.

Be sure to check the availability and quality of the markings. Original products have the MI logo or Redmi labeled with a laser or high-quality printing, they are not erased by a finger. On the bottom of the case or on the headband (for full-size models) should be a sticker with the serial number, model and certification marks. The text on the label should be clear, without grammatical errors and typos.

⚠️ WARNING: If you notice blurry fonts on the package or device itself, errors in brand spelling (such as "Xoaomi" or "Redny"), or the absence of protective films on charging contacts, this is a sure sign of counterfeiting.

The package also plays an important role: In addition to the headphones themselves, the box should contain a charging cable (usually a Type-C or Micro-USB) and interchangeable mounts of different sizes. The cable should be dense, without the smell of cheap plastic, and the connectors should sit tightly in the ports. The absence of any elements or replacing them with frankly cheap counterparts suggests that you are not the original product.

Connection with the device and Bluetooth verification

After an external inspection, you need to move to the software part of the check. First, remove the headphones from the case and turn on Bluetooth on your smartphone. Xiaomi's original devices often support the MIUI Fast Connect feature, when the case cover opens next to the phone, an animation window with a charge level pops up. However, this feature works stably only on smartphones with a MIUI shell or HyperOS.

If you don't have an automatic connection, find the device in the list of available networks. Pay attention to the name: it should exactly match the model indicated on the box. After successful pairing, go to the Bluetooth settings and check the available profiles. For full operation, A2DP (for high-quality audio) and HFP/HSP (for headset and microphone) profiles should be active.

An important step is to check the stability of the connection. Step away from the phone at a distance of 5-10 meters, preferably with wall-like obstacles. The sound should not be interrupted, and the communication should be broken. If you see constant interference, stuttering or desynchronization of the left and right channel at a close distance, this may indicate a malfunction of the Bluetooth module or a poor quality of the antenna in a fake.

For deeper verification, you can use special applications like Bluetooth Scanner or nRF Connect, which allow you to see the connection specifications, signal strength (RSSI) and protocol version. Low signal strength in the vicinity of the source often indicates a defect.

Testing of sound quality and microphone

The most subjective, but important, step is to check the sound. You need to listen to tracks of different genres, paying attention to the details. In high frequencies, there should be no unpleasant whistle or "sand", and the bass should be elastic, not humming. Use high-quality audio files without strong compression to assess the real potential of the audio track.

Special attention should be paid to checking the channel balance: play a monophonic sound or a special test track, where the voice is strictly in the center. If you hear a shift of the sound to the left or to the right, or one earphone is playing quieter than the other, this is a defect. Also check the noise cancellation (if it is declared): when you turn on the ANC mode, the background hum should be significantly reduced, rather than turning into a hiss.

The microphone is checked by recording voice messages or talking on the phone in different conditions. Go outside or turn on the fan to create background noise. The interviewer should hear your voice clearly, without severe distortion and the effect of "aquarium". In cheap copies, microphones often work extremely quietly or transmit sound with strong metallic sounds.

For an objective assessment, you can use online services to check your hearing and frequency range. Run the sound from 20 Hz to 20 kHz. If you stop hearing sound at frequencies above 14-15 kHz (which is normal for adults), this is one thing, but if the cliff occurs abruptly or is accompanied by a crack, this is a sign of a malfunction of the speaker membrane.

Diagnostics of battery and charging case

Autonomy is a key parameter for wireless devices. Checking starts when you remove the headphones from the box. Even if the lights are full, discharge the devices completely, actively using them to listen to music or watch videos. Check the time of operation and compare it with the declared manufacturer.

The charge case also requires attention. It needs to be charged with a steady current without overheating too much. When you install the headphones in the case, the indicators should light up, signaling the start of charging. If the headphones do not charge inside the case or the charge "flies" in a couple of hours of downtime, the problem may be in the power controller or the battery itself.

Note the charging speed. Original Xiaomi devices usually support certain fast charging standards. If it takes an unnecessarily long time to fully recover capacity (more than 2-3 hours for a case), this may indicate the use of old or substandard batteries inside.

⚠️ Warning: If the headphone or case gets very hot during charging or use, stop using immediately.This may indicate a battery defect and a risk of fire.

Checking touch control and buttons

Modern models like the Xiaomi Buds 3 or Redmi Buds 4 come with touch panels, while others may have mechanical buttons.Check the response to every touch.The sensor should respond to light touch, but should not be triggered by accidental touching of hair or clothing.Mechanical buttons should have a clear, resilient click without jamming.

Test all available gestures: single touch (pause/playback), double (next track), triple (previous track) and hold (activation of voice assistant or switching modes). Delays in reaction or the need for strong pressure indicate wear or failure of the sensor module.

It's important to check the voice assistant, and when you activate it with a voice or button, the smartphone should immediately go into command standby mode, and if the assistant is late or not responding at all, it's possible that the headphone software is not working properly.

Using applications for deep verification

For Xiaomi and Redmi smartphone owners, the best diagnostic tool is the official Xiaomi Earbuds app (or built-in MIUI functionality), which allows you to see the exact percentage of charge of each headphone separately, which is impossible to do in the standard Bluetooth menu, and the application will show the firmware version and offer to update it.

You can calibrate your touchscreen and check your connection status through the app. If the app doesn't see the headphones, even though the phone does, it's a wake-up call. For iOS or other Android smartphones, there are universal utilities like Assistant for Mi or Dalali that can also provide advanced information about the device.

Don't forget to check for firmware updates. Manufacturers regularly release bug fixes that improve connection stability. If a new version of the software is available through the app, be sure to install it by putting your headphones in your case and connecting your phone to the network.

Comparison with the original and identification of counterfeits

If you have the opportunity to compare a suspicious device to a known original, do so. Pay attention to the weight: the originals are often heavier due to the use of quality batteries and materials. The plastic of fakes can be more glossy, slippery or, conversely, excessively rough.

Check the serial number on the manufacturer's website or through the helpline. Although scammers have learned to copy valid numbers, sometimes they use one code per thousand devices. If the number does not break through or is listed as "sold" in another region many times ago, this is cause for doubt.

Price is also an indicator: the cost of new models rarely falls below a certain threshold. If you are offered flagship Mi True Wireless Earbuds at a price three times lower than the market, the probability of buying a counterfeit goes to 100%.
