How to connect wireless headphones to Xiaomi Redmi 7

Today’s smartphone users are increasingly turning away from wires in favor of wireless accessories, and owners of the popular Redmi 7 are no exception. The wireless connection allows freedom of movement, sports or moving around the house without being distracted by intricate cables. However, the process of initial pairing sometimes raises questions for those who first encounter Bluetooth technology on Xiaomi devices.

To successfully sync your Redmi 7 with the headset, you need to understand the basic principles of the data protocol and correctly activate the detection mode on both devices. In this article, we will discuss each step in detail, eliminating possible errors, and also consider the nuances of setting the audio profile for maximum playback quality.

Equipment preparation and activation of modes

Before starting the procedure, make sure that your Xiaomi Redmi 7 smartphone is at least 20-30% charged, as the process of finding devices and establishing a connection can consume energy.It is also critical that your headphones are fully charged, since in low-charge mode some models may not switch to pairing mode or quickly shut down.

The first thing you need to do is activate visibility on the headphones themselves. Unlike wired accessories, wireless models require manual search activation, usually by pressing the on button or a special pairing button for 5-7 seconds until the indicator flashes blue and red or flashes white quickly.

If you use TWS-Headphones (True Wireless Stereo) in the case, the procedure may be different: sometimes you need to take both headphones out of the charging case at the same time, after which they will automatically go into the waiting mode of connection. In some cases, especially for new devices, the mating mode is activated automatically when first removed from the package.

⚠️ Note: If the indicator on the headphones does not flash quickly or does not burn alternately with different colors, then the pairing mode is not activated, and the phone will not be able to detect them.

Setting up Bluetooth interface in MIUI

The MIUI operating system installed on Redmi 7 has a convenient and functional interface for managing wireless connections. To access the necessary settings, unlock the smartphone screen and find the Settings icon on your desktop, which looks like a gear.

In the menu that opens, you'll need to find the connection section. Depending on the firmware version, this item may be simply called "Bluetooth" or be inside the Connection and Sharing category. After you go to the menu, make sure that the activation slider is moved to the "On" position.

The system will automatically start scanning the space for available devices, at which point a list of gadgets will appear on the screen, and if your headphones are properly placed in visibility mode, their name should appear in the list of "Available devices".

⚠️ Warning: Do not try to connect to a device if it is already paired with another phone nearby - this can cause address conflict or automatically reconnect to a previous host.

To speed up the process, you can use the notification curtain: swipe from top to bottom to open the quick access bar, and (click and hold) the Bluetooth icon. This action immediately throws you into the desired settings menu, bypassing the main menu of the system.

The interface and authorization process

When the name of your headset appears on the list of available devices, tap it with your finger. At this point, Redmi 7 will send a pairing request. If the device requires confirmation, it may appear on the smartphone screen. PIN-code (usually 0000 or 1234) that must be entered or simply confirmed by clicking OK».

The process of installing a secure connection takes 3 to 10 seconds, during which time the system exchanges encryption keys and determines supported profiles, such as A2DP for music or HFP for calls, and successful completion of the operation will be confirmed by the appearance of the “Connected” status under the device name and the characteristic audible signal in the headphones themselves.

Sometimes the system may ask permission to access contacts and call logs, and if you plan to use the headset for conversations, you must agree to this request, otherwise the person will not hear you, and you will not see the name of the caller.

Advanced audio and codec settings

Once successfully connected, Xiaomi Redmi 7 allows you to flexibly adjust your audio settings. To do this, click on the gear icon or the arrow to the right of the name of the connected headphones in the Bluetooth menu.

You can activate or disable specific profiles in this menu, for example, if you only need headphones to listen to music in silence, you can turn off your Media Sound or System Sound profile, leaving only playback active, which is useful if you want to hear the navigator through the speaker and listen to music with headphones.

Modern headphones can support high-resolution codecs such as aptX or LDAC, which provide better sound quality compared to standard SBC. If your headphones support these technologies, you can select a priority codec from the “Additional” menu (often hidden in the engineering menu or available through third-party applications).

Also available in this section is the “Two Audio Devices” feature, which allows you to stream audio to two pairs of headphones simultaneously, which is handy when you want to watch a movie with a friend using two separate devices connected to the same Redmi 7.

Managing Notifications and Buttons

One of the key features of the MIUI integration is that it can control the media player and calls through the buttons on the headset, but the way these buttons work depends on how the player app or phone book responds to signals.

In Bluetooth settings, if you go to a particular device's menu, you can see the switches for Media Audio and Phone Sounds. If you turn off the first item, the track switching buttons on the headphones will stop working, but the sound of the call will come in, so you can flexibly configure the device to suit your needs.

For more advanced management, you can use the Mi Remote app or third-party utilities from Google Play that allow you to reassign button functions. For example, double tap can start the voice assistant Google Assistant, and triple tap can return the previous track.

⚠️ Note: Some budget models of headphones have a fixed logic of buttons, which cannot be changed by the software of the phone, since it is sewn into the microcontroller of the headset itself.

Solving Common Connection Problems

Despite the technology's fine-tuning, users sometimes run into difficulties. If the Redmi 7 can't see the headphones, even though they're on, try rebooting Bluetooth on the phone: turn off and turn on the slider again. Also helps to reboot the smartphone itself, which clears the cache of network services.

A common problem is the desynchronization of the left and right headphones in the TWS-In this case, you need to reset the headphones to the factory settings (usually this is done by holding the buttons on both headphones simultaneously outside the case), and then remove the device from the list of stored in the phone and connect again.

If the sound is interrupted or of poor quality, check the distance to the source of the signal. Wall obstructions or the human body can weaken the signal. Also try to turn off the option "Absolute Volume Level" in the developer settings, if any, as the conflict of volume levels of the phone and headphones often causes distortions.

In the case where the phone sees the device but writes a “failed to hide” error, it is possible that the Bluetooth module memory is full of old connections. Go to Bluetooth settings, click on the gear icon next to old, unused devices, and select “Cancel pairing” or “Forget device”.

Optimization of energy consumption

The constant operation of the Bluetooth module can affect the battery life of the Xiaomi Redmi 7. MIUI system has aggressive energy saving algorithms that can forcibly turn off background processes, including connection to headphones if you rolled the music player.

To avoid disconnection, go to the battery settings, find your music player (or messenger if you listen to voice) in the application list, and set the "No Limits" mode, which will prevent the system from "sleeping" the application.

It’s also worth noting that using high-resolution codecs (aptX HD, LDAC) increases the power consumption of both the phone and the headphones. If you’re on the go and the charge is running out, it makes sense to switch to the developer’s SBC codec settings to save energy.

💡

Save profile: After the first successful setup of all parameters (codecs, profiles) do not delete the device from the phone’s memory, even if you do not use it temporarily to save the configuration.
