Xiaomi Redmi Note 7 is still popular due to its balanced performance and reliable performance, but many users face difficulties when connecting wireless headphones for the first time β especially if we are talking about models with non-standard communication protocols (for example, Xiaomi AirDots or Sony WH-1000XM4). In this article, we will analyze all the nuances from basic synchronization to solving rare errors that are not described in the official documentation.
It is important to consider that the Redmi Note 7 runs on MIUI (versions 10-12), where the Bluetooth menu interface may differ from pure Android.In addition, some headphones require pre-preparedness - for example, resetting to factory settings or updating firmware. We will look at universal methods, as well as specific cases for popular brands.
1. Preparation of headphones and phone before connection
Before you start syncing, make sure both devices are ready to connect, and a common mistake users make is trying to connect to headphones that have not yet been turned into the pairing mode.
- π Charging headphones: Make sure the headphones have a charge level of at least 30, JBL Free X) refuse to enable low-charge search mode.
- π± Phone Update: Check the relevance of Redmi Note 7 firmware in the Settings menu β The phone. β System updates. Old versions. MIUI They may not support modern codecs. AAC or.
- π Reset previous connections: If the headphones were already paired with another device, delete them from memory (usually by holding the power button for 10-15 seconds).
Xiaomi models (such as AirDots Pro or FlipBuds Pro) may require the installation of the Mi Earphones app, which automatically updates the headphone firmware and adjusts the optimal sound settings, which can be downloaded from Google Play or AppGallery (if you use Huawei Mobile Services).
β οΈ Note: If your headphones support Bluetooth 5.0 and the Redmi Note 7 is equipped with Bluetooth 4.2, there may be problems with communication stability. In this case, try turning off high-resolution audio codecs in the developer settings (Settings). β Additionally. β For developers β Bluetooth codec).
2. Step-by-step instruction: how to connect headphones via Bluetooth
Now, to the process of connecting, follow the instructions carefully, and even a slight deviation (such as pressing a button early on the headphones) can cause a failure.
- Activate Bluetooth on your phone: Open Settings β Bluetooth and move the slider to the βOnβ position. An alternative way is to swipe down the notification bar and click on the Bluetooth icon.
- Put the headphones in search mode: For most models, this is done by holding the power button (or touchpad) for 3-5 seconds until the indicator flashes (usually red and blue or white).
- Find the headphones in the list of devices: In the Bluetooth menu on the phone, the name of your headphones (for example, Mi True Wireless Earphones or WH-1000XM4) will appear.
- Confirm the pairing: If necessary, enter PIN-code (usually 0000 or 1234) Some models (e.g. Bose QuietComfort) may request confirmation on the headphones themselves (double tap on the touchpad).
Once you've successfully connected, you'll see "Connected" on your device list, and a headphone icon on your status bar, and you'll run any audio file or video to check if it's working.

3. Features of connecting headphones of different brands
Not all wireless headphones behave the same when paired with the Redmi Note 7. Consider the nuances for popular models:
| Brand/Model | Search mode | Whether an application is required | Frequent problems |
|---|---|---|---|
| Xiaomi AirDots (all versions) | Holding the touch button 5 seconds | Yeah (Mi Earphones) | Do not connect if there is a second headphone in the case |
| Apple AirPods (1β3 gen) | Open the case cover + button on the back panel | No. | Sound delays when watching video |
| Sony WH-1000XM4 | Holding the power button 7 seconds | Yes (Sony Headphones Connect) | No noise is used when connecting to MIUI |
| JBL Free X | Holding the button on both headphones | No. | Dissynchronization of left/right headphone |
Samsung Galaxy Buds headphones may require installing the Galaxy Wearable app, but it doesn't officially support Xiaomi.In this case, use the universal nRF Connect app for manual tuning.
β οΈ Note: If you connect your Apple AirPods Pro or AirPods Max headphones, turn off Auto Switch in iCloud settings (if the phone was previously linked to an Apple account). Otherwise, the headphones will spontaneously disconnect from the Redmi Note 7 when a number of devices appear on iOS.

If the headphones arenβt being identified, try taking them out of the case and putting them back in β sometimes this resets the Bluetooth moduleβs errors.
4. Solving common connection problems
Even if you follow instructions correctly, you can have failures, and here are the most common mistakes and ways to fix them:
- π Phone can't see headphones: Check if the headphone search mode is on (the indicator should flash fast, not slow). Reboot Bluetooth on your phone: turn off and turn on the module again. If it doesn't work, remove all the saved devices from the list and try to connect again.
- π΅ The sound is interrupted or delayed: This is a typical problem for the Redmi Note 7 due to a weak Bluetooth module. HD-audio in Bluetooth settings. Reduce the distance between the phone and the headphones (maximum 1-1.5 meters). Turn off Wi-Fi - sometimes 2.4 GHz channels conflict with Bluetooth.
- π Headphones discharge quickly: The fault may be the background process MIUI, which is constantly scanning devices. Turn off the Nearby Device Search function in Settings β Google β Devices and exchanges.
If the headphones are plugged in, but only one of them is sounding, reset the headphone settings (the instruction is usually in the user manual) and repeat the pairing. For Xiaomi AirDots, this is done by triple tapping the touchpad.
What if the headphones are connected but do not play the sound?
5. Sound optimization after connection
Successful connectivity is only half the battle, and to get the best sound quality, adjust the following settings:
- π§ Codec Choice: By Default MIUI use SBC β The most versatile, but not the best, codec. If your headphones support AAC or aptX, enable them in the developer settings (Settings) β The phone. β Version. MIUI β Press 7 times, then return to Additional β For developers β Bluetooth codec).
- π Equalizer: MIUI There is a built-in equalizer: Settings β Sound. β Equator. For bass, choose preset "Bas," for vocals, "Pop." For noise-producing headphones (like Sony). WH-1000XM4) It is better to disable the equalizer at all - it can conflict with the built-in settings.
- πΆ Communication Stability: If the headphones support Bluetooth 5.0 but the phone only 4.2, disable the dual connection (if any) feature.It allows the headphones to connect to two devices at the same time, but on older versions of Bluetooth this leads to breaks.
Important: Xiaomi AirDots 3 Pro headphones automatically switch to low power (and degrade sound quality) if the charge level is below 20%. To avoid this, keep the charge above 30% or turn off optimization in the Mi Earphones app.

For better sound, always use an AAC or aptX codec (if supported). SBC gives noticeably worse quality, especially at high frequencies.
6. Alternative ways to connect (if Bluetooth does not work)
If Bluetooth on Redmi Note 7 completely failed (for example, after updating the firmware), there are workarounds:
- π Bluetooth Adapter: Connect an External Bluetooth Adapter via USB-C (For example, Avantek USB Bluetooth 5.0. The phone recognizes it as a normal device, and you can connect the headphones through it.
- π‘ FM-Transmitter: For old headphones with FM-The receiver (e.g., some Sony models) can be used by the user. FM-A transmitter connected to the phone's audio output, but the sound quality will be worse than Bluetooth.
- π΅ Wired Connection: If your headphones support a 3.5mm connector (e.g. Bose QuietComfort 35) II), use the adapter USB-C β Note: Redmi Note 7 does not have a built-in DAC, so the sound will be of medium quality.
If the problem is a Bluetooth software failure, try resetting your network settings:
Settings β System β Additional β Resetting β Resetting Wi-Fi, mobile network and Bluetoothβ οΈ Note: After resetting the network settings, all stored Wi-Fi passwords and associated Bluetooth devices will be deleted.
