Connecting wireless headphones to Xiaomi Redmi Note 7 via Bluetooth: the full guide

Why Redmi Note 7 doesn’t see headphones and how to fix it

Wireless headphones have become an integral part of everyday life – they are convenient for sports, work and listening to music without entangled wires. However, owners of the Xiaomi Redmi Note 7 sometimes face problems when connecting for the first time: the phone does not find the device, the connection is interrupted or the sound is distorted. In this article, we will discuss not only the standard pairing procedure, but also the hidden settings of MIUI that will help stabilize the connection.

The Redmi Note 7 (codenamed lavender) features a Qualcomm Snapdragon 660 chip that supports Bluetooth 5.0 with improved range and data speed. However, even with a modern module, users are faced with nuances: for example, AirDots or Sony WH-1000XM3 headphones can connect not the first time due to the conflict of A2DP (for streaming music) and HFP (for calls).

Preparing for connection: compatibility and charging check

Before pairing, make sure your headphones are Bluetooth 5.0 or earlier (4.2/4.1) compatible.Most models - from budget Redmi AirDots to premium Bose QuietComfort - support this standard, but there are exceptions. For example, the older JBL T450BT headphones (2017 release) only work with Bluetooth 4.1, which can cause connection problems with the Redmi Note 7.

The second critical point is the charging level, and if the headphones are under 15%, they may not be on the list of available devices.

  • 🔋 Look at the indicator on the headphone case (blinking red - discharged, blue - charged).
  • 📱 Some models (such as the Xiaomi FlipBuds Pro) have a voice alert about the battery level when turned on.
  • 🔌 Connect your headphones to the charger for 5-10 minutes if they don’t respond to the on button.

FAQ: Answers to Frequent Questions

Can I connect two sets of headphones to the Redmi Note 7 at the same time?
Yes, but with limitations. The phone supports multi-point (simultaneous connection to two devices), but only if the headphones support the A2DP Dual Link profile. For example, the Sony WH-1000XM4 or JBL Live 660NC can work in tandem with another device, but the sound will only play on one of them.
Why are the headphones connected, but the sound is delayed (lag)?
Sound latency is for Bluetooth devices, especially when watching videos. Reasons: Use the SBC codec (the slowest one). Switch to AAC or aptX Low Latency in the developer settings. Power saving mode is enabled. Turn it off in Settings → Battery → Power Saving Mode. The app (like YouTube) uses its own buffering. Try VLC Player, which allows you to adjust the synchronization of sound.
How to check the Bluetooth version on Redmi Note 7?
Go to Settings → About Phone → MIUI Version and click on the Version of the Kernel several times until the Equipment Test menu appears. There will be a Bluetooth item indicating the version (for example, 5.0). Alternatively, install the AIDA64 app from Google Play - it will show detailed information about the module.
Can I use headphones as a headset for calls?
Yes, but the microphone quality depends on the headphone model. For calls, the phone automatically switches to the HFP (Hands-Free Profile) profile. If the person is not listening to you, check that the headphone microphone is not closed (for example, AirPods have microphones located on the "legs"). Turn off noise cancellation in the headphone settings (if any). In Settings → Sound → Sound quality, turn on the voice improvement option.
What if the headphones are connected, but discharge quickly?
The quick headphone discharge when connected to the Redmi Note 7 can be related to: Unoptimized codec. Try switching from aptX to AAC. Permanent Bluetooth scanning. Turn off automatic device search in settings. Background apps. Close applications that can use the headphone microphone (such as voice assistants). Also check the battery status of the headphones — if they are old, the capacity could be significantly reduced.
