Connecting headphones is half the battle. To get the best audio quality, you need to adjust a few settings on the Redmi Note, especially for models with Hi-Res Audio support (for example, the Redmi Note 11 Pro+ 5G or Note 12 Pro Speed).

Bluetooth codecs and their impact on sound:

• 🎵 SBC — Basic codec, supported by all devices, but with mediocre quality.
• 🎵 AAC — Best for music, supported by AirPods and most Xiaomi headphones.
• 🎵 aptX/aptX HD — High quality, but requires support from both devices (e.g. Redmi Buds) 4 Pro + Redmi Note 12 Pro+).
• 🎵 LDAC — Best codec for audiophiles, but consumes more energy.

One of the main problems with wireless headphones is the charge consumption of the phone. Bluetooth module, especially in aptX or LDAC mode, can significantly reduce the autonomy of the Redmi Note.

• 🔋 Turn off Bluetooth when not in use: Even in the background, the module consumes up to 5-10% of the charge in 8 hours.
• 🎧 Use the codec. SBC or AAC: It is less energy efficient than AptX or LDAC.
• 📵 Deactivate Device Search: In Bluetooth settings, turn off the “Visibility for All” option if you don’t need it.
• 🔄 Update the headphone firmware: Manufacturers regularly release power-optimizing updates (e.g. for Redmi Buds 4 via the Mi Earphones app).

6. Connecting headphones to multiple devices (multipoint)

Many modern headphones (such as the Xiaomi Buds 4 Pro or Sony WH-1000XM4) support multipoint, which is a simultaneous connection to two devices (for example, a phone and a laptop). However, on the Redmi Note, this feature does not always work stable.

2. Connect them to a second device (for example, a laptop).
3. On Redmi Note, go to Bluetooth settings, tap the headphones and select Connect to another device (if you have an option).
4. The headphones will now automatically switch between devices depending on the active sound source.

Possible problems and solutions:

• 🔄 Headphones do not switch automatically: Manually turn off Bluetooth on one of the devices.
• 🎵 The sound goes to only one device: Check if your model supports Multipoint headphones (the information is in the specs).
