Many people mistakenly think that for good sound, just stick your headphones into the headphone jack or turn on Bluetooth, but in fact, the Redmi Note 8 Pro hides dozens of settings that affect the quality of playback. For example, few people know that this phone has a hardware amplifier that can be activated through an engineering menu. MIUI It only works with certain codecs, and we'll go through all the nuances, from choosing the right type of headphones to solving rare bugs like hissing in speakers.
If you use a 3.5mm wired headphone, youโll encounter one feature of the Redmi Note 8 Pro: the phone supports high-omb models (up to 300 Ohms), but by default limits output power. This is designed to protect the speakers, but prevents the premium headphones from unleashing their potential. Wireless models (especially with support) AAC or aptX) require separate configuration of Bluetooth codecs and profiles, which we will discuss below.

5.Use of USB-C headphones and adapters
Redmi Note 8 Pro does not have built-in support USB-C audio (unlike Xiaomiโs flagship models), but you can connect these headphones via an adapter:
How to connect USB-C headphones:

- Reboot the phone with the adapter connected.
The sound is distorted or interrupted:
- It could be because of a power shortage, try plugging the charger into the hub.
- Update the phone firmware โ in older versions MIUI were bugs with USB-audio.
The microphone is not working:
- Most of the time. USB-C Adapters are not supported by a microphone. Use Bluetooth or a standard 3.5mm connector for calls.
Important: Adapters without built-in DAC (digital-to-analog converter) will give a sound worse than a standard 3.5 mm connector. For high-quality audio, choose adapters with a chip, such as DragonFly or the original from Xiaomi.
