• 📞 When you call actively, the sound will automatically switch to the headphones (if they support the profile). HFP).
• 🔋 The simultaneous operation of two devices increases the battery consumption ~10–15%.

Lag is a common problem when using wireless headphones in games or when watching videos. On the Poco X3 Pro, this can be partially fixed:

• 🎮 For games: Use headphones with support for aptX Low Latency (for example, Audio-Technica) ATH-CKR7TW). Enable game mode in Bluetooth settings (if available for your model). Close background apps that use audio (such as YouTube Music or Spotify).
• 🎥 For video: In the player (for example, VLC or MX Player) increase the audio buffer by 100-200 ms. Turn off audio processing in the headphone settings (for example, DSEE Extreme at Sony Headphone Connect).

If latency is critical (like in shooters like PUBG Mobile), consider using a Bluetooth adapter with aptX LL (like Creative BT-W5) that connects to your phone via USB-C and provides a latency of less than 40ms.

💡

The best combination for Poco X3 Pro games is headphones with aptX Low Latency + power saving mode, in which case the sound delay is reduced to 60-80 ms, which is acceptable for most genres.
