⚠️ Important Notice: Dual Audio Sharing & Power Guidelines

1. Dual Audio Output: Both 3.5mm audio ports deliver simultaneous audio playback. When two pairs of headphones are connected, in-line volume control and microphone call functions operate on one primary connected headset.
2. Charging Port Functionality: The USB-C female port is dedicated solely to PD fast charging input (up to 60W, 20V/3A). It does not transfer data or support USB-C headphones.
3. Port Verification: Designed exclusively for host devices equipped with a functional USB-C audio-enabled port. Not compatible with Lightning or legacy interfaces.
