⚠️ Important Notice: Audio Receiver Function & Connection Modes

1. Bluetooth Audio Receiver Only (RX): This device functions strictly as a Bluetooth audio receiver, NOT a transmitter. It wirelessly receives audio from your Bluetooth devices (smartphones, tablets, laptops) and outputs sound to wired speakers, amplifiers, or car stereos. It cannot transmit audio from a PC, TV, or MP3 player to Bluetooth headphones or Bluetooth speakers.
2. Dual Playback Modes:
   • Mode 1 (Direct USB Audio): For speakers that feature a dedicated USB audio decoding port. Plug the adapter directly into the speaker USB port without an AUX cable.
   • Mode 2 (3.5mm AUX Audio): For standard speakers, soundbars, amplifiers, and car stereos. Plug the adapter into any standard USB port for 5V power, and connect the included 3.5mm audio cable between the adapter and your speaker's AUX IN jack.
3. Car Stereo Connection Requirement: Most vehicle USB ports only support USB flash drive storage or charging, not USB audio decoding. For car use, always connect via the included 3.5mm AUX cable to your car AUX IN port while utilizing the USB port for 5V power.
4. Music Streaming Only: This adapter is designed exclusively for wireless music and audio playback; it does not feature an integrated microphone and does not support hands-free phone calls.
