Ugreen Transmitter Audio Adapter

With this device, you can wirelessly stream audio from non-Bluetooth sources such as in-flight entertainment systems, televisions, or treadmills to your Bluetooth headphones or AirPods. It supports dual pairing, allowing two headphones to receive audio simultaneously. Fully charge the transmitter before first use. Connect the included USB-C charging cable to the USB-C charging port of the device and a USB power source. The battery indicator LEDs show the charging status and turn off once the battery is fully charged. A full charge provides up to 19 hours of battery life. Plug the transmitter's built-in 3.5mm jack into the audio output of your desired device. For in-flight entertainment systems with two 3.5mm jacks, use the included dual 3.5mm AUX adapter. For single 3.5mm jacks, plug the transmitter's 3.5mm jack directly into the audio port of televisions, computers, or treadmills. For dual 3.5mm jacks (airplanes), connect the dual 3.5mm AUX adapter to the transmitter's 3.5mm jack and then plug the adapter into the airplane's audio ports.
