Bluetooth Receiver for Car, Noise Cancelling 3.5mm AUX Bluetooth Car Adapter, Wireless Audio Receiver Transmitter for Home Stereo/Wired Headphones Airplane, Gold

This 2-in-1 Bluetooth 5.3 adapter serves as both a transmitter and receiver. In TX mode, it transmits audio from a TV, computer, or in-flight entertainment system to your Bluetooth headphones, earbuds, or speakers via the 3.5mm aux port. In RX mode, it connects your smartphone to wired speakers or headphones wirelessly. It supports hands-free calling with CVC8.0 noise reduction and DSP technology, effectively minimizing echoes and background noise for clear calls. The built-in microphone and MFB button allow you to answer, redial, end, or reject calls. It offers up to 6 hours of usage for calls or music, with a full charge taking about 1.5 hours via the included Type-C cable. The flexible 3.5mm aux port design aids in protecting the device and facilitates use in tight spaces. It maintains a stable wireless connection up to 10 meters (approx. 33 feet), disconnecting automatically if the range is exceeded.
