Add Bluetooth functionality to your old-school stereo, TV, or PC with this compact 2-in-1 Bluetooth audio adapter. It works as both a transmitter (TX mode) to stream audio from non-Bluetooth devices to Bluetooth headphones or speakers, and a receiver (RX mode) to bring wireless streaming to older stereos or car audio systems. Powered via USB (no internal battery), it?s easy to set up and keeps going as long as it?s plugged in. Includes a 3.5mm AUX cable and supports hands-free calls with a built-in mic when in receiver mode. Great for personal TV watching, streaming playlists, or making calls on the go. While it claims to have a ?display,? there?s actually just a small indicator light?so don?t expect anything fancy. Lightweight and portable, it?s a handy tool if you need basic Bluetooth support without breaking the bank.
