USB Bluetooth Transmitter Receiver 2 in 1, Bluetooth Adapter for TV PC Headphones Home Stereo Car, Wireless Audio Adapter with 3.5mm AUX

Very simple and intuitive to use.I just received mine and tested it on both my TV and car USB ports.I was initially concerned the behind-the-TV USB port wouldn't output enough power to get it to work (not enough juice to power my firestick) but it worked just fine. There's a little latency in the connection you'll notice a slight delay from the bluetooth connection when you compare to the television speaker output, but it's hardly noticable if you stick to just bluetooth output.I mainly bought it for my car as i have a 3.5mm aux input but no working bluetooth for media; until now. It works perfectly. It's simple and to the point with a low profile.Also it's a very minimal interface (a single light will appear either red or blue depending if it's recieving a sound via bluetooth outputting to 3.5mm speakers - blue or if if it's transmitting a signal from 3.5mm jack to transmit to a bluetooth device like wireless buds or bluetooth speaker).Works for my needs and it's inexpensive but very effective. I'm pretty pleased so far. Ten bucks well spent.

I had to fly for business this weekend on Delta. Plugged this into their entertainment system (USB and headphone jack), pressed the button on the back of my Airpods Pro case, it connected in about 15 seconds and worked great on both flights. There is a slight lag in the audio (which is why I gave 4 stars instead of 5) but aside from that I had no complaints.

I wanted to use my bluetooth headphones to watch TV and the description sounded like it would work. My Visio TV has a USB port but no 3.5mm jack. I tried to use RCA connection with 3.5mm jack adaptor, but it would NOT work. I could see the red light for TX pairing change from blinking to solid and hear pairing sound on headphone, but there was no sound.

This product user interface can't get any simpler. And the USB device is not much bigger than a USB-A plug, so it fits nicely behind my TV. Love it!But, there is one small problem. While it does receive full two-channel stereo perfectly, the one I received doesn't TRANSMIT full two-channel STEREO. It transmits two-channel MONO. Possibly a defective product. I'm working with the sell to address this issue. I'd love to update this to 5 stars. :-)

The description for this product said "Charge it on the USB port and connect it to the device via the audio adapter" which lead me to believe that is was rechargeable. It is not. It works well when plugged into a power source but is useless for jogging, biking, mowing, etc. which is why I bought it.

This little device allows bluetooth Speakers on any device with a few tricks. First you will need an AC adapter to 5 volt to power this device. You TV requires an earphone jack. That's it. Plug your adapter into an AC. Plug this into the 5 volt power until the led is red. If it is blue remove from power and plug in again. It should now be red. Plug you earphone cable into the earphone jack on your T.V. Turn on wireless speaker and wait for it to connect to TV All done. Do not use usb jack on tv as It may or may not work that way.

I like to use a Cown Plenue as my music player. This is a wired only device. That's okay, I still have wired headphones. Just occasionally, however, I need to have my Cowon talk to a bluetooth device. The answer is simple: this thing. It plugs into the 3.5mm jack on my Cowon and talks to a bluetooth device. Brilliant. It's simple and easy to use. It sometimes takes a couple of attempts to get it to swap from receiver to transmitter but the indication is clear regarding which mode you're in. Highly recommended.
