Bluetooth Transmitter Receiver 3-in-1 Bluetooth 5.0 Audio Adapter for 2 Headphones With Bypass Volume Control Low Latency Long Range LCD Display ON/OFF Optical AUX RCA for TV Home Stereo Speaker

I purchased this Bluetooth Transmitter Receiver to provide connection for my Bluetooth headphones to an old Toshiba HDTV that has no wire audio cable output connector, but which does have a fiber optic cable audio output. I connected the Transmitter Receiver to the TV using the fiber optic cable.I use a USB C to USB A cable, with an inexpensive 120V AC to 5V DC power adapter to power the device.Following the installation and use instructions, my Lenovo Bluetooth headphones pair up with the Bluetooth Transmitter fairly quickly. The display on the device is easy to see, and it helps greatly in the pairing function. I am then able to mute the TV speakers volume or set it to whatever level other viewers may desire, and I can adjust the TV volume on my headphones to my needs.I have used the headphones connected to the TV via the Bluetooth Transmitter, and I have walked into other rooms in our residence, up to 30 feet away, with three walls between the transmitter and the headphones. The connection remains solid, and the sound quality is unaffected under those conditions.When viewing various programs, usually sporting events or news broadcasts, I do not notice any distracting lag between the sound and the picture on the TV. I have not tried simultaneously pairing more than one device to the transmitter, so I can't report on that capability.Overall, I am very pleased with the quality and function of this Bluetooth Receiver Transmitter. It seems to be very well built, with high quality components, and I would certainly recommend it.

Added comment:I have been using this for a week. I bought 2 other devices before this, that just didn’t work. Bought another model of one of the manufacturers, more expensive, also didn’t work. Had to return for replacement one of the others, because it came used.I just put in an order for a second one of these. They work! I am using it to use headphones and ear buds to watch tv. Simple use, but was having trouble finding a device.I totally endorse this one. Easy and reliable to use!I wanted to hook my tv with an optical cable to Bluetooth headsets. Should be easy. But I bought and returned 3 other models that just would not work.This one has a screen that shows what Bluetooth device it detects. Then a little fooling around and you are hooked up.Unlike other devices I returned, the sound is clear with no clicks or pops.Plus the price is right!

I use this so I can hear the TV at normal levels. Works well although there is a slight delay. The mouths don't line up with the sound. I just can't look to closely when I listen.

Took a few minutes to hookup and to learn how to use. After that, I haven't found anything Bluetooth that I use that won't connect. And it connects quickly. The distance is incredible to. Side note: I am hearing impaired and prefer assistance hearing tv. I use earbuds, bt speaker, headphones or my hearing aides (that connect to blue tooth). All connect. Highly recommend. I have so many options to hear the tv now and don't have to disturb my family, its wonderful. I need 2 more for other tv's will purchase in future.Update: purchased and received 2nd one. Recommend

The Transmitter worked well when finding and connecting from my Alesis QS8.1 synthesizer keyboard 'Headphone Jack Out' to my Bluetooth JBL Headphones. Worked like a champ. Very quick. The Sound quality was fine. I did notice a slight hum from the transmitter, at higher volumes, but I overcame that by turning the volume down on the transmitter and volume up on the synthesizer.Unfortunately, there was some initial latency between the devices when I begin pressing keys on the keyboard. Abut 1/25 of a second delay. When playing the piano, that is a killer. Playing requires instantaneous feedback. So I had to send it back.Even though I never tested any other transmitters, I would venture to say this issue might be an industry wide defect and not just with this product. I guess I will have to rely on wired headphones for the time being.Having said that, I am sure the transmitter works well with TV's and Stereo Music where the delay will not be easily noticeable.
