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

Easy to use installed on my old stereo receiver found plugging it into the cd slot on the back of the receiver had the best sound quality. My phones Bluetooth was able to stay connected thur out the house

Works great. Has a long range output transmission. I highly recommend this product

I have changed my rating from one to four stars.I had returned the device because of the following problem:I ran it in TX mode, optical cable from my Sony TV, connected to my bluetooth hearings aids.It never reconnected automatically if it is disconnected.It didn’t matter if it was because I turned off the TV; or the hearings connected to the phone to receive a call; or I moved out of the device's bluetooth range. I had to put the hearing aids back into pairing mode (i.e. turn it off and on again) and set the device to search mode and reconnect.The vendor contacted me and suggested that the device may have been defective.He appealed to me to try a new device at no cost.I received the new device in three days.The new device works (almost) perfectly.It connects easily and, unlike the one I returned, re-connects immediately.However, if the receiving device (in this case my hearing aids) connects to a different Bluetooth device (say I receive a call on my phone which is paired with my hearing aids) it does not re-connect. You do not have to re-pair the devices, just push the knob once.Except for this small problem, I would give it five stars based on ease of use, quality of sound, and excellent customer service (which is definitely five stars!)

Good unit works as stated

La transmisión tiene un retardo de unos 500 ms, que dependiendo de para qué lo usea es un problema gigante, yo pensaba usarlo para conectar micrófonos y transmitir por bluetooth a un parlante, pero definitivamente no sirve para eso, voy a conservarlo a ver si en algún momento lo necesito, pero si alguien necesita esto para transmitir en tiempo real sin pérdida, no lo recomiendo.

Sound quality was good. The setup instructions were horrible but I figured it out and was able to set it up correctly. For me the latency was a deal breaker. The way to pass through optical from TV out to optical in on our sound bar is to use what they call bypass mode. Use the mode select button to go to tx mode to pair Bluetooth headphones. You can't do both bypass optical out to optical in and listen through Bluetooth earbuds at the same time. It is either bypass mode or Bluetooth mode, not both. Anyway, the latency in bypass mode, where it is just passing optical out through to optical in, on our sound bar is so bad it looks like you are watching a foreign film where the English translation is dubbed in while the lips are moving so off the soundtrack that it looks like they are speaking in another language. For people who don't pay much attention to that sort of thing these would be great. It found my earbuds with no problem after it was powered down, even unplugged, and powered back up. It remembered the pairing without issue. But the latency was too much for me. I returned this and bought an optical splitter on Amazon that splits one in into three outs. It worked great passing through optical from of the outs of the splitter to our sound bar and there is no noticeable latency. I connected another optical cable out of the splitter to a different Bluetooth Adapter, bought on Amazon, and there was a minor amount of latency going to my Bluetooth earbuds but that adapter has aptX capability and my earbuds are a little older. But even then the latency is tolerable. I found some inexpensive earbuds on Amazon and have ordered them to try with this setup. Also with this new two piece setup (splitter and adapter) I can listen through the earbuds and the sound bar at the same time. You can turn off the sound bar and listen through the earbuds alone or vice versa without the need to get up and click a mode button. Back to this device now. If you don't care about latency I have to say this did work really well. But I couldn't deal with the latency. I was surprised to see such latency in optical to optical bypass mode. I would have thought that would be latency free as it is with the splitter I ended up using. I pretty much expected to see some latency in Bluetooth mode. But I have to say that the latency in Bluetooth mode was a lot worse with this Bluetooth Transmitter Receiver than with the Wireless Bluetooth Adapter I ended up with. The setup I ended up with (not this device) is more convenient to use (I don't have to get up and press a mode button to switch between devices). But more importantly there is no latency using optical to our sound bar and there is a small (tolerable) amount of latency using Bluetooth earbuds.

Works extremely well

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.
