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.

Hooked up to my computer to play music throughout the house, originally I was debating on just hard wiring everything... but, sense the two are bluetooth, I wanted to try to use something like this. Line out from the laptop into the "Aux TX Input" and got it linked the STR-DH190 and Vizio S2121w - both play without the echo gap that the samsung s21 ultra was doing. The volume on the transmitter works well on the Sony but not the Vizio (Soundbar), the pause/play (mute) button works well. I would treat it more as a ronco item, set it and forget it. Once things have been paired and set up, the next time you turn everything on, it reconnects faster and easier then the initial launch. If your casting bluetooth music to multiple rooms, give it a go. It works well, and the quality/ distance is decent. (in my case, the Sony is only 4.2 so I can't judge the newer BT levels for quality, it is not the transmitter holding it back, but the receiver.)

This item worked well UNTIL there was a sudden loss of house power. When it returned, the device wouldn't transmit audio

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.

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'm using this for an iPod station, so to speak. I have the 3.5 jack plugged in directly in the middle of the house for the purpose of using two different bluetooth speakers, one outside and one inside. The range is about what you'd expect. I can get about 15-20 feet away using a speaker outside before it starts stuttering. Inside is fine, but the big setback for me was the fact the volumes do not act independently from one another. If I turn up the speaker outside, the speaker on the inside also turns up and vice versa. Which is the big negative for me, since I wanted them to function on their own. Also, if you disconnect one of the speakers, it does pause the other connection. Meaning, I have to go and reconnect it from the transmitter before I can hear the music again. ALSO, the sound coming from both speakers (both the same model and brand) is NOT in sync. So if the speakers are near each other there is an echo effect. Until we can get that Stark tech where you just walk into a room and the music follows you around, this will have to hold me over.

This honestly works just as well as the very expensive devices. I originally bought an expensive one from a physical store, and then bought this one to test and this was identical to the expensive one. I ended up returning that one and keeping this one because it was such a cheap price. I am currently using this on my turntable and it connects to my speakers instantly. The volume control on it is useful and is easy to use!

This is great! I have a 2008 SONY Bravia 42" tv, so not Bluetooth ready. This changed that! East to hook up, I used the optical cable and get awesome stereo sound with a pair of 20 year old Bluetooth Jaybird sports ear buds and my single ear Plantronics Bluetooth for my phone. I have ordered a set of Bluetooth earphones as I like this set up so much. I find the range of reception to be decent around my house and down my driveway to the mail box. I enjoy listening to my YouTube podcasts and movies while I cook. Lag time for watching tv is not noticible. I haven't tried to cast it to my Bluetooth receiver to play in surround sound yet, but I'm sure it will be great. I'm 70 years old, not tech savvy but found this so easy to set up.

Does what is says on the box. But it really should come with its own charger.

I have only had this transmitter for a few days but my first impressions are very good. It connects easily, has a good range, sounds good, and I cannot find any fault worth mentioning. Would buy again.
