These work great for connecting my various audio/video receivers throughout the house! My main video receiver is a 4-zone Yamaha where I connected the transmitter to the Zone 2 Pre-amp output. This is in the basement inside a wall cabinet where I put the transmitter also. In my office, I've got a 1980 Yamaha stereo amplifier and one of the receivers. I connected one of the receivers to the Aux 1 input. I've got a Sony A/V receiver in the living room with another TV connected to it. I connected the other receiver to the Tape 1 input. Any input I choose on Zone 2 of the Yamaha is now transmitted wirelessly to the other two. I can adjust the volume of the remote systems either manually at the volume dial for each or by using the Yamaha app and changing the output volume of Zone 2. The sound quality is excellent, and I've not had any dropout problems. I highly recommend this setup for similar applications. I can now listen to my Spotify playlists on the old 1980 stereo system! The kit comes with 1 transmitter, 2 receivers, 3 power bricks, 3 USB A to USB C cable for the power. Also included are 3 optical cables, 3 mini to mini cables, and 3 mini to stereo phono cables. So no matter what combination of connections you need, this kit has you covered. For my application, I used the 3 mini to phono cables. The pairing between the transmitter and receivers is fast and automatic. There is a manual override to retry the pairing if there is a problem, but I have not needed to use that. I highly recommend this for audiophiles.

Works great, both receivers connected right away. I installed the transmitter on zone 2 on my stereo. One receiver connected to Klipsch R-51PM speakers in my in the next room. Second receiver connected to my basement sound system so I can now have the same music throughout the house. I give the manual 2 stars though. It's one that has 8 languages on a page for each step. Does not tell you what a flashing red light means. (not connected to a receiver)

Absolute garbage, returned them. Very loud buzzing sound when plugged in to subs. Other transmitter I had didn’t do it and we tried 3 different RCA cables that weren’t by anything and were braided and in wall rated. Don’t buy.

Pros *Easy to setup, plug and play. , if it doesn't work out either receiver/transmitter off and on. And it should, connect almost instantly (solid blue led mn both devices) *Well constructed, all metal casing and came with all the wires you need. Including TOSLINKS. *No latency issues, I have not (2 subs in use) had one issue connectivity wise. Cons *Only one really, the output signal towards the receivers seems very low. I had I up my subwoofer channel significantly. To get to the thx reference level I had before using the transmitter/receiver combo. That's the only gripe I have, it's a very good solid product for the money spend. I hope they last. Relatively, small and super easy to get it to work. And it does as advertised..

It transmits audio fine, but there is a slight hiss in the background of the receivers. If used for low volume background music, it's fine. That's what I'm using them for so I kept them. But for high volume serious listening, you'll need to spend much more money on a higher quality system.

Works beyond expectations! Removed all my cords and went wireless, not only great performance but also a great look!

I ordered this to drive 2 powered subs in my theater. I used the RCA connectors for both the transmitter and receivers. They paired with no issue but only static came out. I thought I had a defective unit so I ordered a replacement which arrived the next day and I got the same results, only static. I had read the instructions and they didn’t provide any guidance on which of the 3 provided cables to use: RCA, 3.5mm and optical. I tried the 3.5mm cables on both the transmitter and receivers and they worked. Can’t say I was thrilled about the hassle but I am happy with the product.

I had no problems connecting the transmitter to the 2 receivers. The sound quality is amazing. It is that compared to a wired connection, even through several walls and over long distances. My only wish is that Amazon let's this manufacturer sell additional receivers or offer them along with the transmitter, like one transmitter and 4 receivers, not just 2 receivers.
