Aluratek ABC53F Bluetooth Audio Receiver and Transmitter with Bluetooth 5 (Stream up to 300 feet), AUX, RCA and Optical Connections Supported, Low Latency, aptX, Wireless Audio TV to Headphones

Sounds good. Good audio separation, Bluetooth range and built in battery was a nice surprise. I’ve only send audio to via Bluetooth so I don’t know the other function works. But I use it all the time. I specifically use it at work, because internet sucks for and I can use my phone away from the speaker system where there is no reception to another part of of the building where I get reception to so I can stream music off Spotify. I can also hand the phone to customers and also with private parties the costumers can link there own devices up. Helps with the atmosphere with out having to run back to a Corner to change the music like how you would with aux.Although the things in this review aren’t specific to this product alone. I’m sure there are other ones. But, to my knowledge this was the best of everything for a good price… and if not oh well..It’s been vary vary worth it for me.

The device is transmitting BT as advertised, but I can't vouch for the claimed "up to 300 feet" distance, which is how I justified the premium price. While I have it transmitting from under a sub floor and tiles, I had drop outs until I moved it nearly under the receiving speaker, which amounted to about a 25' distance, with the single floor barrier, before it remained steadily paired. I liked the fact that it had RCA inputs, as those tend to hold on better than 3.5mm, (which it also has), but it could also benefit from more indicator lights as it only has the one tiny pilot light to indicate power, charging and pairing status.

Connection is easy and sound is very good and it allowed me to use a very good but older receiver and excellent speaker system to stream music from my phone.

This item connected fine in both TX / RX modes and would be fine if it didn't need to sync up with another Audio or Video source. I found it to have a 2 to 3 second delay between devices that would not work for my purposes.

Works great. A little tricky to figure out at first but connected 2 headphones without a problem. Nice to use the headphones of my choice.

Worked great for 2 weeks then stopped working. Tried to return but they don’t stand behind their product. To bad!

This product has worked great and flawlessly for me so far. I have not tested the Max diff distance however I have seen it go about 70' to 90' through 2 doors and on the outside of my apartment, and it works with no latency and no breaks in signal.I highly recommend this product. Also, you can connect to receivers to one transmitter.

I used it to stream music from my phone to my stereo. This is the second one I have bought and they both work well. I highly recommend it.
