RIOUSV Bluetooth Transmitter Receiver, 4-in-1 Bluetooth 5.0 Visible Wireless Bluetooth Adapter with Display Screen, Low Latency Audio Adapter for TV/PC/Car/Home/Stereo System

It has no problem connecting to several of my devices as a receiver, but only connected to one device as a transmitter, and refused to connect to several others. When I pressed the > button, my speaker showed in the screen, but it would not connect. No contact information was provided anywhere, so I have no recourse but to figure it out or send it back.

I bought this to receive audio from my FireTV to the amplifier but theres a very silly feature that auto shuts off the device even when its plugged in which means you have to manually turn it back on every single time. Theres no way to disable it either so Im guessing they expected this to only be used as a portable device but seriously a big miss.

I bought it to listen to my outdoor TV with a BT speaker from further away. I need to turn it on every time I want to use it even though its plugged into the TV USB. The audio lag is so bad I would say its unusable.

Great Product! Easy to set up(quick pair). produce clear stereo sound! Battery last long. recommending!

Worked flawlessly.

Very pleased with this bluetooth transmitter/receiver. Does everything I wanted it to do and more!!

great bro i like it. but there is some delay if you want to play game and etc... if you fire the gun you will here after 1 or 2 seconds later. For music purpose no problem at all.

I had high hopes for this. It has great features, transmit and receive, the display. My gripe is that in receiver mode there was almost no bass. I got it primarily for the purpose of driving headphones / in ear monitors. I not sure if others found this but it was like listening to a cheap radio from the 70s.

I like the quality of the sound and fast charging. Volume control works well and I can use the product during the charge without too much issue.

Literally spent like an hour trying every combination of buttons to get this connected to my headphones. I was able to see the headphones as a output source but it just would not connect. I have an older bluetooth transciever that connected right away. I was able to connect this unit to my bluetooth speakers and it was automatic and flawless. From a cosmetic standpoint the plastic case seems very thin plastic and for a $30 unit I was expecting more quality.
