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

This is rather clunky to carry around, but its fine.

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

I bought this RX/TX specifically for the display so I could see if it was on and functioning in the proper mode. Unfortunately, less than 2 months after purchase the display doesnt display. I liked it until it stopped displaying. The Amazon support is not good. It would be nice if the seller/maker would have some contact avenue, but nope.

Would not even enter transmitter pairing mode. Instructions and device did not match up

I have a pair of Pyle BT speakers that it would not connect to.

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.

Attached to TV, red light illuminated, turned on as per directions and NO screen. Probably just a bad unit, but will be looking for another brand.

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.

Two weeks ago II bought a RIOUSV BT-11 Bluetooth Transmitter Receiver for use with a Yamaha electric piano. I wanted to be able to practice late at night without disturbing others, and without having to deal with wires running from piano to headphones. The product descriptions for this and other such bluetooth transmitters claim that they have low latency, but I have yet to see any that actually state what the latencies are for their products. The BT-11 turns out to have a latency of about half a second (500 milliseconds)! To call this low latency is absurd. 40 milliseconds would be considered barely acceptable latency for use in gaming, music performance, and other such applications. 25 milliseconds would be considered good. 1 millisecond would be truly low latency. This products high latency makes it completely useless for the purpose I bought it for. The problem now is to find a transmitter that really does have low latency — from an industry in which all of the manufacturers seem determined to mislead the buyers.

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.
