It works properly once connected, the fact that every time it disconnects you have to take it out and plug it back in to reconnect is ridiculous!!!

It has RCA connection and optical fiber. The bad thing is that it doesn't connect to the laptop, and it is cumbersome in its settings.. it also transmits sound at a much lower level. I do not recommend it for serious use.

It works just fine as long as you don't move your phone to another room from the receiver. It picks up the signal directly, something perhaps unexpected, but I only turn on the receiver when I want to use it

While it has relatively good performance, it tends to shut down relatively quickly so it needs to be charged again!

It is not available for connection unless you press the button, it goes into some kind of standby mode from which it does not come out unless you press the button. I have connected it to the TV to send sound to the stereo and every time I have to press the button on the receiver to connect. On the positive side, it always connects if I do that. And I have no complaints about the sound, it's great.

It does its job perfectly fine! I have connected it to a Sony amplifier that was purchased in 2002, and now I can play from all Bluetooth devices such as phones, tablets, etc.
The sound quality is excellent! It brings back to life old stereo systems from previous technology!

3 stars because if it stays open for a long time without any device on it, then you have to press the button continuously to connect a device, which makes it impractical. 3 stars graciously due to the good sound.

Very good product. UGreen has good build quality in everything it sells. Very easy to install. You need to have a USB charger. It has a battery that, as it says, lasts up to 8 hours. I haven't measured it, but it's very convenient. The phone connected quickly and instantly. It says it's for 10 meters, but it works a little further (13m to be exact). Very small, you can easily hide it behind the amplifier or next to it. The sound quality is good. I can't judge in detail because so far I have connected it to a 2000s old stereo amplifier. I highly recommend it.

Update: When it is permanently connected to speakers, for example computer speakers, and they are turned on without playing music from Bluetooth, they make a small, annoying noise.

It works great and upgrades old sound systems. I paired it with a Yamaha AV405 and the flexibility it added is remarkable

Honest and decent for its price.
Helps to operate vintage stereo.
I would buy another one if needed.

Amazing gadget, both electric and battery-powered. Its battery lasts around 5-5 1/2 hours on full charge. For its price.., excellent!!!

The blue tooth connects quickly and easily. I have it with RCA to a 78 amplifier and it performs excellently.

31/10/22 still works perfectly. even after a lot of use. Very good for its price.
21/2/23 still works perfectly even with a lot of use. It immediately finds all devices.
