UGREEN Bluetooth 5.1 Audio Receiver for HiFi With 3.5mm Aux and 2 RCA Ports, AptX HD, Noise Canceling, Dual Pairing, Long-Range Stereo Adapter for Smartphone, PC and More

like all UGreen products, it is just unpack, connect and go. This is not an exception.works out of the box, without a lot of fuss and the battery last forever. Specs mention 8hours but ihave been using it for a full weekend without a beep and I have only heard the "battery is low" voice message (yes, it announces low battery!) only once after heavy usage.Pairs with Mac, Linux laptops and iPhon and Android phone with 0 effort. The sound quality is excellent and really crisp (not some muffled, buzzing, or distorted sound as it comes out of a tin).It is an excellent addition for your old HI-FI that has no BT and easy to stream music in seconds.Saved me from running cables. Highly recommended.

This product is awesome, I use this product to make my amplifier have a Bluetooth option and synch my phone to my amp. It allows a digital radio app and Amazon music to be used with my hifi.I use this music system in my gym whilst training. This product has saved a lot of space. Before buying this device, I was using a hifi separate tuner, cd player, a cassette deck, ipod & the amp. Now this has been reduced to the blutooth device and ipod. The sound is really good and works exceptionally well.My system is a Samsung S7 edge, ipod, Naim nait 3 amp & Ruark Icon speakers.The sound from this little device is so good I am going to get one for my main audio system which comprises of Linn Audio and Naim Audio. I am not listing my systems to show off, I am letting you know how well this little device works. The only thing i would say is use the phono sockets on the device I thought it sounded better than the 3.5mm jack, although it was not bad, even when using a better third party cable. The phono did sound better.It is a small and very well made product. Hope you enjoy it as much as I do, very surprised at the sound for the cost.

It sends the audio to the RCA outputs and the 3.5mm output at the same time. So you can feed two devices simultaneously. For a teenage party, I did this to send the music to two different rooms at the same time. There was a stereo in each room. The unit was in the middle. I used long cables to feed each stereo. People could move between the rooms and the music was in synch. It worked well.There were no lost connections or interference all night. I didn't choose it or test it for sound quality, but it sounded OK and we got good volume without distortion.The only niggle is that the user interface is unintuitive. There is only one button and an two-colour led. The instructions explain different types of button presses for each function (eg on, off, pair) and the led patterns that tell you what's happening. On a light read, these weren't too clear. Looking at it, it's hard to see if it's in or off. But these are not big points.

I bought this device to connect my 11 year old Marantz M-CR610 to Bluetooth giving access to Amazon Prime music. It was easy to set up and the sound quality is up to the standard I'm used to playing FLAC files from a large flash drive, or CDs.I can also easily play music files stored on my phone, and play BBC Sounds. Great product.One thing to beware of is that the output to the amplifier is lower than the other internal sources. This means that the volume on my Marantz has to be turned up higher. This is not a problem as there is plenty of power in reserve , but if you forget to turn it down when switching inputs you get a shockingly loud startup!

Bought this product to add Bluetooth connectivity to my retro CD system so that I could stream from Spotify on my phone. The stereo is over 20 years old, so the benefit of this particular item in having RCA AUX input was perfect for my needs. Connected without issue, responds to volume changes instantly and quality seems good enough through a 50w amp running through floorstanding speakers. Definitely a neat and simple solution to modern music on an old system. At an estimate, I've been circa 15m from the music player and it didn't drop signal, but this was only for 30-60 seconds.

Looks great, professional and good build quality but the charger and adaptor cables were missing.And it doesn't have a battery so it has to be permanently powered.If that wasn't bad enough the thing sounds like the "top end" is missing despite UGreen claiming it can go all the way to 20Khz - which is usually the -3dB point and most of us can't get close after our 20s.But even at my age and with hearing problems like Beethoven (who knew?) I can't hear the brighter audio. Sound from the TV was flat and uninteresting (vs. the internal speakers which produce a respectable range (Dolby Atmos my foot, Panasonic). Similar story on the Steam Deck. Paired without a problem but the audio was flat, lacked bass and high-frequency information. And this is into some BeyerDyanmic 990s (superb cans, available from Amazon which is where I got mine). The Beyers produce excellent detailed audio even with HRTF 5.1, 7.1 and 9.1 sources which is what attracted me to them.If I had the time I'd run a full sweep to see what the thing is actually capable of but I'm going to have to return it and replace it with something that does work. Low latency is great and all, but the amplifier (presumably a Class D SOC) lacks detail and sounds muddy. Sorry Amazon, this one is not what I expected.

The volume output is low requiring you to turn up the volume (usually to full) of whatever it's connected to. If you use your amplifier/speakers for anything else, you'll get blasted if you forget to turn the volume back down again.It'll disconnect when idle, so you'll need to reconnect whenever you use it again.That said, when it's actually playing it works fine.

Great item easy to install, small enough to hide behind HiFi. Fitted using RCA cable and very pleased with sound quality.
