UGREEN Bluetooth 6.0 Receiver with LDAC Hi-Res Audio, Bluetooth Audio Adapter for Hi-Fi, 15H Playtime, Long Range, Dual Pairing, Wireless Adapter for Speakers/Home Stereo

U Green BT6 rx for hifi
It arrived next day, so it must have been warehoused in UK, and was a good price. It is quite small and light, looks well made and does what I wanted – that is to connect my iPhone 13 mini to my old Onkyo amplifier! I was hoping it might come with an RCA lead but it works ok with the 3.5mm jacks. I’m not good with tech and the coding so it is probably using the iPhone default system but it sounds a lot better than my old Sony Walkman from yesteryear. It was easy to set up, even for me, and I’m happy with the result.

Great sound and convenience but could do with more features.
This is a very basic looking unit. Has very little in the way of extras. No ‘move to the next track’ button, no volume button, no remote control, in fact its just a basic player with an on off switch which is tricky to use without deleting all the settings. (3 secs to switch off, 6 seconds to delete all information). Where it really does come into its own is its ability to transmit LDAC information to your hifi system and thus take full advantage of HI-RES music. I have a different make of unit (Bluetooth 5.4 Receiver for HiFi, Wireless Audio Adapter with AUX 3.5mm/RCA Bluetooth Audio Receiver for PC/Mac/Smartphone/Tablet/AV Receiver, AptX HD, Dual Pairing ) which has all the above functions and works well for less money, however this UGreen unit )is the only affordable unit which enables me to take advantage of the 24bit music catalogue that is offered on my Qobuz music streaming platform. I’ve bought a WiiM plus pro digital streamer to use to listen to Qobuz through my hifi system and its super but its over £200 (and worth it) . I wanted to be able to use my phone to stream to a second system in my mancave, which I can do with the cheaper unit but it can’t produce the hires that is so much better than the CD quality I have fallen in love with. There’s really nothing wrong with regular CD quality streaming but once you hear true 24bit or even 16bit transmission, the difference is clear. Anyway this unit is taking the place of the WiiM and working in 24bit and its £200 less expensive. By the way, your phone has to be able to be able to send LDAC to the box for it to work in Hi-res. If your phone won’t do it I wouldn’t bother and would go for the convenience of the cheaper units with volome controls, remotes and skip to next track. I would also say that I’m a nutter for hifi and regular CD quality might be more than enough for most people. Hope this hasn’t been too complex. Its potentially a great unit for sound quality (probably the best) at a tenth of the price of a WiiM which is also a bargain at £200 compared to other makes which can run into the £thousands. I’ve docked it a star purely because of the lack of features, sound quality (for the price) is everybit 5*

Excellent. Just works
Wanted to convert an old Arcam rCube to Bluetooth too connect to an echo show. Tried a few Bluetooth adapters. The echo is a little bit fussy but connected to this immediately. Sound quality excellent too. Very pleased

Great for music
Works very well. I would recommend it

Supports LDAC, which is why I bought it. Works great with Pixel 10 which also supports LDAC. I ran some frequency response measurements of this thing to see what the difference was between some of the different Bluetooth codecs. So this supports regular old-school SBC, Apple’s AAC and Sony’s LDAC up to 990 kbps. The main thing I was looking for was flatness across the 20-20,000 audio spectrum, low-end cut off and upper-frequency cutoff.The graph here shows one of each of the options above. The low-end cutoff was the same for all, with the response down -0.5 dB at 20 Hz. There was no difference for any of the codecs regardless of bit rate. The -3 dB point on the low-end was about 7 Hz for all. Nothing noteworthy here as that should be fine for just about any application. Where it gets interesting is the upper frequency cutoff, which is directly related to bitrate and codec. Not surprisingly, AAC limits to about 16.5 kHz (-3 dB point). This may or may not be audible for most people but does represent the lowest cutoff point of any of the codecs tested here.SBC actually looks better, providing full audio bandwidth all the way to 20.5 kHz.The lowest bitrate LDAC at 330 kbps tops out at ~18.1 kHz sitting right in the middle of the other two. This bitrate is a good comprise between connection quality and sound quality. They say that the higher the bitrate, the worse the connection quality could be, so if you want higher bitrates, keep the device close to your source. I have this thing in my car, so it’s usually within a foot of my phone. These measurements were done within a foot of the receiver, so I was not taking into consideration connection quality over long distances. LDAC has the option to change bitrate depending on the quality of the connection, so it will dynamically assign whatever bitrate it can get away with and still maintain a connection. I forced each of the bitrates shown here.Upping the bitrate to 660 kbps brings the usable audio spectrum all the way up to 30.1 kHz, well above the range of human hearing and certain in line with what is generally considered high resolution audio (basically would be 60 kHz sample rate stuff, not typical, but above 48 kHz).Setting to the max available bitrate of 990 kbps we see the final upper cutoff reach 48 kHz which is well inside the region of high res audio (represents 96 kHz sample rates). Basically should be indistinguishable from source material. Now this is only one piece of the audio puzzle, I did not do noise floor or distortion measurements. A lot of that is more dependent on the DAC internal to this unit and not a real function of the codec’s themselves.But overall, the UGREEN does an excellent job as a BT receiver and honestly I would use this in any of my higher end systems without question. I use it in my car and it beats the BT receiver built into my stereo by a small enough margin that I generally prefer listening to this over the car’s internal BT. It connects super quick and makes no annoying sounds other than the typical Bluetooth connected voice. The battery stays charged long enough, though I keep it basically plugged in all the time in my car via a regular 12V-5V USB adapter. The 1/8″ plug makes a direct connection to my AUX in port so it’s a pretty simple hookup. Price was just right too. I can’t actually comment on if it truly is BT 6.0. but everything I threw at it it worked perfectly. If you’ve got an iPhone, the AAC should work no problems, if you’ve got Android, the LDAC option is a great upgrade.
