UGREEN Bluetooth 6.0 Receiver with LDAC, Hi-Res Wireless Audio Adapter with Low Latency, for Old Stereo/Speakers/Wired Speakers/Home Audio Music Streaming Stereo System

LDAC for the win with this one
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.

Killer sound, fast BT hookup, great product!
BT connects quickly. Stream never drops. With a Droid you can use LDAC and it sounds awesome! Highly recommended.

A must buy for older receivers without bluetooth!
Read This Before You Return It!If you’re having trouble connecting this Bluetooth adapter to your audio equipment—don’t give up yet! I almost shelved it thinking it was incompatible with my setup, but after a little help from ChatGPT, I got it working perfectly.Here’s what I learned:I wanted to connect the UGREEN Bluetooth 6.0 Adapter to my Yamaha RX-V677 receiver, and the key was using the right cables. You need a male-to-male RCA cable (red and white plugs) to connect the adapter to the Audio In ports on the back of your receiver. Make sure you’re plugging into just the red and white ports—not the yellow one, which is for video.Then, power the adapter by plugging the USB cable into any USB power source—many receivers have a USB port on the back, which is super convenient.Finally, switch your receiver’s input to the correct one that corresponds to the RCA input you used. On my Yamaha, that was Audio 1 or AV3, but it may vary depending on your model.After setting it up this way, the adapter works flawlessly! I’m using it in a spare room with an older receiver, and now that setup feels completely modern—maybe even more up-to-date than some new receivers, thanks to Bluetooth 6.0 support. Streaming Apple Music sounds crisp and clean, with no dropouts or lag.Final thoughts:If you’ve got an older receiver without built-in Bluetooth, this is an absolute must-buy. Don’t return it just because it doesn’t connect right away—chances are, you just need the right cables and input settings.Pro Tip: If you’re unsure about your setup, just ask ChatGPT how to connect your specific receiver and this adapter—it saved me a lot of frustration.5 stars. Highly recommended!

Wowww… Great small Bluetooth receiver
If you’re looking for an inexpensive LDAC Bluetooth transmitter, you have to try this one. Ugreen has a good reputation on their products, and this one is not an exception. Excellent value for the money.

This is a fantastic little device. My home stereo system is non-Bluetooth and just set up for playing my vinyl. This device allows me to play music from my phone. I’m still an album guy and my music is either copied from cds or purchased from Apple, etc. The sound is remarkably good. Easy set up and completely recommended!

Works as expected, small so easy to hide on the sideboard. Good Bluetooth range.

Works exactly as it should.My computer speakers have two sets of inputs, with one serving my main desktop.I wanted to have a way to also connect my laptop without the need to constantly having to plug and unplug cables.So I thought, why not give Bluetooth a try?Since my speakers do not have integrated Bluetooth, I needed an adapter.After some research, I landed on this UGREEN Bluetooth Audio Adapter.I’ve been a huge fan of UGREEN products for a long time, namely with their cables, adapters, and USB hubs, so I decided to give this a try and see how it goes.And goes it did.Setup was super simple: RCA to 3.5 mm to the second input of my computer speakers, and USB C to USB A to a multi-port USB charger.Upon first power up, the adapter automatically goes into pairing mode; my laptop paired with it right away without any issues.The sound quality is very good, with no noticeable drops.Though the fidelity cannot compare to a wired connection to the audio source, in my opinion, it is good enough for the average listener, but if you are a HiFi audiophile, you may want to look elsewhere.In terms of audio sync. or lag when it comes to watching videos or movies, I did notice the slightest bit, but within the realms of milliseconds – you have to look really closely and pay attention to notice. In my opinion, the average viewer will not notice.Where you do notice audio sync. or lag is when some gaming is taking place – based on my observations, I noticed a full second, not that bad where it becomes infuriating, but enough to be noticed.Overall, if you’re looking for a simple way to stream Bluetooth audio to speakers with no Bluetooth capability, look no further, this will get the job done!
