Overall, yes, and I am glad that I can finally have APTX Bluetooth 4.0, CD quality connection to my amplifier.
When playing video from my laptop, there is no real delay for the audio when the audio is going via bluetooth to my hifi. Very impressed.

I am using this dongle to go with my Avantree Bluetooth Plug Adaptor to play music into my Hi-fi.
Avantree Roxa: Bluetooth 4.0 home music Receiver adapter with aptX codec for high audio quality, support 2 devices, never need to charge - Avantree LIVE ONLINE SUPPORT

TBH it works but it took a bit of effort to get there, but that is not down to the item, just the way windows seem to function and having looked at a lot of Bluetooth devices online a lot say you have to do it this way. I've yet to find a programme/app that can do this simply...
Sadly the instructions that came with this dongle doesn't cover what I am about to explain below (which is why I can't give this a 5* review)

The product came with a mini DVD with the software on it, unfortunately my laptop can't take little disks, but contacting Avantree directly, they sent the file to me in no time.

Installation was simple, but Windows does not make it simple after that. As has been mentioned by a previous reviewer you have to disable/enable audio on your laptop, but how do you do that I hear you ask?

I'll try and talk you through it (but you may have to use a bit of your own common sense as I can't write up every single simple thing)

If am using Windows 7 and I had to do the following.

*Install the software properly as required.

I needed a good Bluetooth transmitter, mostly for streaming audio, to plug in to an aging but dependable Samsung netbook running XP.
There’s lots of choice out there but genuine V4.0 Class1 versions are still rare. I’ve got a couple of other Avantree devices which have been straight forward to install and reliable so I plumbed for this one.
Class1 devices should give you a range of up 50mtrs, I’m consistently getting about 35mtrs which is pretty good.

The installation and configuration all went well, CSR’s Harmony software seems to be well designed but if Windows XP can throw you a curved ball it will, so a little care needs to be taken: I installed the supplied mini disc / did a restart/then plugged in the dongle / had to wait a long time for windows to think about things and eventually offer up a Bluetooth icon on the taskbar / then right clicked on the icon to bring up the “Add Bluetooth devices” menu. Pairing of headphones and some Bluetooth speakers then went fine.

The most likely hitch will be control panel default settings which may need to be tweaked. Actually it is all in the supplied Installation guide but unfortunately the screenshots are still in Chinese and the text translations are at best diverting:

“Remove any previous Bluetooth software on your system, the removal procedure is as bellows:”

“For more doubts about Bluetooth dongle setting, please kindly click Bluetooth icon”

“Why my Bluetooth headset can not steam music after successful pair and connected?”

A good quality device with excellent software but the UK importers need to provide much better install & config instructions.

Works exactly as I hoped for. I wanted this product to stream my music from my laptop to my Hi-Fi system. I purchased a Philips Bluetooth adapter that connected to the Hi-Fi then bought this dongle to connect to the laptop and stream to the Philips.
Installation was quite easy although Windows don't make the process simple that's not the fault of this dongle though. I read through the comments and someone had posted how they had managed to connect for streaming music. I followed the same procedure and although my system showed very slightly different screens, a bit of common sense and I had it up and running within 10 mins.

I would highly recommend this product for streaming music. In fact I want to buy another one to keep as a spare but they are currently out of stock here and need to be shipped from the US. I'll wait to see if they become available again then purchase another.

Badly written documentation, support website that doesn't open unless you Google it first. Took a long time to figure out that it only connects to speakers if the inbuilt laptop speakers are disabled first and then the quality of audio was terrible even though it is a top quality blue tooth speaker that works perfectly with other devices and the laptop gives perfect sound through other speakers....

I'll get the reason for only four stars out of the way first. The review sample that I received came with instructions that were in English, but some of the illustrations employed Chinese characters. For experienced folks this is not a problem, but it could distress the novice.

My install in an old Thinkpad running Windows XP went perfectly. I did need the install disc to load drivers, so if you are going to install this on a device that is not equipped with a CD drive you will need to contact the Avantree for a download. At the time of this review the drivers are not included in the support section of their web site. I hope this gets rectified soon.

When testing the install I decided to ignore the instructions to remove any other bluetooth dongles and their associated drivers before proceeding. I left my Plugable USB Bluetooth 4.0 Low Energy Micro Adapter configured on my laptop and installed the Avantree model without any problems. Where this one differs from the Plugable brand dongle is that one was very slow to find and connect to bluetooth devices, whereas this one performed almost instantaneously. More importantly, once paired and connected to a bluetooth speaker that I use this maintains that connection. The dongle that this replaced would frequently drop its connection.

Another wonderful feature is this is claimed to work at 50 meters. I actually tested it by walking my speaker into my backyard and music continued to stream to it at very high fidelity past the 40 meter mark (I could go no further without trespassing onto neighboring property. Bottom line is this outperforms every bluetooth receiver or transmitter that I have tested or used.

Needless to say, I am very pleased with this dongle and this is the one I personally recommend to friends. That is the highest recommendation I can bestow.
