Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.

Customers like the performance, ease of installation, bluetooth connectivity and value of the network interface controller adapter. For example, they mention it works well, the drivers install automatically and that it allows use of Bluetooth peripherals. That said, opinions are mixed on quality, connectivity, signal strength, and sound quality.

Customers are mixed about the connectivity of the network interface controller adapter. Some mention that there are no pairing issues, the connection is reliable, and it pairs easily enough.

Customers are mixed about the sound quality of the network interface controller adapter. Some mention that the sound is good, and they can hear me just fine, while others say that the audio is horrible, cuts out, and starts breaking up. The range is absurdly poor, and the adapter before the audio starts breaking down. Some customers also get some crackling noises.
"...and pair under both of the previous options, but I had a lot of problems with sound quality, particularly with white noise...." Read more
"...Voila! I now have Bluetooth speakers, and they sound great. The connection is reliable and stayed selected thru several reboots...." Read more

There was a problem filtering reviews right now. Please try again later.
For my setup, I have full tower pc behind a plasma tv and am mostly using this to pair with a really cheap wireless headset (for chatting while gaming). It is working perfectly with the Kinivo (great sound, great signal, relatively painless setup). Decently fast shipping. Can't think of any cons.
In case, you are trying to decide between other products; here is some more info for reference:
1. Note: I will be using the smile.amazon.com links (proceeds towards non-profits of your choice). If you don't want to do that, just replace them with www.amazon.com.
2. My (admittedly cheap) BT headset is an "eForCity® Silver Bluetooth Headset". Amazon page - eForCity® Silver Bluetooth Headset
3. The first BT dongle that I tried (unsuccessfully) and had problems with was a SANOXY USB. IIRC, this was just using the basic Windows bluetooth drivers. Maybe it would have worked fine with a higher end headset... but since I was able to connect headset-to-phone without any sound issues, I'm blaming the drivers on the dongle. Amazon page - SANOXY® USB Bluetooth Wireless Adapter for HP, Gateway, eMachine, Dell or ANY Laptop/PC Running Windows 98, 98SE, ME, 200, XP, Vista & WINDOWS 7
4. The second BT dongle I had tried was the SoundBot SB340. This one had some CSR brand drivers but I also had a lot of problems getting my generic device to work correctly / not have horribly sound quality. Amazon page - SoundBot® SB340 Bluetooth 4.0 USB Adapter Universal Plug and Play Dongle Class 2 Transmitter (Newest Bluetooth Version Available) Ready Adapter w/ 3Mbps Data Transfer Rate and 10 meters Range, Compatible w/ Windows WIN8 WIN7 Vista 2003 XP 2000 Me 32/64 ...
5. I think I could connect and pair under both of the previous options, but I had a lot of problems with sound quality, particularly with white noise. No such problems with the Kinivo (I've already used it on Steam voice chat and my brother reported that I was coming in loud and clear). For the first 2 dongles, I had originally tried from my USB3.0 port which I later discovered USB3.0 can can interference problems with any wireless devices that use the 2.4GHz spectrum. I did try from my USB2.0 port as well, but no luck there either. The only major change since the first 2 is that I replaced my old 2', non-powered USB2 hub with a 6', powered USB2.0 so that it gets out from behind the TV better. This probably helps, but I believe my white noise problems on the other dongles were driver issues as I had also tested with the TV moved out of the way and clear LOS between the headset and the old dongles (and maybe 4-5' away) .
If it works this well for my el cheapo headset, I imagine that you would get even better results with higher end headsets.
disclaimer:
I am by no means an audiophile. I probably have a slight hearing problem (too much loud music lol). But I'm not deaf either and I am basing this not only off feedback via a recording app but also live chats with someone at the other end. Hope that helps!
