Onvian USB Bluetooth Adapter CSR 4.0 Dongle Receiver Transfer Wireless Adapter for PC Computer Laptop Supports Windows 10 8.1 8 7 Vista XP - Upgraded Version

I have tried using every driver available for this and it still didn't work. Shows a Bluetooth signal on some drivers but doesn't connect to a Bluetooth speaker or an Xbox controller. On the driver windows defaults to, it doesn't show up at all.

This helped me connect an old PC (Windows 10) without bluetooth to a wireless Apple keyboard and mouse (also older). It was cheap, delivered next day, and connected right away. It took a while to figure out how to enable all the features on the KB/Mouse but figured it out with the right drivers. It did create some wake issues but I'm pretty sure it's not related to the adapter itself.

I recently purchased the Onvian USB Bluetooth Adapter for my wife's laptop, and I'm happy to report that it works great! This small and inexpensive adapter allowed us to connect an old laptop to our Bluetooth speakers without any hassle.Before purchasing the adapter, the audio from my wife's laptop sounded terrible when she tried to play her exercise videos. But with this adapter, she can now connect her laptop to her nice Bluetooth speaker that she previously only used with her phone. The audio quality is now crystal clear, and she's able to enjoy her exercise videos without any issues.One of the best things about this adapter is that it's very easy to use. We didn't need to install any drivers on our Windows 10 laptop; simply plug the adapter into a USB port and it's ready to use.

I had tried other dongles that either had terrible sound OR were too picky about connecting........ the Onvian 4.0 installed immediately in my win 10 laptop and the sound through my external speaker box was xlnt even at over 15ft away.Very happy, will def buy another!

I was very surprised that Onvian was more than willing to help ans sent me a replacement in short order :) The quality is very good, sound and range are great as well. A great company to do business with, thanks Onvian! Onvian Bluetooth Adapter USB Dongle CSR 4.0 Receiver Transfer Wireless for Laptop PC Computer

This product arrived with a small CD from which the driver needs to be downloaded. This is a problem as my modern laptop does not have a CD player. No details provided about the source of a downloadable driver that is compatible with this device

I bought a refurbished HP business desktop PC running Windows 10. This computer is a high quality screamer that I am most happy with. However, it lacked on-board Bluetooth capability. I had used other 4.0 BT adapters on an older device, but I felt that I should go to the newer 5.0 BT technology for the improved performance that is claimed. I purchased an Eveo 5.0 adapter from Amazon, but the result has been most disappointing - difficulties with recognizing BT devices, pairing, and maintaining connection. Even when connected, I was experiencing poor sound quality and dropouts. A TP-Link adapter was also flaky. This Onvian adapter was being used without any problem on an older E-Machines PC that I was using in a different location. I decided to order another Onvian and try it on the HP. I did have some difficulty with the install, but I attribute that to not correctly removing all traces of the 5.0 adapter. Once I got over that, I got a good install and all my BT devices were found and quickly connected. Performance has been great and stable. I see no need for anything that 5.0 is alleged to provide over 4.0 - a stable, quality connection is most important - and this adapter gives me just that.
