Aulker Bluetooth Headphones to my Plugable Bluetooth 4.0 USB Adapter

I cannot connect my aulker bluetooth headphones to my plugable bluetooth USB adapter, for my desktop computer.

Hi Mike,

Thank you for contacting us. I’m sorry to hear there have been difficulties with getting your headphones connected, and I would like to help.

To start, could you please tell me the model of your Aulker headphones, and the Windows version of the computer you connected the Bluetooth adapter to? I look forward to hearing back.

Thank you,
Plugable Support

Hello, I have the Aulker Q9 model, Bluetooth Headphones and I use Microsoft Windows 7 Professional.

Hi Mike,

Thank you for that information.

Please try the following step-by-step process, which should connect your headphones to your computer:

  1. Turn off Bluetooth on any devices in the area that you have previously connected the headphones to and “Unpair” or “Forget” the connection in each device’s Bluetooth settings. This is important to make sure it doesn’t automatically connect to one of them instead of to the computer.

  2. On the computer, click the Start button, then select Devices and Printers.

  3. In the Devices and Printers window, you may see an entry for your headphones. If you do, right-click it and select Remove Device, then select Yes in the next window.

  4. Press and hold the power button on your headphones until the LED flashes red and blue. Please ensure that there is a clear line-of-sight between your headphones and the Bluetooth adapter.

  5. In the Devices and Printers window, select Add a device.

  6. An icon for your headphones should show up in the Add a Device window. Click it, then select Next.

  7. The headphones should connect. Try playing music through them. If it doesn’t work, continue with step 8.

  8. Right click the speaker icon in the system tray at the lower right of your screen.

  9. Select Playback devices. The headphones should be on the list under Headphones/Speaker and possibly Headset. Select it under Headphones and click Set as Default device.

Please let me know how that goes. If this doesn’t work, please contact us at and reference ticket #179091, as I will need to take a more detailed look at how the Bluetooth adapter is installed on your system.


Thank you for the great help. I appreciate it. However, I was not successful. I followed steps 1-7 and tried to play music through my headphones. Nothing. So I tired steps 8 and 9. My headphones did not appear in the Playback section.

Something that I noticed. When I did step 5 and 6, it said that my device was successfully added, but then about 30 seconds later an icon at the bottom right of the screen appeared and read, "Device driver software was not successfully installed. See 2 screen shots attached.

If this even matters, on my home laptop, these exact Aulker Q9 model, Bluetooth Headphones connected with the Bluetooth in my laptop no problem.

But trying to connect to my desktop using this Plugable Bluetooth 4.0 USB Adapter is where I’m having issues connecting.

Thanks again in advance for the help. !](]( !](](


Hi Mike,

Thank you for trying that. It sounds like the drivers for the Bluetooth adapter experienced some sort of conflict while installing.

I would like to take a look at how your system is set up, which should help me identify what is causing the problem and how to solve it. We have a troubleshooting tool that gathers information and helps us find out what is going on in situations like this.

Please plug the device into your computer, then go to this page and follow the instructions there:

Please send the file as an attachment directly to, and put “Ticket 179091” in the subject line. The log files will include information about what is installed on your computer, so it wouldn’t be suitable to post it on a public page.

This issue was resolved by updating the drivers for the Bluetooth adapter to the latest version.

The current drivers for all Windows version can be downloaded on the following page of our website:…
