All seemed well initially. Windows 10 identified and installed a driver for the device, and in moments I had the familiar Bluetooth icon in my system tray. I was encouraged; this looked like it was going to be a textbook USB installation, a simple, trouble-free plug-and-play experience.
When I tried to pair my Bluetooth headphones, the Windows 10 Bluetooth dialog spun and spun and spun, for over a minute, before giving up. I tried this multiple times, putting the headphones in pair mode each time, only to have Windows fail to detect. Finally, I went to Plugable's website and downloaded the driver software for it. After installing and rebooting, Windows continued to spin, but this time it finally paired. Yea! Things should be okay now.
Not so fast. Sound on the headphones was of good quality, but it "hiccuped" frequently (skipped or dropped out). Worse, when I tried to play a video game, I discovered very quickly that there is a serious lag/delay in the sound over Bluetooth, as much as one second or more. Imagine playing a game where your sound is one second behind your visuals and you can imagine how crazy was my experience.
That's not all. After installing the Bluetooth driver software, my iTunes would no longer work. I restarted my computer and was able to start iTunes, but it would become unresponsive within 5-10 minutes and require killing with Task Manager.
I use my computer daily, and for the past month I had experienced no problems at all with it. It was when I installed this seemingly innocuous USB adapter that the problems began. I yanked it out, to confirm that it was the cause. It was. iTunes once again ran without issue, and I had no process hangs or any system stability issues, and certainly no delays over wired headphones.
Your mileage may vary with this, but it has been nothing but a headache for me, and I'll be return it and exchanging for a different brand, a brand with a proven track record of delivering reliable computer components.
"Here’s how to pair your controller wirelessly over Bluetooth, if you prefer: First, turn off the controller if it’s already on. If it’s on and paired with a PlayStation 4, hold down the “PlayStation” button and then select the “Log Out of PS4” or “Enter Rest Mode” option in the menu that appears on your TV. The controller will turn off.
Next, put the controller into pairing mode. Press the “PlayStation” button and the “Share” button on the controller at the same time, and hold them down. The light bar on the controller will start flashing. This indicates the controller is in Bluetooth pairing mode.
Finally, connect the controller to your computer like you’d pair any Bluetooth device. On Windows 10, you can open the Settings app from the Start menu, select “Devices,” and then select “Bluetooth.” The DualShock 4 will appear here as a “Wireless Controller” if it’s in pairing mode. You can then select it and click “Pair” to pair it with your computer.
On Windows 7, 8, and 10, you can open the Devices and Printers pane in the Control Panel. Click “Add a device” and the controller will appear as a nearby Bluetooth device. It will also appear in the list of connected devices here as a “Wireless Controller” once it’s connected."
Later when I tried to use it for audio with bluetooth heaphones and earbuds I ran into problems with connectivity, sound quality, etc. And after some experimentation and finding the issue persisted in both Win10 and Manjaro Linux with a few different sets of headphones and earbuds, concluded it was a flaw in the bluetooth adapter.
After posting my experience here I was promptly contacted by Plugable, who had obviously paid attention to the details of my write-up and pointed out that desktop components without integrated bluetooth don't often bother with shielding to prevent interference. They suggested moving the adapter away from other components, and quickly sent me a M-F USB cable to do so.
I previously had the adapter plugged directly into the rear ports of the motherboard, and sure enough, as soon as I plugged it into the USB cable and moved it a few feet away, my connectivity and sound quality problems disappeared. No more pops, clicks, poor quality, or troubles pairing or keeping devices connected.
I've tested it again in both Win10 and Manjaro Linux, and it works well in both and is fast to find and pair with my devices.
So, keep that in mind if you are using this adapter with a desktop system. If you're having some issues, it may be interference and just need some distance between the adapter and the motherboard.
