Recently, to prepare for a long plane flight I bought a pair of Sony MDR-1000X Bluetooth noise canceling headphones. While I won't get into the specifics of these headphones other than that I have been really satisfied with them, when I returned from my trip I wanted to start using them at the office.
Seemingly that would be easy, as these headphones feature a 3.5mm input, but I am frequently walking around the office and I wanted to fully utilize the wireless features. While I could have just used any Bluetooth adapter compatible with Windows, I wanted to test out one of the features of these headphones — AptX technology.
AptX is an alternate Bluetooth audio codec from Qualcomm which aims to feature higher audio quality. Sebastian took a look at a pair of AptX-enabled headphones earlier this year, and I have wanted to check out the technology ever since.
After receiving the USB adapter, I first installed the CSR Harmony software from the Azio website. This is a piece of software that sits on top of the Windows Bluetooth Stack and enabled advanced Bluetooth features, including AptX, on certain Bluetooth chipsets.
Once the software was installed, I plugged in the device and found a new Bluetooth icon sitting in my Windows tray.
From here, you can simply right click the icon and search for a new Bluetooth device.
Once I put the headphones into pairing mode I was able to pair to them successfully.
And, that's it! Once you are successfully paired to an AptX device, you should see this popup from the Windows tray confirming that AptX is working. From here, you can use the headphones just like you would with any Windows audio playback device.
This certainly isn't a review of AptX audio quality, I will defer to Sebastian's analysis for that in which he calls the headphones he tested "audiophile-approved Bluetooth."
For a $12 investment, it seems like a no-brainer for users who already have an AptX-enabled device that they use on their smartphone.
