They're making continual improvements to the Bluetooth stack with each and every release now. Lastly, make sure you're using the latest build of Windows. If your speaker/headphones do not support aptX, it will use SBC, which sounds a bit worse - but most modern Bluetooth A2DP devices support higher bitrate SBC which sounds okay to my ears too.

You want Class 1 Bluetooth.Īlso the Microsoft stack supports aptX, so if you have a speaker/headphones with aptX support, the sound quality will be basically the same as a decently high-quality MP3 (about 192 to 256 Kbps MP3 in perceptual quality). Try to find one that advertises at least 66 feet range the old 33 feet range ones are Class 2 Bluetooth and will be much less reliable and more likely for the sound to cut out. There are hundreds of different brands putting their own plastic cap on this chip and selling it for $5 on Amazon. As a general rule you want Bluetooth 4.0/4.1/4.2.Īn example of a chip that works is the CSR8510 A10. Some chipsets are too old to work with the Microsoft stack. Then, if your Bluetooth adapter doesn't work, sell it or throw it away and buy a Bluetooth adapter that will work with the Microsoft stack. All other Bluetooth stacks on Windows 10 are junk.įirst, uninstall CSR Harmony completely. Your only source of Bluetooth drivers should be Windows Update, period. Use the Microsoft bluetooth stack that comes with Windows. Don't use CSR Harmony, Blue Soleil, Widcomm, or any other Bluetooth stack.
