My Razer Nari headphones recently stopped accepting pairing from my computer.  I have had them about 2 years.  They utilize the USB Dongle for connection.  Windows is up to date, I have run the installation utility, all extraneous programs are turned off, but it just won’t stay Paired.  I can pull up the Sound Settings or Device Manager settings and will watch as Razer Chat and Razer Game both get added, then disappear, then get added, then disappear, and on and on for a minute or so, before they are just gone.  On a clean boot, both Chat and Game are both listed under Sound, but when the headphones are turned on, they both disappear once again.  Any ideas if it’s the Dongle?  The Headphones?  Drivers (I am told I have the latest one)?  Or is this just the end of the product’s life.  They still look really nice, be a shame to toss them over a pairing issue.
