I have a Logitech Wireless Gaming Headset G930 connected to my Macbook Air which loses the connection to the headset every 5-15 minutes.
The headset is now several months old and I haven't had any problems until a few weeks back. Around the same time I restored my computer with first installing Yosemite and then a week later installing the El Capitan public beta (currently on Public Beta 3, 15A243d).
When the headset loses its connection I can still see the headset in the OS X speaker selector, since the USB dongle is connected. I can then reconnect the headset by unplugging and plugging back in the USB dongle.
Could El Capitan be the problem or could I have missed installing some software after restoring my computer?

After updating to Public Beta 5 the connection have been significantly better, only disconnecting 1 or 2 times per day
