A:AnswerI usually connect to usb on my work computer for about an hr and when I connect to my cell phone, the icon will show the battery at fully charged.
The charge will last me about 2-3 days depending how long during day I use them.
A:AnswerThese are definitely iPhone 7/7plus compatible. I have a 7plus that I used these with. You pair them like any other bluetooth device and they are also capable of using to make outgoing and answer incoming calls.
A:AnswerThe short answer is no
When your controller is connected via Bluetooth, audio devices are not supported. To use a headset, connect your controller directly to your PC by using a USB cable or the Xbox Wireless Adapter for Windows or connect your audio device directly to your PC.
if your controller has a 3.5 jack you can connect a wired headset, but if I understand your question correctly and my assumption is that you have a wireless controller that is Bluetooth, then any attachments, such as headsets, are not supported.
Hope this helps
