A:AnswerThey're Bluetooth Im pretty positive they only pair with things that have Bluetooth and I don't think consoles like Xbox or PS4 have Bluetooth connection.
A:AnswerYes, this seems to be a problem with these. With us getting them at Best Buy though, all we can do per the employee at Best Buy is throw them away.
A:AnswerMake sure you keep the device towards your right side, as the right headphone is the one connected to Bluetooth.
It also could be frequency from other devices, which you can't really fix.
A:AnswerYes. Just use Bluetooth to connect them like you would do with any other bluetooth headphone/speaker. But pay attention you have to take both earbuds out, otherwise follow the instructions.
