A:AnswerYes, you may use a standard 3.5mm audio cable and connect it to the PS4 and the EVEREST 700. Although you may have to adjust the audio settings on your PS4.
A:AnswerThe 700s are "around ear" while the 300s are "on ear"
Basically, the 700s sit on your head around your ears. The 300s sit directly on your ears. Otherwise, there's not much of a difference aside from the size.
