The CELPIP exam will not allow you to use your own headphones or microphone. For the speaking section of the exam, the testing facility will supply you with a headset and microphone.
All of this gear is hand-picked and rigorously checked to make sure it can pass the test. It is strongly forbidden to bring your own equipment, as doing so could lead to technical difficulties or give you an unfair edge.
Thus, it is crucial to rely on the test centre’s offered equipment to guarantee a consistent and fair testing environment for all students.
