Cheating tool, Sennheiser MX W1 wireless headphones - X2 Creative @ Space

The exam is a headache for every student, fortunately I have graduated, but I just experienced an exam, the civil service exam. It's hard to write essays, I can hardly write a few words in half a day, and in the end, I didn't even reach the required number of words. I guess I don't have a chance. This small wireless headset uses Kleer technology, and through a transmitter the size of a match, it can achieve wireless connectivity with any multimedia device, and it can also charge mobile phones etc. If your hair is a little longer and covers your ears, the examiner should not find you are wearing this while taking an exam.
