- Hyper X Cloud 3 Wireless headset. All parts are present from the box, including the microphone, etc. Used for only one year so far, and the warranty is still valid for another year from Extra. - Invoice picture attached. Reason for selling: A study shows that headphones are harmful to our bodies. However, I inquired with the company itself, and they say all materials are natural and under strict protocols. So, whoever buys it, I advise them to change the earcups as a precaution.
