I received something completely different from what I purchased. Therefore, I don't know how to use it. I believe this is the correct name. The images show everything included. Please feel free to ask any questions in the comments. A case is also included, but I don't know if it's official. I couldn't find the same case online, but the box looks like it might be. No claims, no returns. Therefore, I want you to feel comfortable purchasing after asking any questions in the comments. Thank you. Sennheiser
