Thank you for viewing. This is a set of a wireless headset and a lavalier microphone, perfect for presentations and events. I purchased this item about a year ago on Amazon for around 10,000 yen and used it at events 5-6 times. Since I no longer have events, I've decided to sell it. It still works without any problems, but please be sure to charge both the transmitter and receiver before use. *The images from the third image onwards are taken from the product description on the internet. *I have another set of the same product (purchased at the same time). If you want two sets, please comment before purchasing. I will offer a small discount. 〈Product Specifications〉 - Brand: Alvoxcon - Model: Wireless Headset/Lavalier Microphone - Accessories: USB charging cable, microphone, receiver, transmitter, clip, headset - Uses: Live events, presentations, school events, weddings, training, church services
