※ Please consider this item as junk. This is a wireless microphone system with a total of 8 channels: 4 band microphones and 4 pin microphones. On 3/12, I performed a basic check for this listing. One band microphone had a lot of noise. Also, one pin microphone had a faulty switch. The other 6 microphones, excluding these two, are usable. This item has been stored at home, and I cannot guarantee future operation. Please refrain from purchasing if you are looking for a perfect product. ※ Please note that this item may be removed without notice as it is also listed on other sites. Thank you for your understanding. I strive for prompt and courteous service. Thank you for your consideration.
