Purchased new as a spare from Soundhouse on 2024/09/30. It has been opened but is unused. All accessories are included as shown in the photos, except for the instruction manual. The transmitter (microphone) has both XLR and 3.5mm connectors, allowing you to switch between them. This means it can also be used as a replacement if the XLR on your transmitter breaks. This listing includes a total of three transmitters and receivers. It was put in a separate, commercially available case immediately after opening and has not been used. Just to be sure, I tested charging it on December 20, 2025, and it charged fully without any problems, so I don't think there's been any deterioration over time. *The case is for another identical product, so it is not included.* It is still under warranty, so I will accept returns for any defects upon arrival. However, please be aware that I will keep a record of the serial number.
