This is a set of two audio-technica infrared wireless microphones and a charger. AT-CLM700T/A x 1 AT-CLM700T/B x 1 BC50 x 1 These were used at home until recently. Power and sound output have been confirmed. A separate microphone receiver (compatible with the 2MHz band) is required for use. The reason for the "as is" condition is that the charger adapter is prone to coming loose. I used tape to secure it when I was using it. Charging was not affected. I will also include the rechargeable batteries, but they are old, so how long they will last or how much they can be charged is unknown. Please understand that these are used items and are sold as-is, with no claims or returns. Thank you for looking.
