SONY Wireless Transmitter WRT Lavalier Microphone (Pin Microphone) I've used this for about two years, but since it's a used item, the previous owner's usage frequency is unknown. There are no particularly noticeable scratches or stains, and there is no tobacco smell. Sound input works without any problems. Included items: Main unit only [Notice] This product is used. I checked parts that would likely be used during normal use when listing the item, but I haven't checked every minute detail. Also, I cannot guarantee the condition upon arrival. Please consider this information as a reference. Please refrain from purchasing if you are looking for a perfect item. *The equipment used in the operational image is a reference example. Items shown other than those listed as included are not included. *As this is a used item, there may be scratches, stains, and dust. I have performed a simple cleaning, but please be aware of this beforehand.
