※ Please refrain from price negotiations for this item. SONY ECM-NW10 This is a stereo microphone for voice recording that can be plugged into a Walkman. It has been stored without actual use, so it is in very good condition. I tested it with a Sony Walkman before listing, and it works perfectly. ※ The shape of the plug-in terminal is the same as WMC-NW20MU. #yupakuwalkman ↑ I also have other audio-related items for sale, so please take a look if you'd like!
