I recorded tests 2-3 times, but I hardly used it. Operation has been confirmed. It looks clean with no signs of use, but it has been stored at home for several years, so please purchase only if you understand this. * Since it will be shipped from Okinawa Prefecture, it may take longer than usual for delivery. Please purchase with plenty of time. * The sponge that covers the microphone may be slightly crushed for packaging size reasons. It should return to its original shape immediately after opening, but please purchase only if you understand this.
