I used this a few times after purchasing it, but the noise canceling feature activated when I tried to record loud sounds, which prevented me from using it effectively. I was able to record normal voices without any issues, but it didn't suit my intended purpose, so I'm putting it up for sale. I accidentally bought two with different connectors, so I'm selling them as a set of two. One of them is not in a Japanese package. I plan to ship via Takkyubin Compact with simple packaging. Thank you for your consideration.
