Sony NEX-5N External Mic "Rumble" test (without Ext mic)

[skbrothers]

thanks for the reply, but I'm not commenting on the clicking noise (which I am well aware of). This is one of three test videos illustrating a deep rumble that can be heard with the external mic. I shot it in a closed bathroom purposefully so as to eliminate any wind noise as a possible culprit. Check out my first video and if you have an external mic I'd love to hear if you have this same issue. Not sure I'm going to keep this mic, if this cannot be eliminated/reduced.
