KNOWN ISSUE: Received these with Rode Go II kit years ago. They both developed inconsistent but minorly noticeable issue. Sometimes if the cord is bend the wrong way a very low hum is created. It's minor and not loud. If dialogue is being recorded at normal talking levels the hum can potentially be removed in post. It was an issue enough for me to move on to another set of mics. Includes: - two mics - two Bubblebee Industries Lav Concealers - two windscreens - two mic clips
