Thank you for this information. The point is that this "ticking" is only present with the AAA battery on, both bypass and normal mode on. If I activate the noise reduction feature by turning on the headphone, the noise disappear (even if the Jack isn't plug), it doesn't change anything to plug it or not.

Hello Folks, I think I have a similar issue, when I have the AAA battery inserted into the right headphone, I can hear an annoying repetitive ticking in the right headphone, in both bypass and normal mode (for normal mode, if noise cancellation is turned on the noise disappear). If I use the bypass mode I need to take out the battery of the headphone and then the noise will stop. It's not a convenient solution for me since the battery can be easily lost and the battery door doesn't seems as solid as the rest of the headphone. Anyone with the same result, I don't think this issue is related to grounding issue like previously. Thank you in advance for your help.
