content: This is a joke right?Edit: Incase its not, 2 sets of speakers and microphones are being placed together causing feedback. Noise cancelling headphones work by picking up external sounds in a mic mounted close to the speakers and reemitting the sound 180 degrees out of phase through the headphones. Because you are placing both the left and right channels so close together, you end up with lots of feedback, even cancelling some of the already cancelled waves, and just completely overwhelming the noise cancelling circuitry. When the headphones are on your head the sounds emitting by the speakers isn't getting picked back up by the mic in the other side of the headphones.

content: Just curious - have you tried putting them on your head? If so, do they feed back then, too? THAT would be a design fail. Carefully pointing the open headphone cups at one another so that they acoustically couple and as a result go into a feedback loop is not. Something behaving in an unexpected fashion when it's not being used as intended is not a design fail.-Pat

Alkalines will actually be cheaper in the long term, and rechargeable batteries such as Eneloops even more so.

content: Come on guys, the OP is only a kid!It's one thing explaining what feedback is, helping him to understand, but it's another calling him an idiot and annoying!Bit of a shitty thing to do, no matter what you think, or how ever many years of experience you have under your belt, you should be helping him to understand why his thoughts are wrong, not belittling him!
