So I got an Aeon 2 Noire at canjam a couple months back, and recently, I've been noticing some channel imbalance with the right cup, where it'd be about 4, 5 decibels softer than the right. But I decided against going with an RMA immediately since I'd already RMA'd the original unit for mechanical issues. Interesting thing is, is that the channel imbalance comes and goes, after running some tests, I've discovered the following. Going to a loud volume, around 10db over what is considered a relatively loud listening volume, will result in a slight crackle in the right channel, and then going back down to a normal volume would fix the imbalance for some time. Also, when it has the channel imbalance, playing at the bass hump frequencies, 100-150Hz will result in buzzing in the right channel. I'm guessing this all but confirms that they are using passive electronics to achieve the bump in the lower? midbass. Have you guys found anything similar?
