Hi, I've recently have picked up a pair of x10's from amazon.
I've been using them on my iPhone 4 first gen and there's no doubt about it they have great sound!
However, when I bring up the volume to max volume it seems the headphones are not able to handle to loudness. In short, when on the highest volume during some bass heavy rap songs there is bass crackling. I am currently using the R&B EQ built into the phone as bass booster just makes them crackle like crazy so I don't even go near that preset. Does anyone have the same issue as I am having? I've also read on another forum that I might have to burn them in. Is this true? I paid a decent amount of money for these and it would be a shame if these are only able to handle a certain volume limit.
