Well, I have to say I just bought my first pair of these things for temporary use while the real stereo is boxed up. I've had them about a week, and so far I'm finding them completely unusable and absolutely obnoxious to have stuffed into my ears. I anticipate returning them to Amazon shortly.
On top of that, I don't understand what all the fuss is about re: the sound. They don't sound all that great to me, but perhaps I'm spoiled. This is no better at all than my full-size speakers with regard to detail, and the lack of a soundstage is just vexing. I cannot for the life of me understand why anyone would want to listen to headphones unless forced to, particularly these rotten things.
Any good tips out there how I might make these things fit/feel better? Basically, it feels like I have 4 huge cotton balls stuffed into one ear, and two in the other. The perceived difference is so aggravating I'mm going nuts.
