Cons - Does not always sit comfortable in your ears.
Really enjoyed these right out of the box. Sound does not change much through burn in period (fortunately). Wide soundstage. Not too bassy, just perfect.Good build quality. Appears to be a league above Meelec M9 when it comes to sound quality.
If you are able to get these for 40 dollars or less they're a best buy you should not let pass.
