1 System inkl. Ive had four pairs of this same style and none have ever done that. I wanted to avoid anything overly bright that in my experience can lead to listener fatigue. Bassheads should consider the small lack of bass for some ears. Although I should have perhaps ordered a half size up. Longer than Id ever have them in for in one setting, anyways. Came in an nice the boce but only can hear out of the right ear. ;-P I am highly disappointed with the purchase and Im going to return it. Good for rain.
