So I could have saved a few bucks and bought an after market pair. This directly addressed the problem shes had with previous designs where that area regularly gets scuffed up; requiring regular cleaning and polishing. Addition of little “bumps” to hold the earcups in place is a nice touch. These are really cool headphones for a good price. I searched forever trying to find a basic set of earbuds that did not have the irritating microphone feature. También otro día me invitaron a patinar y aunque no son para eso, también me funcionaron bien. I need every color! 5 stars would have been given except that the keys were not provided in the packaging and the company said to return instead of sending me keys. This is a review on A) for the refurbished version bought here and B) the MegaBoom itselfRENEWED MEGABOOM REVIEW:I received a faulty Mega Boom, for the first 2 months I was using it once or twice a week and always keeping it charged and had no problems. With the drawstring slackened off, and my high instep, the elastic compression of the upper is sufficient for everyday walking.
