Mounting hardware design USES 2 PCS, equipped with EVA sticker in order to protect your car bar, will not scratch you. Material opinion: As described - ehite leather - Good feel. Plus it comes with a 2 year manufacturers warranty anyways. The charging box is super easy to use. It was easy to "fire up", and attach S-Voice to it. But these fall off of my feet as I try to walk in them because they are too big. That?s like a great dessert in a high end restaurant. on low gain i still had to keep the volume knob at about 9 oclock. So convenient to have it fold up on wall and unfold for use without having to open up a floor based structure. I wore them for the first time and the faux fur dye rubbed onto my feet.
