Holy cow is this slipper wide did not expect it to be as wide as it is. Perfect fit and look fantastic. Mic:The mic quality sounds good, just dont have the mic too close to your mouth because breathing into this mic is loud. Make sure your roof rack has a front and rear bar or you will not be able to use this. Overall I?m happy with it will see how long it would last. Stylish good looking without the highly coloured eccessively large suspension in the sole. ?? Battery life could be a little longer but its ok. I feel bad for not yet being able to send back the product for them to figure out how to fix it. The instructions are clear, and honestly all you really have to do is plug parts together, no Allen key or screw drivers necessary. amazing !
