Pretty much good amount of background music and voice around her could be heard on my side. Will work. I bought her a pair so she can understand what it feels like to walk on a cloud! I am thrilled. I want to hear everything good and bad. The Wireless charging with the iPhone is great! Works well on my motorcycle and holds great. the right side doesn?t work Im actually using this as a shelf for my keyboard. )After two years of pretty regular seasonal use the mat is still as good as new and I have no scratches on my SUV roof from loading/unloading my kayak.
