I liked the detailed provided instructions on this package. Very comfortable, but will have to apply vaseline or slick hair shine serum between the top crisscross pieces, & on each side of the inside of the shoe where the straps are connected to each side of the shoe. This was purchased to install into a golf cart so that we could play music while driving around. I?ve owned Nike pro combat under armour in the past but I have certainly found a new go to here. It is a great idea but because it breaks so easily it is not worth the price. ???????? You can still hear everything around you but not loudly so its just right. Ive walked around and the earphones stayed in place. Prefered a wired headset to another wireless set up or a mic stand Haven?t used extensively yet but so far it seems comfortable and works well. When the earbuds are in water they interact with the touch sensitivity and turn up the volume turn down the volume stop this song and turn off and on.
