Pourquoi ? I wasn?t expecting them to even be there or functional, if not from the physical damage then from the water. Can?t even make it to work and back without the battery dying. Installing couldn?t be easier. ????I was especially surprised with the clarity of phone calls on both ends; it suffers a little bit in noisy environments, but still able to hear clearly with no issues. The build quality is A+ and the Sound is crystal clear. Easy to wash! I always tie my tube up to my cooler tube with just regular white rope. I bought an Apple iPhone 11 Pro and didn?t realize the charger wouldn?t work in my car. I have been using this for several months and I just dont like it.
