Little hard to attach, but I was attaching it to the cover on my phone. I expect these will last him for a decade. I know how to put things together. I definitely recommend these! I was looking for another shoe after Asics changed their shoe. The battert life is long and it doesnt hurt my ears when wearing for a long period. A daft but very entertaining action film with a good cast. Ill admit, at first I had my doubts being the elitist that I am. The battery life is ridiculously long! and the shape of them is perfect- other ones pop out when I talk or che, or hurt after awhile.
