I have to buy a pair of these every year because I wear them so much! I go through earphones like crazy ,these were durable , sound was good lasted longer than any other one ive had and they are so cute i can match them to my gym outfit or phine case Overall very satisfied with this trainer. It comes with only a few simple pieces, that are easy to set up. This is just the addition I needed to make the most of this space and I love the industrial look. Im done with overpriced hardware as the competition for excellence and good quality is so high these days. I havent checked but I believe I received every one as pictured and that made me happy! The included manual lists all of the controls and tap sequences which are fairly intuitive. I guess it’s been a part of my motivation as well knowing that I’m going to sweat lol meaning loss of water weight or whatever ever weight that drops off of me because of this beautiful invention. This was an easy read which flowed well.
