I then decided to buy this piece of kit, and it worked like a charm, and still does 3 months later. the pictures on the site do not do this shoe justice! It is currently the middle of a Midwestern summer, so I?ve only worn them indoors. The arm is easily adjusted. I only needed one but quickly found uses for the other ones. So convenient. I?d say you get what you pay for and noise cancellation is a must to me. The buttons are a little hard to get used to with skipping songs, and all the functions. ???????????????4?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????3???????????3????????????????????????SONY???????????????????????? When I lost my most recent pair, I bought these as a replacement.
