I think some people may get discouraged from buying this product because you have to purchase speakers separately, however you won?t find a good player with built in speakers. There is a slot thing designed to tighten them with a screwdriver but it doesnt work very well. One of my favourite crocs flat. The ones you put on, start your jam, your audiobook, etc. It makes it easy to see the items you may be hoarding. Going to order another pair *Their low profile is a plus. I just might wear these all my live long days. I am obsessed with these Nike?s! Toss em.
