The product should ship with 3 or 4 silicon caps. It comes with a variety of ear plug options. The rack is just poorly painted. Only thing I dislike? Its a standard size. I LIVE in my Orthaheel Tide flip flops and have for several years. SO great that the fact that they are wired doesnt matter! I will update this review if I find any issues going forward. Nice sturdy case, excellent quality I started recognizing some nice bass tones pulsating into my ears too. I thought that was £200 down the drain until I purchased these and they are great - I can now use my AirPods pros and run!
