I can keep everything together and not have to worry about losing the detail brush, or any of the interchangeable heads. Throw these away. If you have been thinking about purchasing the Rachio, do yourself s favor and pull the trigger. Overall, I think they were a super value. 5 and still toes were scrunched. Now he wears these all the time. We use these at our company and I use them while I cut grass. Wait a minute! I wasn?t about to drop 150 - 200 on earphones for running. It looks like it was manufactured with the flaw allowed in the material.
