This new model has hard , cheap solid plastic outer sole with no cushioning. I just replaced these a few hours ago before writing this review. They were very easy to put on. Well, as other reviews have mentioned, either Rocket Dog has really gone down in quality, or this is a knock off. Otherwise, it is great for organization and it?s price. It does come with several sizes though, so this is a subjective problem (that is common with any earbud really). Im 52" 125 36-28-38 standard dress size 6 and the small fit a bit on the big side! The headset occasionally stops working then resets on its own. happy son! Twist from bottom but certainly not bendy as advertised
