The cushion is thicker and better shaped, which further improves sealing to the ear. Nice crisp switches. The last few I?ve been primarily wearing the Nike ?Free Runs?. This means you are listening to your audio without interference from the outside world. The lighting effects are nice. You can really feel that the material is more high-quality and it doesnt track as much dust as the other silicone cases on the market. Where the back of the sole comes up to hug your heel was jutting into my heel a bit and while not a big deal, it would likely be a big deal after wearing all day. The top is constantly coming off. Light flexible shoes/slippers comfortable for short walks. I?ve had to replace my UE Boom cord three times due to breakage or loss, and it drives me nuts that other cords with the same type of connection cannot charge the speaker.
