This product is NO good at all! En los cascos negros cuesta un poco más de ver. If anybody ask these are my new Yeezys! Overall, a good bang for your buck. Will not be going back to razer. I got this for a particular workout program that I started and use it for a lot of step ups and step overs, jump over the bench and some free weight lifting. They also dont stay in my ear as well, although that is more of an annoyance. (I used them about 10-12 hours a day. Slides are visually appealing, however, there?s no grip on the top or bottom so your feet are also ?sliding? inside of them. They really stand out.
