I bought this for a 2000 mile road trip, and chose this model because of the large capacity. We have ordered these pjs many times. The bass was very present and while the highs were slightly less crispy than the Razer set, the difference was negligible especially considering all the other benefits these headphones had. It was so frustrating which typically meant I’d give up and rarely wear the shoes I could never get to or see. They are light and easy to walk in. Hooks work great. Washed them and air dried them and smell went away. You buy data from App and its available for use immediately. A couple of years ago they changed the formula and it was no good. This printer is pretty good.
