The new animal prints are stylish and fun! I just didnt use them. sensor has a really nice low lod with 0 tracking issues. Thats why it has good noise cancellation. Secondly, the Bluetooth disconnects completely when they charge. The Sennheiser HD 650 headphones are open dynamic, well designed, well made with high quality materials and comfortable to wear. I thought maybe I had made a mistake, then as it kept happening and the audio started working only intermittently I thought I would try new cords and see if that was the issue. El sonido tiene mucho predominio de bajos, pero no enturbia el resto de frecuencias, medios calidos y agudos definidos pero menos resueltos con respecto a las demas frecuencias, la app agrega poco valor puesto que no ofrece demasiadas opciones de control y tiene muchos bugs, no permite actualizar via OTA, para actualizar deberas bajar la app en la pc y conectarlos vía USB. If youre buying this I would suggest reading something of any of the three characters so you have a grasp on who they are. It does cushion your heels from from walking on hardwood surfaces but if you suffer from any foot or back injuries these are not great for the long term.
