El envío muy rápido y llego en perfectas condiciones. I did not like that these did not come in a box with tags or anything. Music reproduction is very good but I have to select the album or playlist on the phone before setting off. Not sure what size chart they used when manufacturing these, but it surely isnt the same chart for fitting the NB 990 series. I just got this M90, it?s smaller, ( see photo)than but the sound is HUGE ! >This shoes is perfect during summer/fall. Even the resort workers were complimenting the sound over their own sound system. However, if you need an additional one for this wireless charger, make sure you look at the specs if whatever you buy (or use) to maximize charging speed. Delivered within time stated and came as described. It is the "cats meow".
