Have gotten no satisfaction from them ALL THEY DO IS STALL. Really loved this case at first. It was try these out or buy a new pair of Bose since the o briginal pads in mine were shot. My wifes entire office uses this model as their standard. On my end, I heard the caller clearly. Después de desempacar la bocina y realizar algunas pruebas con diferentes tipo de melodías estos son mis comentarios:Calidad de sonido: Bastante aceptable, la reproducción de medios y altos es buena, brindándole cuerpo y brillantez a las voz y a los instrumentos. Have several pairs of Crocs. My only complaint is that in party mode, my new phone pairs with both speakers simultaneously, when it supposed to be hooked up to one "master" speaker, while the "slave speaker" is only connected to the master via blutooth. I have used less fluid, less smooth machines in gyms though, so if the weight limit isn?t gonna screw you up, it?s a pretty decent choice. Whether its a light drizzle, a torrential downpour, or its hot, clear, and sunny, these shoes are very comfortable.
