La calidad de sonido de micrófono está brutal, el sonido de los audífonos muy bueno. Without a second thought, I bought the new one. update: headphones last over 15 hours on one charge Ive worn Tevas for years and these are as good as any with one exception the heel strap is none adjustable which is not a deal breaker as the fit is ok but would prefer to have the option. I wanted a second color of this as I wear my first one to work almost every day. Directions were clear, feels rather sturdy, very pleased! I am between a 7 and 8 with shoes in general. I brought these inside the package was opened wham she put on like walking on a cloud. I?m so glad I went with these four individual shelves for versatility. So these ear buds worked fairly well while they lasted.
