Incredible battery life, in my case lasted more than 5 hours. Pero en realidad los compré para usarlos en llamadas y conferencias en linea , lo cual no me funcionaron muy bien no me escuchaban o se escuchaban muy bajito lo cual mejor opte por usar auriculares de cable y con micrófono. And the colors - orange here - look amazing! 5, but they don’t do half sizes and their size 9 fits me perfectly. With this new set of headphones, the cable is about twice the length and comfortably fits behind the neck. Ive contacted the manufacturer, and am not pleased with their service. Only thing, we have two cats and a blonde dog who sheds. crap. This is sooo beyond perfect I would give it 10 stars! That would make this a better product, and more of a permanent solution.
