Found the device name. and now for my big ones. Thats a great idea! Total 5 horas sin recargar. Other than that these are nice and for the price too. These are beautiful, comfortable sandals. After trying both I found that the sound quality of the HS60 to be far superior and the mic quality better. Seller responded to my messages all the time and was very understanding regarding my concerns. The sound is clear and also the most important thing is that the buds remain in your ears and they do not slip as all previous earphones I have used. Not a big deal.
