Good headphones. Works great even with an iPhone. Clear that you not use headphones from Bose get at this price, but it is enough to fully audiobook listening to what I'm doing most. Even the speakerphone works well. It has also yet no one complains that the connection quality is bad. The battery running time. Some days you can use it. Only the USB connector is Mini USB, not charged with a battery charger for an Android phone. Too bad, but not bad.
