Sony is a habit of creating quality products, only Headset HBH-DS980 (released in 2006/2007 /) could flaunted the directory without having to take the phone out of the pocket, and it was good (that is why I take off a star). If the product is very good anyway audio quality with headphones is reasonable, and of course there are better (but for this price hard to find). The small applications are very useful, like making the phone ring only to find it does not work, as on my old MW-1 that functioned very well, reading the sms is great when driving a vehicle, but nothing innovative, it's been years that they do. It is true that the speaker sound during calls is not very strong, so we can not do listen to the conversation around her, but good for me is not so bad, since I use the atria . Design side it is beautiful, it is a continuation of the range Xperia Z, and ergonomic. At home it is coupled to a Xperia so I have not encountered any particular problems when installing applications.
