Business bluetooth 4.2 is the same as in the photos. I fell!!. Way to go. It lasts 1 week on the battery, using it all day. Speaks in English (Solo). Two devices are discussed very well for people who have to work with two mobile devices. Very glad the truth.

It weighs a little more than another I had and it's also thicker, but I imagine it's all getting used to. The sound is not bad. I have to prove it more time to give my own opinion
