I already had this article before but the tie clip broke ranks. This item is doing more, we have not been able to exchange it. So I ordered on Amazon. I use it with my Galaxy Note II 4G, and is compatible voice features, it displays the caller's number. At each change piece Mp3 displays the title for 3 seconds (I had never lived), it has a very good battery life, sound is very good but I use another headset (high end) that one that comes with (much less efficient) .the radio feature / rds has excellent sensitivity. Too bad because we still can not memorize radio stations and the kit does not indicate the hour. Pay attention to in clip, it can rupture if there is too brutal. The display of information in blue is the most beautiful effect. The control its touch is very convenient. Other commands (change of track, stop, etc ...) to avoid having to leave the smartphone. Finally, wonderful article but it is preferable to use another headset and also to have a good Mp3 software, like mine (power amp).
