For information concerning the Jabra Solemate there has 2 generations. The first generation exite in black and white only, but does not possess the nfc or Dolby Digital compatibility. The 2nd generation available in several colors (black, white, red, blue, yellow and gray). This one is NFC compatible Dolby Digital so you have to promote it during your purchase.
At first, when I will buy this place, I was not sure of the generation, but after calling Jabra, they informed me that the Solemate red, yellow, blue and gray were on 2nd generation. However, if you take it in black or white, it's double or quits.
For my part, the enclosure corresponds to my expectations. Its excellent (especially in dolby digital), very well finished, autonomy 10h, easily transportable, it has everything to be taken everywhere. I recommend this product
