The Jabra Speak 410 has brought a 100% improvement. Now the voice quality on both ends is as good as we would all be in one room.
Even if more than one person on the JABRA are fed off this is no problem.
I do not want to miss the JABRA spaek for my project status meetings and Stand Ups. Great price - performance ratio even if it seems a bit pricey at first glance, the part is worth every euro.
I welcome also, that it is to fit in a laptop bag / purse pleasantly small, it even comes with a nice cover that can be opened chute closed with zipper. Works flawlessly without any installation effort. Have it on both Windows and Linux in use!
