The Jabra Wave - Corded Headset is a very light headset, but the design is not for very sensitive ears. By means of the enclosed gel pads of the "Ultimate Eargel" it fits perfectly in the ear or ear canal. Annoying noise are kept by and you can move freely, without anything slip. To avoid wind noise is the micro a removable windscreen included, besides there are two cable adapter at: 3.5 -> 3.5 mm for iPhone, HTC, Blackberry, LG or Motorola; 2.5 -> 3.5 mm for Nokia, Sony and Samsung. The packaging is a reference sheet with a Limited Warranty (1 year). Is the warranty on defects in Germany 2 years, therefore I find this "guarantee" sinnfrei (but does not lead to the devaluation).
The device at the Fritz! Fon MT-F is easy, it only needs in the "Settings" in the "Audio" the point "Set up Headset" are chosen, a few seconds later you can acquit. The acceptance button can not be used at present, maybe that is taken into account in a later update of AVM.
The sound quality is excellent on both sides. Confirm my interlocutors that they understand me better now than before.
The negative reviews I can not confirm, perhaps here the Bluetooth device is actually evaluated. In the good price-performance ratio (currently 15 to 20 euros) a super addition to the Fritz! Fon MT-F.
