critical to consider!

Contrary to my many previous speakers I am not so completely thrilled by this headset ...
One thing first: It met quite reliable his service, with prolonged use, however, some things fall to negative, I want to list here times:

1. The headset reinforced unfortunately very strong high notes. Especially bad it is, for example, at the supermarket, where it actually requires only about 20 meters from the cash register to be away that the interlocutor gets earache. Even you can hear it but nothing that is probably the reason why this phenomenon elsewhere in the reviews scarcely figures ...
2. The build quality leaves quite a bit to be desired, after I (once about every two days) have the headset now about nine months normal use, already the cover of the USB connection no longer sitting and can not be closed, but stands out from the headset, which is inconvenient and easy even ugly. The windshield was sitting too loose from the very beginning and is then of course I eventually got lost, to cycling and phone calls is now not to think to some extent! Also "breaks" the headset and often very light in its two components, of course, always when mans do not need (for example, because it has only one hand free ..). But what do you expect from a well mixed plastic-rubber, which is also intended to be flexible?
Have 3. As others reviewers mentioned is the headset with two devices is not really clear, although it should be adapted.

On the other hand should be mentioned nonetheless that the headset is still good is serving and a really reasonable transmission and reception power has. The only question is whether such an unstable device are actually more than 60 justified ... I'll look around for alternatives!
