I bought the headset, because my phone is ringing general when I have the first 100 m in the car behind me. It was important to have a good reception, as well as a good voice quality and an adjustable volume. The good grip on the ear seemed assured by the earloop. As the particles came I of course immediately tested. The connection to my brand new cell phone was made without difficulty and quite fix. I also had no problems with the single button as opposed to one of my predecessors here. I could see the color change on the control knob well. However, I'm a girl and have the corresponding hands with the right fingers (S format). When I put my part on the ear, I was a little surprised. The earloop was perfect, but the in-ear speaker was about 1.5 cm below my ear canal. Unfortunately, the bar can not adapt. Therefore, and because the headset thanks to a USB connector not load on an ordinary wall outlet, I have deducted a star. The in-ear speaker holds but quite good in the ear. That the bracket is not sitting, falls in slightly longer hair on anyway and if not, that the headset from your ear slips then accesses but the bracket. The reception is great (as is the incoming voice quality with the interlocutor), easy to adjust the volume with a toggle switch, the standby time is good and the range of 10 m is sufficient, because you often anyway has the phone in your pocket or in the immediate vicinity , The answer by pressing the aforementioned button is as easy as hanging up. However, if you own the car has a lot of calls and has no voice control on the mobile phone, should consider another alternative. Can be made to the last dialed number by pressing the key that is only conscious the connection. If you want to call someone else, you should willy-nilly pause briefly until the new number is entered. By the way, I use the headset also in cooking, ironing and other household activities (prevents crooked, aching neck :-) - simply ideal for families Manager !!
