So far, I must say that the Explorer 50 suggests quite well. Unfortunately, I can only play my first impression as I got it yesterday. Processing for the price is right, reach the connection is satisfactory. The fit is always relative to see because each has a different ear, but so far it fixes into place. A star I nevertheless draw from because the volume but although some reserve is sufficient upward would have been desirable. In addition, included was unfortunately only a very short USB cable and not even a power plug. Thus, I think that the 4 stars are justified. All in all, no Very good, but only a well.
If the long-term test something unexpected occurrence I will complement the recession yet.
Addendum .... After wearing long it expresses already clearly. And you have even an hour after the store feel to have the part still on the ear. Of course, this need not be the case for everyone, as I said each ear is just anders.Werde keep it uncomfortable. Nevertheless, I'll stay with the 4 stars because of my ear, the headset nothing lol ...
