have bought the headset, because with my old rubber earpiece gets lost and no replacement was to procure. Am pleasantly surprised by this unit. Plus points: -Einschalter On the side, no annoying fumbling behind his ear. -angenehmes wearing, at least I personally feel the unit little during wear. -When Turning the battery level is also always the same hip. - Solid earloop, because you have not the same fear that he abkracht. - Long standby time. Lasts a long time, I was now never to "low". Load enough every few days. Make calls sometimes even for 2 hours, then the battery is still "high" Conclusion: For the price, a top unit!
