Have for the first time want to try such a device to the phone (even if listening to music with Doro Seniorenhandy) to keep your hands free. From the results with this device I am pleasantly surprised. Gem. Description you get for something longer delivery time (coming from Hong Kong) a blister pack with earbuds and earloop, second Ohrhörknopf for wiring with the main receiver via mini-USB port, USB charging cable for the built-in Li-battery and a chin .- / English manual. In German this would be better, but I am also coped so. A few additional. Pictures would also possibly helpful. However, they are missing altogether. Operation and battery is signaled by blue / red LED. Loading, starting and mobile phone Bluetooth installation folded quickly. The external view shows the way the start button! The device needs some ear applying routine. The same is true for the operation of the Bluetooth phones. But works quite well. The sound with the main handset is quite useful. Who wants stereo, take the 2nd handset to. Then you but a cable has there again. Warning - volume limit! This thing can be quite loud. Who are not afraid of English. Demand -stationary guide has, I recommend these inexpensive mini headphones quite. I find the price / performance ratio is really good.
