Voice quality is very good

I use the BH-121 only for telefonieren.Die voice quality is very good and the microphone obviously. It is a pleasure to call it. Calling a long day with 3 to 4 hours keeps by the BH-121. Since the last update of the battery level is displayed on my Lumia. The earphones fit well and wear comfortable even over longer periods. The clip is a weing weak and holds only to reasonable margins, however, the BH-121 is pretty easy. Operating the phone is simple and intuitive. The main key has a good tactile feedback.
