The Jabra Bluetooth Headset Classic is a good device that is used for everyday use of. It has good portability. Both wearing with or without underwire goes smoothly! Both versions keep very well in the ear. The sound of the unit is very good. I just had to first get used to it that I can not hear anything with the other ear. Previously, I have indeed used headphones. In addition, the device connects easily with your mobile phone. This works even if the caller is already on the phone. The first connecting to a mobile phone was very easy. The battery life has been very convincing. I have the device now one week into use and it does not have any signs that I have to load it. I have used it from the 7 days 5 days and on the day of about 1.5-2 hours in use. So a very good device that I highly recommend.
