Yes, we put the volume on our Siemens Gigaset handsets on a maximum - but then it's fine. So reserve is no longer, therefore one star less. Otherwise, we call almost exclusively with the headset and the handset on the table or in your pocket. The free hands a reward for the unfortunately somewhat thin acting cable which then herumschlappert one.
The intelligibility on the opposite side must be excellent. My mother complained the last time, hard to understand me when I phoned without Headset ...
