I use the speakerphone very often as a speakerphone for my S4. As are worlds between the speaker of the S4 in handsfree mode and the P710e. In the solution with the Logitech unit of Gesprächsparnter is really loud and clearly understood and all participants who are sitting around the speakers, transmitted acoustically well. Very quickly connected via Bluetooth to the S4. Very quickly connected via USB to the notebook and then used as a speakerphone for Skype. Again excellent speaker and micro-qualities. By the way (especially in connection with the smart phone) you do not need cables for power supply (as battery) and has very fast phone and speakerphone on the table and can get started with a free pitch session. Also helpful are the adjustment for mute and volume, Pickup or hang up directly on the device. May not be very cheap, but it is now finally time to use handsfree on mobile smart ....
