Review on Enhanced Plantronics S10 Convertible Headset with Amplifier (Discontinued by Manufacturer) by Fernanda Brown

This versatile speakerphone. It has many settings that can be adjusted for sound quality, including a selector switch to match the phone's impedance. What you can't see in the picture is a small wire hook that you can use to hang the headset over your desk when not in use. You have the option of using a headband or an ear clip. The problem with the headphone clip is that you have to remove the headphone pad to attach it. I chose a headband as it is more comfortable.
