The Desk Speaker Stand CSS-25 allows users to handle handsfree calls with excellent sound quality, either on loudspeaker or private. The CSS-25 has a built-in microphone/speaker so that the user can hear the caller loud and clear in the room, which makes it ideal for smaller phone meetings. For private conversations there are two plugs ¿ one for a Sony Ericsson Portable Handsfree, and one for a professional headset with a 2.5 mm connector.
