The Bluetooth TTS Speakerphone is compatible with most Bluetooth mobile phones. The Text-To-Speech system announces instructions for the users in 5 different languages and also indicates the status of the Bluetooth device. It also announces the name of the incoming caller (or phone number if the contact is not loaded into the Speakerphones phonebook). Fully portable, it is an ideal wireless communication solution for in-car or office use within a maximum range of 10 meters. Built-in with Echo Cancellation and Noise Suppression, the Bluetooth Speakerphone provides you with impeccable sound quality in full duplex mode.
