Model ST150 is a sophisticated amplified business telephone that can digitally adjust frequency-specific volume levels so that any user, especially those exposed to harsh noisy environments, can comfortably and clearly hear a caller’s voice. It boasts highly flexible sound settings: incoming voices may be amplified by up to 50dB with extra amplification for high frequencies. The internal acoustic chamber also restores low-frequency components in the incoming voice signal, allowing the speakerphone to deliver a crisp acoustic experience one would have only expected from a high-end conference speakerphone. The huge 7.4 square inch display allows a user to read the screen comfortably even from a distance. This phone also features a quick and easy way for a busy user to stay in touch - even out of the office. With a touch of a button, incoming calls can be set to be forwarded to a mobile phone.
