EDINBURGH, Scotland--March 26, 2001--Wolfson Microelectronics Ltd. today announced its audio codec products have been selected by VXI Corporation to supply the audio subsystem used in the firm's new fully functional Universal Serial Bus (USB) Digital headset systems; the monaural Parrott Aruba and the binaural Parrott Caribbean. The two new headsets, based on the successful WM9707, support full two-way digital audio USB operation and employ the same cutting edge technology as that of the highly successful VXI Parrott line of speech recognition headsets, thus bringing a greater level of voice clarity to the USB port.

Applications for the new Aruba and Caribbean include Internet telephony (VoIP) PC to PC and PC to telephone, speech recognition, digital voice recording, voice chat, voice recording and on-line games as well as listening to music and MP3 music.

``Our customers are very discerning,'' said Costas Papadopoulos, vice president of Research and Development of VXI Corporation. ``That means they expect the highest voice fidelity and more features including stereo listening, microphone mute and longer battery life with notebook computers. Traditionally, these have been mutually exclusive, but the WM9707 enables our engineers to meet or even exceed those demands with the new Aruba and Caribbean digital headsets.''

``The expanding use of the Internet for real time communication is what makes this an important design win for Wolfson'', according to Julian Hayes, Wolfson's vice president of marketing. ``It is critical that we use our technical advantages to enable new markets''.
