WS-400S: Ready for Business The sleek WS-400S offers 1GB of internal flash memory to capture up to 272 hours of Windows Media Audio files on its built-in stereo microphone. It now features two new higher-quality recording modes, super standard play (SSP), and super high quality (SHQ) for better sound quality.
