The card can transmit audio to wireless speakers. Features that are usual to the X-Fi series, such as CMSS-3D and 24-bit Crystalizer aling with EAX Advanced HD positional audio. The package includes a pair of earphones with microphone attached.
Additionally, the card provides theater DSPs such as Dolby Digital and DTS Surround through PowerDVD. Would you want to use this on a gaming notebook as an audio enhancement? While the card does provide features such as CMSS-3D and EAX Advanced HD, the audio processing itself isn't native. The card doesn't feature the CA-20K series audio processor, so there isn't a performance enhancement on offer. The card is priced at US $90. More details are provided on theproduct page.
