Creative Xmod: This pocket-sized marvel sits between your playback device and your speakers or headphones. Its manufacturer, Creative, claims it can “intelligently restore the highs and lows for rich, crystal clear music.” Using a proprietary technology called the 24-bit crystallizer, it attempts to dynamically expand the compressed music, offers you a volume-gain control, and tries to fill in the missing jigsaw pieces in the soundscape. Creative has been criticized for claiming that the Xmod takes an MP3 beyond the quality of an audio CD, though there may be sound grounds for this. Since sound is based purely on perception, and each track may be different, results vary by track and by listener. Nevertheless, your MP3 music will overall sound much better and distinctly clearer than before. As the audio on broadcast TV and radio is highly compressed, the Xmod can enhance these, too. The device works out-of-the-box and requires no software drivers. It draws its power from the USB port of your Mac or Windows computer. Alas, this also makes it less portable, as it requires an optional power adapter to connect to your iPod, home stereo, radio or television. The second exciting feature in the Xmod is its ability to take two-channel stereo sound and reproduce it as surround sound, creating the illusion of extra speakers in the room for the listener. Compatible headphones can even recreate the illusion in your ears. The effect is doubtlessly thrilling. In India, the Xmod sells for an estimated street price of Rs7,999. Internationally, the price at various online shops ranges between $55 (Rs2,326) and $80.
