Creative Technology recently announced the Sound Blaster MP3+ and Sound Blaster Go! portable USB Sound Blaster sound systems. The two systems are lightweight — smaller than a typical PDA — and offer numerous connectivity options, including optical digital input and output plus analog inputs and outputs that include Line-In, Line-Out, microphone input and a headphone jack with volume control. A removable clip is also included, which enables convenient attachment to a back of a notebook display. In addition, the Sound Blaster Go! includes noise cancellation headphones that enable optimal music enjoyment in noisy surroundings. The Sound Blaster MP3+ is priced at US$59.99 and is slated for availability this month, while the Sound Blaster Go! is priced at $79.99 and should be available in July.
