Pioneer announced the S-MM251 USB-powered computer speakers, offering a built-in audio DAC and a cool bass-reflex enclosure designed to enhance lower bass frequencies. The S-MM251 is designed to connect quickly to virtually any laptop computer, delivering significantly increased audio output and better sound quality.
The S-MM251 has a modern form factor that resembles small domes, and features 1.75-inch metal drivers and control buttons for volume up, volume down and mute. For increased low frequency response, the speakers use bass-reflex enclosures. The speakers are connected and powered using an included USB cable, and the integrated blue LED in front of each speaker indicates a proper connection. Its built-in audio digital-to-analog-converter (DAC) ensures high quality sound with plenty of power.
Not much larger than a coffee cup, the S-MM251 is extremely compact and easy to transport, making it ideal for travel. The S-MM251 is available in black as well as a silver version designed to complement the color of Apple's highly popular MacBook Pro and MacBook Air computers.
