If, like me, you've spent significant time and precious funds seeking out decent earphones for your portable media player only to end up having to try again, digiZoid reckons that its Zo personal subwoofer could save you from further earache and disappointment. About the size of an iPod nano and weighing less than an ounce, the Zo is said to work by dynamically adjusting audio signal input to present the listener with clearer bass, crisp highs and smooth mids without having to increase overall player volume.
Rather than increasing throughput volume, the SmartVector sound contouring system of the 1.5 x 0.38 x 2.75 inch Zo offers 32 incremental bass intensity profiles. Scottsdale's digiZoid claims that such a system helps its electronic subwoofer fill the audio spectrum gaps that earphones are unable to adequately cope with, by both enhancing signal clarity and damping out digitally-induced artifacts that can cause distortion whilst at the same time adding subtle time delays to give the user a more natural listening experience.
The company's Paul Berg said : "This technology represents five years of extensive research, development and testing. The result is a tremendous breakthrough in high-quality sound for portable media at a perfect time considering the mass convergence of communication, audio and video entertainment into these devices."
For the specification-hungry, the U.S. designed and manufactured Zo benefits from a frequency response (20Hz - 20kHz) of plus or minus 0.25 dB, a noise level of -87.9 dB(A) and dynamic range of 87.6 dB(A). The intermodulation distortion at 10kHz is 0.015 per cent, total harmonic distortion is 0.003 per cent and stereo crosstalk is 89.4 dB(A).
All of the device's plug and play operation is controlled from one multi-function switch. The LED scale indicator to the front changes from green (lowest setting) to red (highest setting) for a quick visual subwoofer profile check. The Zo can be used with any audio device with a 3.5mm stereo jack including media players and smartphones, portable gaming devices and desktop or laptop computers and home stereo receivers or docking stations and car stereos.
Its lithium polymer battery should be good for up to 12 hours playback (depending on chosen subwoofer profile), full charge time takes two hours but there's a rapid charge option that will see the battery reach 80 percent capacity in an hour.
The chrome and black gloss Zo is available now for a special introductory price of US$99.
