Finally, the new Echo is also expected to feature
improved microphone technology, but the source wasn't able to provide any specifics on that front.
In comparison to the PSP - 2000, the PSP - 3000 (marketed in PAL areas as «PSP Slim & Lite (with enhanced screen + built in
microphone)» and still marketed as PSP in North America and Japan) has an
improved LCD screen with an increased color range, five times the contrast ratio, half the pixel response time to reduce ghosting and blurring effects, a new sub-pixel structure, a
microphone, a new disc tray design, new button designs and logos, and anti-reflective
technology to
improve outdoor playability.
