Despite the facts that there isn't much appropriate 3D content, and the viewing angles required for the 3D effect are limited (as was described in our Nintendo 3DS review) the list of glasses-free 3D gadgets increases. The HTC EVO 3D smartphone was the latest addition, but certainly won't be the last. Perhaps not many readers have heard of the Chinese manufacturer Gadmei, although there is at least one reason to become acquainted with it. The company has released its P83 portable media player (PMP), which is capable of displaying 3D videos and images that are viewable without glasses, and is certainly one of the most inexpensive devices of its kind offered so far.

Of course, the user must be able to get the 3D content, upload it to the device and "add the file name in front of [3D]" as the product page roughly explains. Apart from the 3D effect, the P83 is a rather ordinary PMP. It has an 8-inch 1280x768 (WXGA) screen, and comes with 4GB of built-in storage and a memory card slot (MMC, SD, SDHC) supporting up to 32GB capacity. The connection comes via USB, which also works in the host mode (it allows users to connect a pendrive directly to the device). Most popular audio, video (with subtitles) and graphic file formats are supported, and the device also works as an e-reader, as it supports a number of text files.

There's no word on what hardware or software is used. The product's dimensions are 220 x 138.5 x 17.8 mm (8.66 x 5.45 x 0.7 inches) and it weighs 516 g (1.16 lb). Gadmei P83 is sold online via Brando and is priced at US$179 plus US$3 shipping worldwide.
