Aluminium finds use in newly launched gadgets for personal use

Onkyo Corporation, the leading Japanese consumer electronics manufacturer, specializing in premium equipment, has launched wireless headphones with aluminium housings. Onkyo has taken the wraps off a whole host of new headphones, including premium on, over and in-ear designs.

Onkyo's H900Ms are a closed pair of over-ear cans and cost £230. Like the brand's earlier bestseller A800s, H900Ms also use 50mm drivers with aluminium housings.

Aimed at the portable market, there's an extra-wide headband for added comfort. They're finished in black and gold, a colour scheme that features across the entire new range. The H500M (£130) on-ears feature 40mm drivers in a rigid aluminium housing and a claimed frequecy range of 7Hz to 40kHz. The gadget also packs in an in-line mic and a remote in its standard version.

Sony has launched an aluminium-body mobile projector. The gadget is a short-throw, pocket-sized projector that delivers 1080p HD resolution images. It can display a screen size of up to 120 inches at a distance of 3.45 metres. It has a built-in speaker and can be used for home and mobile entertainment, business presentations and for displaying content from smartphones and tablets.

The mobile projector can connect to a source by HDMI, to a mobile device using MHL (mobile high-definition link) or use screen mirroring to display content from a smartphone, tablet device or PC via wi-fi. It has an aluminium body with a matt finish and a 3400mAh battery that delivers up to 120 minutes of HD playback.
