Loud and clear The RS 180 (below) is Sennheiser's top-of-the-range, plug-and-play wireless headphone set. It has a range of 100 metres from any television, stereo system or digital-video player the device's transmitter is linked to. The transmitter also functions as a charger and docking station for the headphones, which have soft, padded ear cups and an adjustable headband. The company says the so-called open 'circumaural' design delivers clear, high-resolution playback. The RS 180 sells for HK$2,880. Kick up a storm The BlackBerry Storm 2 (above right) is the latest version of Research In Motion's first touchscreen smartphone, released last April. Its high-resolution 3.25-inch display uses an update of the proprietary SurePress technology, which provides the sensation of 'clicking' virtual keys. The improved interface allows users to type a letter with one thumb even while the other is resting on another key, enabling faster typing. The 3.5G smartphone has a 3.2-megapixel camera, Wi-fi and Bluetooth support, a built-in Global Positioning System link, two gigabytes of onboard storage and a memory-card slot that supports cards of up to 16GB. The device allows for easy syncing of audio files from Apple's iTunes and Microsoft's Windows Media Player. Available from CSL's 1010 and one2free, and 3 Hong Kong shops, the Storm 2 is priced at about HK$4,600. Green piece The Vaio VPCW21EAG (below) may be Sony's most eco-friendly laptop to date. About 80 per cent of the plastic parts used in its top cover, palm rest and case are recycled, which, the company claims, results in a 10 per cent reduction in the amount of carbon dioxide emitted during the production process. In lieu of cardboard packaging, the VPCW21EAG comes in a carrier bag partially made from recycled plastic bottles. It features a 10.1-inch display, an energy-efficient Atom N450 processor from Intel, a 250GB hard-disk drive, a six-cell battery and Wi-fi support. It has a white finish, mint green palm rest and patterned touch pad. The Vaio VPCW21EAG costs HK$3,980.
