ModeLabs has announced its Bluetrek Metal headset, which is only 4 mm thick, thus its one of the slimmest headsets on the market, and it's even light: it weighs only 5.5 grams. The small size of the accessory means no problem for its uptime: it has a standby time of up to a week or a talk time of 5 hours with one charge. The headset is so small due to its thin, but still hard metal case. The extremely light headset needs no headband for fastening, as its plug fastenes it perfectly. Bluetrek Metal is to be launched in June in France. The black-silver aluminum edition will cost €39 EUR, while the steel edition will have a price-tag of €49 EUR.
