RadTech today began shipping its BT400GL in-ear Bluetooth headset with noise-suppressing DSP technology. The headset weighs 8.5 grams and measures 39mm long, delivering 350 hours of standby and more than 15 hours of talking time. The compact in-ear design injects sound into the ear canal while blocking extraneous noise, and three sizes of ear tips feature new Nano anti-bacterial rubber. A companion power cradle -- which is small enough to fit in a pocket or purse and is wearable about the neck via a lanyard -- stores the headset when off the ear, and features a silent vibrating alert. The BT400GL works with any phone or device supporting the Bluetooth audio, headset, or handsfree profiles (versions 1.1 and 1.2) and ships in silver or pink for $65.
