7 More High-Tech Attention-Getters For 2013 (So Far)


Sennheiser Bluetooth Headset

Taking a step closer to unified communications is the Presence UC ML Bluetooth 4.0 headset from Sennheiser. The German audio master includes with its headset a dongle for Microsoft Lync that seamlessly transfers the headset connection from a mobile phone to and from the office computer's softphone. Presence delivers incredible sound, provided it's not too far from the host device. Sennheiser claims a 25-meter range, but our test MacBook Pro delivered far less. The headset contains three mics for optimizing sound quality in noisy or windy environments. The Presence is about average size, and easily hangs on either side from its ear hook. Also included are small, medium and large ear adapters for going commando-style. Spoken status messages for power, pairing and remaining talk time are a nice touch. We especially like the sureness of a sliding power control (with embedded boom mic), but did accidentally it power-off a few times while getting used to the other controls. The $199 kit includes a rigid carrying case with room for the headset with ear hook, dongle and the included microUSB charging cable. Talk time is rated about eight to 10 hours.
