Making and taking voice and video calls from a laptop is pretty much an everyday activity for knowledge workers these days. Its certainly a must for anyone who does remote working. The earbuds that come with a smartphone are good enough for some, but specialist solutions offer a lot more flexibility. Since trying the , that headset has become my first choice when making deskbound calls. At 249.95 (inc. VAT) the Voyager 6200UC is comparable to the , reviewed here, which I found retailing for 256.80 (inc. VAT).The Sennheiser SDW 5016 is an altogether more chunky beast than the Plantronics headset, and its not intended to be portable. Where the Voyager 6200UC comes with an (admittedly large) rigid case, theres no case here, and the desk stand for the Sennheiser headset is definitely too much for most people to want to carry around. There are actually two versions of this kit. The Sennheiser SDW 5015 has no native support for mobile devices, although this can be added via a Bluetooth dong le. Its less expensive at 242.40 (inc. VAT), but the cost saving is minimal -- and frankly, Bluetooth seems like a must-have to me. The SDW 5000 headset comes with headband, neckband and ear hook fixings. The SDW 5016 model includes a Bluetooth dongle on the base station for mobile phone connection.
