The Plantronics Discovery 655 Bluetooth headset is an upgrade of the previous Discovery 640 series. Like the previous two models, the 655 still has multiple charging options, and it maintains the same silver and black finish. There are a few differences, however, as we'll note later. The headset is retailed at a hefty $149.95, but you do get an excellent headset for the price.
The 655 is a bit more slender than its predecessors. Instead of the same cylindrical shape of the previous models, it has a more tapered form factor. It's also reasonably compact at only 0.6 by 0.5 by 2.0 inches and weighs a slight 0.3 ounces. Yet like its predecessors, the 655 fits directly in either ear with a rubberized ear gel. Overall the fit was comfortable and secure, and it even comes with two additional earbuds in different sizes. While there is an optional ear hook for increased stability, we preferred to go without it--the fit was tight and uncomfortable.
