Jabra BT800 brings some very advanced features not seen before to the Bluetooth headset segment. It sports blue backlit LCD display used for Called ID, battery status indication and menu browsing. The headset also utilized DSP technology used to suppress Wind and ambient noises. During the performance testing, BT800 demonstrated exceptionally long range and sound clarity. The continuous talk time achieved was 6 hours - exactly what the specifications calls for. Given all the advanced capabilities, the design is inevitably bulkier with weight of about 0.8 oz. Wearing the headset for short periods of time does not create discomfort, but I do not recommend having it on for more than 1 hour.
