We like the look of the Plantronics Pulsar 590 Bluetooth stereo headset — something about that retro-DJ style really hooks us. But do they work? And how well do they sound? Turns out they get the job done mighty well, according to Ron Harris of the AP. He tried out a set, both with and without the optional dongle, and found that they produced "killer sound," and worked well with a range of devices from a DVD player to an Xbox. Unfortunately, he apparently didn't test them with a phone, so we don't know how well the mic worked. But we've heard enough to convince us that these are at least worth checking out when the rest of us get to look at them in October.
