there was a topic bout headsets awhile back and my dsp 500 jus not finnally went on me it still works but sometimes the cord moves the wrong way it will go in and out so i decided to shop for a head sets its been 3 years since i bought my dsp500 and i found this on plantronics website something not very advertised

http://www.plantronics.com/clearance

dsp500 is on there for only 25 bones and theres alot of hs on there that are like 10 bucks lol these are good head sets just old ones and plantronics distributing the same heads just with different names and paints for double the price



purchasing on there website was a bitch for me tho hope u have better luck i had to call there 800 and have some hotty walk me through it
