LOGITEC!H!!!
DH works in the wireless industry, he's used both, and LOVES the Logitec one, way better sound quality and it has windstop, the plantronics one isnt as good for noise reduction and soud quality. He's only used them at work to demo them ect before they sell if you end up not wanting the Logitech tho for whatever reason lemme know i'll buy it from you for whatever you paid plus shipping, thats on his xmas list, he's already got the plantronics one.
