I have a Plantronics Head Set model WO2 I used at work back in 2015 at my work station and haven't used since then when I moved from Southern CA to Northern CA. I retired in May 2020 and no longer have a use for this item since it's been sitting in my closet since 2015. The same new item sells for over $200 in Amazon. Asking $40 shipped. Paypal. SOLD to Ozarkboy.
