If you are long time Poly (formerly Plantronics) headset user, you may have noticed that the SKU's (part numbers or item numbers) have changed. In August of 2022, HP purchased Poly and promised not to change anything for One Year. That year is now up and we are seeing a roll out of all new SKU's that conform to HP's current numbering system. Please be patient with us while we complete the process. We are also seeing delays in product availability during this time. If you don't see an item in stock, please Chat, Email or Call us, as it may have arrived under the new SKU and we haven't updated the website yet.
