        Thank you for your honest review on our CS540 headset system, we are sorry to hear you're experiencing trouble with this unit.

        If you find the over the ear wearing style to be uncomfortable please try using another eartip size or the over the head headband to see if this improves comfort. Please don't hesitate to contact our customer care group at if you require assistance! Plantronics
