I have had no problems with this headset. Before you buy it check with Plantronics.com web site to make sure it will work with your cell phone or cordless phone. I am using mine with a Uniden TRU 6455 phone and it works great but won't work with my cell phone.These are perfect for the times your spouse goes out of town for a while and you spend an hour getting caught up on what went on that day! It keeps your arm from going to sleep and you can do other thing at the sametime with two hands!Every one should have one of these and Amazon has a great price.
