Negative Positive
Title: Static on the other end
Review: I am using this device with a Polycom landline phone.Trying the 3 settings I can get a decent connection on my end with a separate Bluetooth earpiece, where I hear the other party fine with little noise and no echo.But on the far end, even landline to landline, there is an annoying whine and some echo, no matter what the setting. This isn't good enough, I prefer to use the corded headset.I am returning this product to Amazon.
