This product's microphone doesn't pick up my voice very well, and injects a lot of hiss. The few times I've used it, I've had to switch to the handset in order for people to understand me. I'd use it if I had to make a call in the car -- where I can talk loudly and I need my hands free -- but not otherwise. This is really disappointing, since my wife has a different model Motorola headset and it's clear as a bell.
