Title: Don't Recommend
Review: I bought one of these today and spent hours trying to make it work. Even at my cell phone's highest volume setting I can barely hear someone on the line while sitting in an absolutely silent room, let alone in a car. This product might work if it was plugged into an amplifier, but as it is, I don't recommend it. Even if it had all the volume in the world I would still have given it only three stars because I never did find a physically comfortable position to wear it. And, the test calls that I made ended up with the people on the other end not being able to hear me either. This product is one of those where you get what you pay for. Buy something more expensive.
