Details: One of the first in-car speakerphones to have 3 speakers coupled with Virtual Surround Sound. Sound so clear, you'll think you're talking to a passenger in the car. Also great for playing your favorite music. Prefer your car's sound system? Just use the FM transmitter to send music and calls directly to your car radio. Dual-mic technology filters out everything but your voice. Background noises and honking cars disappear, so the other side hears you loud and clear.
