This FM Transmitter is crystal clear! I can hear the music I'm playing from my phone very clearly through the car radio/speaker system. Usually when I listen to local radio stations, there's sometimes a static but there isn't any at all from device! Decided to try this Transmitter out because I use a lot of Pandora and Spotify and I fell like you have WAY more freedom with what you listen to. Overall, this little device is great and I would highly recommend it to people that like their car speakers, but want to listen to music streaming services like Spotify or Pandora in their car!
