With the Sony WH-L600, you can enjoy high-quality sound while watching your favorite movie or series. You can connect the transmitter to your television and this will send the audio signal to the headphones, allowing you to listen to the movie sounds wirelessly from the couch. Thanks to Cinema Mode, you can create a surround sound effect, giving you the feeling of sitting in a movie theater. You can use the headphones for 17 hours on a fully-charged battery. The indicator light will come on when it's time to charge the device on the station.
