Works
The JBL Reference 510 reduces outside noise by up to 70% through its active-noise
canceling circuitry. Embedded in the headphones are miniature microphones that measure
the environment’s sound levels. Based on those measurements, the noise-canceling circuit
cancels or reduces any unwanted sounds. As you can see in the graph below, the JBL Refer-
ence 510 smoothes out the high and low peaks of noise from the outside world, making
your music-listening experience or quiet leisure time interruption-free.
