Slim and sleek for total comfort With super-slim ear pads and a silicone headband that fits closer around the head, these headphones stay comfortable all-day long. Light and compact, they fold up when not in use for easy storage in a case or bag. Dual Noise Sensor technology Dual noise-cancelation microphones-one feed-forward and one feed-back-on the surface of the headphones catch more of the ambient sounds of your surroundings, whether it's in-flight noise, city traffic or office chatter. Adaptive Sound Control automatically adjusts to whatever you do The Sony | Headphones Connect app offers Adaptive Sound Control, a smart function that automatically detects what you're up to-such as traveling, walking, or waiting-then adjusts ambient sound settings to suit the situation. You can also customize the settings to your preferences. Quick Attention lets you chat Need to have a quick conversation? Hold your hand over the touch sensor and the music quietens while sound from your environment gets louder. 0.98 " driver unit Small but powerful 0.98 " drivers with highly rigid aluminum domes and soft urethane-edge diaphragms achieve the same sound pressure as conventional 1.57 " drivers - ideal for reproducing a full range of frequencies from low beats to soaring vocals. Truly authentic sound Enjoy the subtle nuances of studio-quality sound in higher than CD quality with High-Resolution Audio. Passion for music unites every component from signal to speaker, so it feels like the artist is performing right in front of you. Better BLUETOOTH® audio LDAC transmits approximately three times more data (at the maximum transfer rate of 990 kbps) than conventional BLUETOOTH® wireless audio, allowing you to enjoy High-Resolution Audio content in exceptional quality, as close as possible to that of a dedicated wired connection.
