Sony ULT WEAR WH-ULT900N Wireless Noise Cancelling Over-Ear Headphones with ULT Deep Bass Button, 30H Battery, Quick Charge, Multipoint and Clear Calls, Black - WH-ULT900N

Sony ULT WEAR WH-ULT900N headphones in Black are made for listeners who want powerful bass and real quiet in one comfortable design. Press the ULT button to boost the low end and feel the full energy of your music, or switch back for a more balanced sound. Dual noise sensor technology driven by Sony's Integrated Processor V1 reduces surrounding noise on flights, commutes and busy streets. Large 40mm dome-type drivers with neodymium magnets cover a wide 5Hz to 20,000Hz range. Battery life reaches up to 30 hours with noise cancelling on and up to 50 hours with it off, and a 3-minute quick charge gives up to 90 minutes of music. Beamforming microphones pick up your voice for clearer hands-free calls, multipoint connection keeps two devices paired at once, and thermo-foamed cushions mould softly to your ears. A swivel fold design keeps the 255g headphones easy to pack.
