The Sony WH-ULT900N is an over-ear, closed-back wireless headphone with noise canceling. It uses dual noise sensor technology and Sony's noise canceling, which is also found in its 1000X series headphones. It has 40mm drivers with neodymium magnets.
An ULT button adds two kinds of bass emphasis. One is a powerful bass for feeling the beat. The other is a deep bass boost for a more relaxed sound.
The ear cushions are molded and made with a thermo-foaming process for a snug fit. The headphones swivel and fold into a compact shape and come with a carry case. They connect to two devices at once over Bluetooth and switch to the right one during calls. Battery life is up to 30 hours, or up to 50 hours with noise canceling off. A 3-minute charge gives 90 minutes of extra playtime.
