Portable audio with swivel fold design

The Sony WH-ULT900N/W headphones feature a swivel fold design and include a compact carry case for easy transport. Weighing 1.0000 kg, they are built for listeners who want a portable over-ear option with quality noise canceling powered by dual noise sensor technology and a V1 processor.

Deep bass modes and spatial audio

Press the ULT button to select between ULT1 for deep low frequency or ULT2 for ultra-bass response. The headphones also support 360 Reality Audio and personalized EQ settings to shape the soundstage. Buyers who want a neutral reference tuning without bass enhancement should look elsewhere.

Thermo-foaming cushion comfort

Unique thermo-foaming design creates smooth cushions that adapt to the wearer for extended sessions. This specific comfort approach is the deciding factor for users who prioritize long-term wearability over lighter clamp force or alternative pad materials.

Questions about this item

Will the 1.0000 kg weight and swivel fold design fit comfortably in my existing headphone stand and travel bag?

The headphones weigh 1.0000 kg and feature a swivel fold design with a compact carry case included, so they should fit most standard stands and bags designed for full-size over-ear models.

How can I confirm the dual noise sensor technology and V1 processor are active after pairing?

When noise canceling is engaged you should notice a measurable drop in ambient sound; the Sony Headphones Connect app also shows the noise-canceling status and lets you toggle between modes to verify operation.

Does the box include a carry case and cables, or do I need to buy them separately?

A compact carry case is included with the headphones; any additional cables or adapters beyond what ships in the box would need to be purchased separately.
