Sony Ult Wear Wh ULT900N

The Sony ULT WEAR (WH-ULT900N) wireless over-ear noise-canceling headphones are the direct successor to Sony's Extra Bass WH-XB910N series, combining custom 40 mm neodymium drivers, Sony's flagship-derived Integrated Processor V1, dual-stage ULT1 / ULT2 POWER SOUND bass modes, LDAC Hi-Res Audio Wireless, and up to 30 hours of ANC battery life inside a foldable 255-gram chassis.

Custom 40 mm drivers, Integrated Processor V1, and ULT1/ULT2 bass modes

Engineered for bass enthusiasts, hip-hop, electronic music, and movie streaming, the WH-ULT900N uses a newly developed 40 mm dome driver unit with high-compliance diaphragm geometry spanning 5 Hz to 20,000 Hz (and up to 40,000 Hz over LDAC 96 kHz / 990 kbps). A tactile ULT hardware button on the left earcup cycles between ULT Off, ULT1 (which emphasizes deep, low-frequency sub-bass resonance), and ULT2 (which boosts upper-bass punch and dynamic sound pressure). Pairing with the Sony Sound Connect (Headphones Connect) app unlocks a 5-band custom equalizer, a dedicated Clear Bass slider, DSEE upscaling for compressed streams, and 360 Reality Audio with head tracking.

Dual Noise Sensor ANC, Wind Noise Reduction, and Ambient Sound control

Each earcup houses two noise-sensing microphones (feedforward and feedback) driven by Sony's Integrated Processor V1—the same low-latency processor used in the 1000X series—to cancel commuter bus, train, and office air-conditioning noise. A physical Wind Noise Reduction mesh structure surrounds the exterior microphones to minimize wind buffeting during outdoor walks and voice calls. Pressing the NC/AMB button switches to Ambient Sound Mode (adjustable across 20 transparency levels with optional Voice Passthrough in the app), while covering the right earcup with your palm activates Quick Attention to lower music volume instantly for face-to-face conversations.

30-hour ANC battery, Multipoint Bluetooth 5.2, and foldable travel case

Weighing 255 grams, the WH-ULT900N uses smooth thermo-foaming synthetic leather earpads that mold around eyeglasses, a capacitive touch control panel on the right earcup, and an internal capacitive wearing-detection sensor that pauses playback automatically when removed. The battery delivers up to 30 hours with ANC on (up to 50 hours with ANC off), and a 3-minute USB-C quick charge adds up to 90 minutes of listening. Unlike non-folding headphones, the WH-ULT900N folds inward into its bundled zippered hard carrying case alongside a USB-C charging cable and a 1.2 m 3.5 mm stereo cable (usable powered on at 314 Ω or passively powered off at 32 Ω).

Bangladesh buyer checklist

Before ordering the Sony ULT WEAR (WH-ULT900N) from any seller in the BiponiBD catalog, confirm the exact color variant (Black, Off-White, or Forest Gray), verify that the zippered hard carrying case, USB-C cable, and 1.2 m 3.5 mm audio cable are sealed inside, and check seller warranty terms.
