Product story
The Sony WH-1000XM4 wireless over-ear noise-canceling headphones remain an industry benchmark for frequent flyers, commuters, and audiophile listening, pairing 40 mm aluminum-coated Liquid Crystal Polymer (LCP) drivers, Sony's HD Noise Canceling Processor QN1, LDAC Hi-Res Audio Wireless, and 30-hour ANC battery life inside a compact inward-folding 254-gram frame.
Driven by Sony's dedicated HD Noise Canceling Processor QN1 and a Bluetooth Audio SoC working in tandem with dual feedforward and feedback microphones in each earcup, the WH-1000XM4 samples music and environmental noise at over 700 times per second. Using the built-in Personal Noise Canceling Optimizer and an onboard barometric pressure sensor for Atmospheric Pressure Optimizing, the headphones measure acoustic seal around your head, hair, and eyeglasses as well as aircraft cabin pressure at altitude to tailor noise suppression. Switching to Ambient Sound Control in the Sony Sound Connect app offers 20 transparency levels with an optional Voice Focus pass-through.
Inside each earcup, a large 40 mm dome driver with a copper-clad aluminum wire (CCAW) voice coil and an aluminum-coated Liquid Crystal Polymer (LCP) diaphragm delivers deep sub-bass extension and articulate high frequencies spanning 4 Hz to 40,000 Hz in wired mode (and 20 Hz to 40,000 Hz wirelessly over LDAC 96 kHz / 990 kbps). For compressed streaming libraries, Sony's DSEE Extreme uses real-time Edge-AI instrumentation and genre recognition to restore lost high-frequency harmonics.
Smart everyday controls include Speak-to-Chat (which pauses playback automatically when it detects your voice), Quick Attention (placing a palm over the right earcup to hear announcements immediately), an optical proximity wearing sensor inside the left earcup combined with motion accelerometers for automatic pause/resume, 2-device Bluetooth Multipoint, and one-touch NFC pairing on the left earcup. Battery runtime reaches up to 30 hours with ANC on (38 hours with ANC off), with a 10-minute USB-C quick charge providing up to 5 hours of listening via a 1.5A+ AC adapter. Unlike non-folding successors, the WH-1000XM4 folds compactly into its zippered hard travel case alongside a 1.2 m gold-plated 3.5 mm stereo cable (47 Ω powered on / 16 Ω passive) and a dual-prong in-flight airplane adapter.
Before ordering the Sony WH-1000XM4 from any seller in the BiponiBD catalog, confirm the color variant (Black, Platinum Silver, or Midnight Blue), verify that the zippered carrying case, 1.2 m 3.5 mm audio cable, USB-C charging cable, and dual-pin in-flight adapter are sealed inside, and check seller warranty terms.

Helpful answers
Product-specific answers maintained with the catalog information.
Unlike the WH-1000XM5, which only swivels flat in a larger case, the WH-1000XM4 features inward-folding hinges that collapse into a much smaller zippered travel case and includes a dedicated dual-pin airplane audio adapter.
Yes. The WH-1000XM4 supports Sony LDAC high-resolution Bluetooth streaming (up to 990 kbps) as well as simultaneous 2-device Multipoint connections.
Yes. Using the included 1.2-meter 3.5mm stereo mini cable, the WH-1000XM4 works passively (16 Ω impedance) even when the battery is completely depleted, or actively (47 Ω impedance) with ANC and QN1 processing turned on.
A built-in barometric pressure sensor measures cabin air pressure on airplanes and adjusts the QN1 noise-canceling filter accordingly to maintain optimal noise reduction at cruising altitude.
