Sony ULT WEAR Wireless Over-Ear Noise-Canceling Headphones (Black) WHULT900NB
The Sony ULT WEAR Wireless Over-Ear Noise-Canceling Headphones (WHULT900NB) represent a specialized evolution in premium personal audio, engineered specifically for listeners who prioritize deep, resonant bass and high-energy sound profiles. As part of the ULT Power Sound series, these headphones bridge the gap between audiophile-grade noise cancellation and the visceral acoustic pressure required for modern electronic, hip-hop, and bass-heavy genres. The sleek black finish and ergonomic over-ear architecture ensure a professional aesthetic that complements its advanced technical capabilities.
The core identity of the WHULT900NB centers on its dedicated ULT button, which allows users to cycle through two distinct low-frequency enhancement modes. The first mode emphasizes deep, lower-frequency resonance for a cinematic vibration, while the second mode provides a punchy, high-attack bass that increases rhythmic drive. Large 40mm driver units, specifically tuned for the ULT series, maintain high-fidelity mid and high ranges even while delivering extreme low-end output. This balance ensures that vocals and instrumentation remain crisp and distinct against a backdrop of powerful sub-bass frequencies.
Sony integrates the high-performance Integrated Processor V1 into the WHULT900NB, the same technology found in the award-winning 1000X series. This processor works in tandem with a Dual Noise Sensor system to capture and neutralize ambient environmental sounds across a broad spectrum. Whether suppressing the low-frequency hum of an airplane engine or the chatter of a crowded office, the headphones provide a silent canvas for music playback. The system includes an adjustable Ambient Sound mode with 20 levels of transparency, allowing listeners to stay aware of their surroundings without removing the headset.
Engineered for extended listening sessions, the WHULT900NB features soft, pressure-relieving ear cushions that create a secure acoustic seal while maintaining comfort. The headband design optimizes weight distribution to prevent fatigue during long commutes or workdays. A built-in capacitive sensor enables smart wearing detection, automatically pausing playback when the headphones are removed and resuming once they are placed back on the ears. The foldable structure allows the unit to collapse into a compact form factor for easy storage in the included carrying case.
The WHULT900NB utilizes Bluetooth 5.2 technology to support high-resolution wireless audio via the LDAC codec. Multipoint connection capabilities allow the headphones to pair with two devices simultaneously, enabling seamless switching between a smartphone call and a laptop video conference. Users can further customize their experience through the Sony | Headphones Connect app, which offers granular EQ adjustments and sound stage optimization. Voice assistant compatibility with Google Assistant and Amazon Alexa provides hands-free control over playback, notifications, and smart home integration.
Power management on the WHULT900NB is designed for heavy users, providing up to 30 hours of continuous playback with Active Noise Cancellation (ANC) enabled. Disabling ANC extends the battery life to an impressive 50 hours. The quick-charge feature provides 90 minutes of playback from a mere 3-minute charge, ensuring the device is always ready for use. In alignment with environmental initiatives, Sony constructs the ULT WEAR headphones using recycled plastic materials and plastic-free packaging, reducing the ecological footprint of the manufacturing process.
