Sony WHULT900NB Black: Power Bass & All-Day Comfort for Daily Listening

The Sony WHULT900NB Black headphones stand out with their focus on deep, customizable bass and advanced active noise canceling (ANC). Part of the ULT Power Sound series, these headphones cater to users who want powerful low end without sacrificing comfort or wireless freedom. A press of the ULT bass button boosts bass response instantly to suit your music or mood. The WHULT900NB Black combines signature Sony features with long battery life for commuters, office workers, and bass fans.

Standout Features: ULT Bass Button & Adaptive ANC

One unique aspect is the dedicated ULT button, which cycles through two bass enhancement modes for an adjustable listening experience. The headphones use Sony’s V1 Audio Processor and advanced dual noise sensor technology, delivering both impactful sound and effective noise cancellation in noisy spaces.

Wireless Flexibility & Battery Life

Reliable wireless performance matters for people on the move. Multi-point Bluetooth 5.2 connectivity and support for LDAC, AAC, and SBC codecs provide flexibility and high-resolution sound. The battery lasts up to 30 hours with ANC on, while a 3-minute quick charge adds 90 minutes of playback.

• Battery Life: up to 30 hours (ANC on) — uninterrupted listening for long journeys or workdays
• Quick Charge: 3 min = 90 min playback — never miss a beat with rapid top-ups
• Switching between devices is seamless thanks to stable Bluetooth 5.2 and multi-point pairing.

Sound Customization & ULT Modes

Personalize your sound experience with ULT bass boost. Cycle through standard, ULT Mode 1, or ULT Mode 2 for more bass, or fine-tune using the 5-band EQ in the Sony Headphones Connect app. DSEE upscaling enhances compressed audio, and LDAC allows for high-resolution wireless listening.

• ULT Bass Modes: Standard, ULT 1, ULT 2 — control bass intensity at a touch
