The Sonos Ace Ultra headphones represent a significant evolution from the original Ace model, showcasing a more refined and robust listening experience. They address key areas for improvement, delivering enhanced audio performance, superior noise-cancelling capabilities, and extended battery duration. This new iteration also deepens its integration within the Sonos ecosystem, notably through the innovative Headphone Linking feature, making it a compelling choice for existing Sonos users and audiophiles alike.
Sonos Ace Ultra: A Comprehensive Review
Launched in September 2026, the Sonos Ace Ultra headphones have arrived, following the successful yet not groundbreaking debut of their predecessor. These new over-ear headphones, priced at £399/$399/€399, aim to solidify Sonos' position in the competitive audio market, leveraging two years of development to refine user experience and sound fidelity. Key enhancements include improved sound detailing, more effective noise cancellation, and a battery life extended to 35 hours, all while maintaining the ergonomic design that made the original so comfortable.
The design of the Ace Ultra remains largely consistent with the original, emphasizing comfort and a sleek aesthetic. Users will appreciate the snug fit, even for glasses wearers, and the thoughtful inclusion of physical controls over touch-sensitive alternatives. A notable design element is the continued use of detachable earcups and a replaceable battery, extending the product's longevity and user serviceability. New color options, Agave and Sand, add a touch of personal style, departing from the classic black and white. The travel case, while stylishly branded, still features a somewhat cumbersome zip, and the magnetic cable case ensures all accessories are neatly organized.
Connectivity is upgraded to Bluetooth 6, supporting SBC, AAC, and aptX Adaptive codecs, ensuring stable connections even in bustling urban environments. The refreshed Sonos app, a direct response to earlier critiques, now offers a more responsive interface with advanced EQ settings, allowing users to fine-tune bass, treble, mids, and even adaptive EQ based on fit. A unique aspect is the app's reliance on Wi-Fi for settings adjustments, which might be inconvenient when out of range. The Ace Ultra also features Dolby Head-Tracking for immersive audio and introduces 'Headphone Linking,' an early access feature that allows seamless audio transfer between the headphones and any nearby Sonos speaker—a true game-changer for Sonos ecosystem users, despite initial minor delays in switching.
Battery performance has seen a commendable boost, delivering a verified 35 hours of playback with ANC enabled, surpassing Sonos' claims in some real-world tests. Rapid Charging provides three hours of listening from a mere three-minute charge, and a Power Saving Mode is available for extending usage, though it restricts some advanced features.
The noise cancellation on the Ace Ultra is significantly improved, offering robust suppression of ambient noise across various environments, from crowded streets to airplanes. While it might not entirely eclipse industry leaders like Sony and Bose in sheer noise-squashing power, its natural-sounding Aware Mode and effective handling of wind noise are standout features. Call quality, however, remains an area for potential improvement, with voices occasionally sounding muffled against background noise.
In terms of sound quality, the Ace Ultra features new 40mm custom dynamic drivers that deliver a more detailed and dynamic sound profile compared to its predecessor. While the headphones offer a comfortable, balanced listening experience with weighty bass and clear midrange, some audiophiles might find them less 'musical' or expressive than offerings from Sony or Sennheiser. The ability to connect via USB-C for lossless audio up to 16-bit/48kHz provides an even richer, more spacious sound, demonstrating the headphones' true potential when paired with high-quality sources.
Ultimately, the Sonos Ace Ultra builds on a solid foundation, offering a refined, feature-rich experience that deeply integrates with the Sonos ecosystem. It stands as a strong contender in the premium wireless headphone market, particularly for those already invested in Sonos products, promising an evolving experience as Sonos continues to innovate its software platform.
Embracing the Ecosystem: A New Era for Sonos Headphones
The launch of the Sonos Ace Ultra not only refines the hardware experience but also signifies Sonos's strategic pivot towards a more deeply integrated ecosystem. The 'Headphone Linking' feature, while in its nascent stages, points to a future where personal audio devices seamlessly interact with home audio systems. This evolution encourages users to view their Sonos devices not as isolated gadgets, but as interconnected components of a unified sound environment. From a user's perspective, this means greater convenience and a more fluid audio experience across different settings. As a reporter, I believe this emphasis on ecosystem integration is a smart move, setting Sonos apart from competitors who often focus solely on individual product performance. The Ace Ultra represents more than just a pair of headphones; it's a testament to Sonos's vision of a holistic and connected audio future, challenging other manufacturers to think beyond standalone devices and consider the broader implications of interconnected audio. The ongoing refinement of the Sonos app and the promise of future integrations suggest that this is just the beginning of a truly compelling journey for Sonos users.
