Sonos Ace Ultra Buyer Guide: What to Know Before Spending $449

Sonos announced the $449 Ace Ultra flagship wireless headphone, scheduled to ship September 29, 2026, adding deeper integration for private home theater listening. Sonos Ace Ultra introduces a new 40mm driver, stronger Adaptive ANC, lossless audio, and spatial audio. The wireless headphones deliver up to 35 hours of battery life with ANC or Aware mode enabled, Bluetooth 6.0, Wi‑Fi, USB‑C and 3.5mm connections, and expanded three‑ or eight‑band EQ controls. Headphone linking and TV Audio Swap move audio between compatible Sonos speakers, soundbars, and Ace Ultra, with Dolby Atmos, TrueCinema, and dynamic head tracking. The model costs $50 more than the original Ace, comes in four finishes, and launches headphone linking as an Early Access feature; some functions require compatible Sonos equipment.
