A year later, the Sonos Ace is finally fulfilling its potential

Here is a 191-word summary of the news article: A year after their release, the Sonos Ace headphones are finally fulfilling their potential with a major software update. The update includes the long-awaited TrueCinema spatial audio feature, which uses the acoustics of the room where a Sonos soundbar is located to create a more immersive, 3D audio experience. This significantly enhances the Ace's TV Audio Swap feature, making it the optimal mode for watching movies and TV. The update also adds two-person TV Audio Swap, allowing two sets of Ace headphones to receive audio from a Sonos soundbar. Additionally, the Ace's active noise cancellation and call quality have been improved, with better real-time adaptation to changes in fit and a new sidetone feature for natural-sounding calls. While Sonos faced challenges in 2024 with a botched app launch and product delays, the company has continued to support and improve the Ace. The headphones are now available at a $149 discount from their original $449 price. Overall, the latest updates have helped the Ace live up to the high expectations Sonos set when it first launched.
