Sonos Ace Ultra FCC Filing Shows Wi-Fi Radio, Pointing to Direct Speaker Integration

An FCC filing for a model labeled "Sonos Ace Ultra" reveals 2.4 GHz and 5 GHz Wi-Fi radios. The original Ace used Bluetooth and a phone as a go-between; native Wi-Fi would let the headphones join Sonos's whole-home audio mesh directly. A September 2026 launch event is expected.
