I’ve noticed the Sonos Ace on the lowest possible volume step on my iPhone 15 Pro Max and Pixel 8 Pro are quite a bit louder than competing headphones like the Sony WH-1000XM5 and AirPods Max.
When the Ace are at like 5%, that volume is equivalent to around 15% on the Sonys and 20% on the AirPods Max.
Not sure if this is an intentional design decision or not, but given that adjustments at low volume on the Pixel 8 Pro and iPhone barely seem to move the volume up, I wanted to flag it.
