Sonos hasn't brought its custom EQ software to the iPhone 14 or 14 Pro when it first came out. But now, it looks like Trueplay has finally made its way to the newest iPhones. Trueplay on many Sonos speakers requires compatible iOS devices to work. And now, iPhone 14 owners can take advantage of the feature. It is still listed as coming to the iPhone 14/14 Pro, but 9to5Mac has spotted it in the wild. They claim the feature even works on the iPhone 14 Pro Max.
