Has anyone else noticed how Ed Sheeran doesn't use autotune?

Ed Sheeran doesn't use autotune, I've noticed. I've seen him live, and he sounds exactly the same as what he does when you're listening to him on the radio. I can tell he doesn't just lip sync to his songs when he performs, because you can hear the large intake of breath while he sings, which is the only thing he covers up on tape. Has anyone else noticed this?
