WAHL has really good Clippers and they are relatively quiet, and much less expensive.

Hello there Allison! I’m attaching a video I took of my husband using the clippers on our son so you can have an idea of how much noise it makes. My husband uses Wahl Elite Pro. As you can see he cuts our son’s hair really short, he also lets him listen to his favorite music while he’s working on him. I hope this helps!

Yes, my husband uses WAHL. 👍🏽

I used Little Martin's Drawer hair trimmers on both my asd sons. They actually tolerated it because very quiet and gentle. Only downside is the longest length isn't very long. It was a stepping stone to Wahl trimmers.

Here's the link. I hope that helps!
