In my experience, it works very well at focusing my mind on the sounds or tones that are being produced by the earbuds so that other noises become unnoticeable. I can't say for sure that it will drown out every variety of snorer as you will still be able to hear very loud noises. What I liked is that the 10 noises that the earbuds come with seem to have a unique pitch, and I'm thinking that it would be crucial to find the best noise/pitch that matches the pitch of the snoring. I think you would have success.
