Why choose Comply™ 100 Series Tips?

  • Comfort that lasts: Memory foam adapts to your ears for a pressure-free, all-day fit.

  • Noise isolation: Foam expands in the ear canal to block outside distractions and enhance audio at lower volumes.

  • Device protection: TechDefender™ foam barrier keeps sweat, wax, and debris out of your earbuds.

  • Backed by our 100% Guaranteed Fit Program.

Tip Lifespan: Each pair typically lasts 2–3 months depending on use and care. Avoid alcohol-based cleaners or lotions to extend their life. Replace tips when they start to flake, tear, or lose their slow-rebound memory.

Perfect Isloation - Superb SOund Quality

I bought these Comply tips based on recommendations I found on an audio forum. I use the large size tips with my Sony Player. The big test is when I go on the Toronto subways system. I was very impressed with the results. These tips provided complete isolation and produced a superb listening experience. I could not hear the subway train at all.

They are also very comfortable and easy to wear for long periods of time. This product is a winner.

Works well, I was relieved

When I saw QuietOn sleep ear phones had been sold to a Canadian company I was worried about getting ear foam replacements, I was not sure what I was going to get with Comply. It has been a pleasant surprise, the replacement foam ear tips are better than the originals, better fit, better sound barrier as well. Thanks!!!

Stop looking, you found the one!

After trying several other brands, the Comply tips are the best I’ve found so far.
Very easy to get a good seal, and extremely comfortable.
Highly Recommend!
