If you find you are routinely using disposable ear plugs to get to sleep then it's worth trying reusable sleeping ear plugs. Foam and wax ear plugs deteriorate over time. With proper care reusable ear plugs on the other hand can last for months. Not only will you get a good nights rest but you'll save money too.
The reusable ear plugs on this page are specially designed to be extra comfortable. No protruding parts or hard materials.
