The best success I've had getting earwax out is by getting any kind of cheap plastic syringe (20ml+) and a plastic bowl, filling the bowl up with warm water from the shower, leaning into the shower or over a bathtub and just blasting shots of warm water into my ear for about 15 minutes.
For the first few minutes it'll seem like nothing's happening, but the warm water will be softening the wax and then suddenly you'll get huge clumps coming out and you'll be like, how the hell did all of that fit in my ear? And then you just keep going, probably longer than you expect, until you can feel the water hitting your eardrum unobstructed - if your ears are as bad as mine get you'll easily be able to feel the difference. Any other softening methods beforehand will help, but I don't bother and it probably only adds a few minutes to the whole process. I usually feel dizzy for a few minutes afterwards though, so if you get that don't worry!
