A word of caution about the "fizzing" eardrops.
I've had my ears syringed between 2 and 4 times/year for the last 30 years or so, originally with a huge metal syringe that looked like a device for inseminating cows (but which worked very quickly and well) and latterly with the pulsing widget that others have described (which works eventually, providing the was is well softened with olive oil).
A few years ago I decided to try some ear drops that promised to dissolve the wax, but once the heating and fizzing was over I was left deaf and in moderate pain. My GP couldn't see anything wrong but referred me to an ENT specialist who found that the wax had become transparent and was mostly pooled at the bottom of my ear canal and pressing on places that don't like being pressed. He then used a suction device to remove it all - bliss!
The next time I got blocked-up I went back for a good sucking but it was quite expensive; since then I've gone back to being syringed.
I'd prefer to avoid such frequent syringing but would not risk the "fizzing" eardrops again - beware!
OT: several years ago I was in Budapest and suddenly got severe ear pain. The hotel called an ambulance (rather OTT) when I asked where I should go and I was eventually escorted to the local big hospital and marched past all the waiting peasants (literally!) to see the head ENT honcho - complete with mirror fixed to his forehead. Over the next 30 minutes he used a set of wires to remove a huge mount of wax from both ears - slightly worrying at the time, but bliss afterwards.
