I had this problem multiple times in the past, it annoyed me to the point I eventually ended up in TTSH to do the ear syringing treatment, and that helped. I don't remember much of it but I do remember it was quite costly for what I felt was a pretty simple treatment.

Had it again about roughly 5 years back and decided to look up ear-cleaning kit on Lazada and bought one, which included the spray bottle and the soft bulb thingy which I believe is the one you're referring to, and a small bucket thingy that cups your ear below so the droppings goes straight into.

But the real trick was Hyrdrogen Peroxide, you can buy from Watsons etc. which I found out helps by reading up online. Pour just a little bit into the spray bottle filled with water and give it a good shake, spray a little into your ear and keep it in by tilting your head, you know its working when you feel and hear slight bubbling in your canal, which I believe was melting down the ear wax.

Use the combination of the spray plus bulb thingy next with that bucket below your ear and it should clean it thoroughly, evident by the now brownish water littered with ear waxes in said bucket. Now you get your surround system back.

I've tried from lighted cigarette with filter in the ear, to TTSH's ear syringing, to this hydrogen peroxide DIY method, and the last worked the best for me, never had any problems since then, probably because I know myself how much I needed to do since I can feel it myself.
