No don’t do it! I’ve found that just about anything outside of Nature put in the ear canal can cause irritation. I don’t know what kind of injury your ear canal had, but be VERY careful about trying to glue a tip onto the receiver. Even that may fall off.
I’ve had both the tiny wax guard AND a silicone tip come off in my ear canal on different occasions years apart. The wax guard literally worked its way to the doorway about 6 mos after it fell off in my ear. My audi plucked it out with tweezers.
I was responsible for my silicone tip coming off in my ear canal cuz I hadn’t seated it on the tip of the receiver. Now, when I change the silicone tips, I put my dang READING glasses on, hold the tip nice and firm, and make sure it’s seated onto the receiver before putting my aids in.
It kinda took my breath away when the tip was stuck in the doorway of my ear canal, but I just took a few deep breaths and squeezed my ear with one hand, then plucked the tip out with the other.
As to the PAIN of music, get the Music program set up as others have recommended. It is a game changer for those who love music: rock, country, classical, jazz - you get the true dynamic range as best as the aids can deliver. I even put my aids into the Music program if the Noise Management is too aggressive. It kind of turns the aids into “DUMB ears” that don’t mess with volume no matter whether you’re in wind, at a concert, or even a noisy place.
