I'm worried my IEM days are numbered. I've noticed that my ear canals are of different shape. I'm 43, and just 6 or 7 years ago it was no problem to wear any style of IEM. Now, very few IEMS can deal with my right ear, the canal of which seems to have become more curved than the left. I know that ear canals are curved anyway, but I'm talking about an increased curve. As our bodies age and contort like old trees, I guess.
Some IEMs (Klipsch, or narrow-bore barrel types) just get the sound totally cut off when the end of the tip gets pinched inside, maybe, or come up against a surface. For others, the bass gets really attenuated on the right (maybe because of the way bass frequencies travel around curves? I don't know). So the result in that case is this feeling that the music is weighted towards the left, which is a really annoying sensation. I've tried deeper insertion, and pushing the tips down further over the nozzle than they're supposed to go, and angling them, but nothing really works.
It doesn't happen with over-the ear headphones for some reason. I've got about 15 hours on my Auglamour AG-R1s, but I'm going to have to sell them because I can't get the right ear to fit for the bass frequencies. In all of these cases I've done some basic testing, and it's definitely the shape of my ear canal, and not the IEMSs themselves being faulty, or my actual hearing in the right ear being weaker in perceiving bass.
Does anyone knowledgeable about IEMs have any helpful input here in terms of what to avoid and what might work? I'm realizing that the buy-and-try method is just going to be too expensive if I have to keep selling IEMs that don't work for me. Or maybe I have to give them up entirely? The B3 Pro I's seem to be fine, but I wanted to get something that didn't need an amp, perhaps something with
sightly more bass for walking and hiking, but neutral and spacious still.
