Excessive earwax (that sometimes hardens) and debris can be washed out of the ear (either in the shower or with one of those bubble-syringes used to blow water into the ear that comes with most ear cleaning kits).
With bass heavy Rap and Hip-Hop, I can say I prefer the 846. However, with most of my music (where vocals are more important), I still prefer the 535 (at least with my current source). I'll see how it goes once I “upgrade” my portable source.
I am surprised you feel that way Truck having owned the 535 for a year and now the 846 for three weeks. I find the 535 a bit hollow sounding compared to the 846. I listen to everything from Prog Rock to symphonic and the clarity and the depth of the 846 far exceeds my 535. I loved my 535 up until the moment I started listning to the 846. The 535 is like a beautiful house without a basement and until I heard the 846 I never realized what I was missing. I felt like Spyro that the 535 had pleanty of bass until the 846.
I also thought the 535 had the best midrange in a universal IEM. I remember reading a comment by Flavio at Earphone Solutions that after listning to the 846 he found the 535 midrange fatiguing at times especially with female vocals. Now again I loved the 535 midrange but after listning to the 846 for three weeks I have to agree with Flavio.
My advice Truck instead of upgrading your portable source look into a balanced amplifier. Ray Samuels Protector balanced amp was the biggest improvement to 535 sound and now my 846. Your preference for the Galaxy 4 over the iPhone 5 may be because of the extremely low input impedance of the 846 (9ohm I believe). An amp changes all that because it becomes the output impedance of the amp that matters not the source.
