Query: Wet the rubber tip for comfort...

Sound is what matters and out-of-the-box these earphones sound terrific. I tried all rubber tips and settled with the smaller one. Reading the instructions, wetting the tip before wearing them really works! I even used a drop of water-based lubricant and it helped a lot, particularly since I use them for several hours at a time. This earphones are making me use my iPod again, before I used to hate listening to music with those cheap earpods and Apple's headphone amp is just as bad.
