Mine finally arrived today, interesting that I had the opposite experience with the ear tips. The stock mendium ones were big enough that I couldn't get it to firmly stay in the ear canal and would slide out, and that made it so that I couldn't get the bud to sit within my ear at all. I ended up switching down to the small, and then the extra small. It doesn't feel loose, and I haven't tried jogging with it. I think I will try to go with X-small until I have problems with it falling out. It just seems much easier to not "feel" them pressing into my ears that way. Fit aside, I think they sound pretty good.
I was having some of the crackle sounds that people had mentioned in previous threads, but haven't noticed it much the last half hour or so. These may require some actual break in time. It could also have been just moving the cable around or the connector.
I will not try describing the sound since I have a hard time even finding what I prefer yet from adjusting the equalizer. It is a very clean sound though, and I am fairly happy with it. I think the best part of the product is the craftmanship, the presentation, and all the extra goodies included. These were what really sealed the deal for me. The little travel case will help extend the life on these I am sure just by preventing cable bending and tangles when traveling. The single button on the mic also works great to answer, end, or dial on the phone. I would definitely buy them again, great value for the price.
