There are enough reviews here to pretty much cover it: the in-ear phones are very good if you can get them in and sealed. Having read all about it, I tried and tried with poor results. Finally, I found that my ear canal seems to be about 90 degrees off from the design of the earphones. When I put them in rotated about 90 degrees "up" and a few degrees out, they go right in and stay snug. Great sound, very comfortable. Worth keeping.I agree Apple could do a better job with instrucitons. Just keep in mind your ears may require something different from what you read here.
