I recently downgraded from IE8 to Apple IEms and what can I say other then the fact that I am pleasantly surprised by them. Two gripes I had with the IE8 was that 1) they dont isolate at all and 2) their bass is way way too overwhelming. When listening to tunes in public I was just hearing the bass pumping in my ears and nothing else. It just wasnt worth the money when I couldnt even enjoy their soundstage. I said that I downgraded from the IE8... in my opinion I actually upgraded to them. These iems are the most comfortable iems I have ever used. I could wear these for hours without trouble. They are very light, small and stylish. The bass is one of the smoothest bass I have ever heard. The whole sound signature is just very smooth and comforting. On the bus I was actually phasing out into my own world were I was just listening to tunes and relaxing. They isolate very well. This was something I couldnt do with the IE8. I much prefer the whole presentation of the sound to the IE8. The Apple IEMS are very comfortable, easy to use, they isolate very well and their SQ is very very pleasant to listen to. I am very happy that I bought them. I rate the Apple IEM as a low top tier IEM. If anyone is familiar with the sound signature of the PK2 well they share similar sound signatures. I actually have a feeling that SA6, ER4, PFE, AT CK10, q-jays and Apple IEM arent all too different from each other. But these Apple Dual Driver In-Ear Headphones with Remote and Mic can actually been had for 50-60 bucks per pop on ebay. Making them pound for pound a very good IEM. Btw the ipod touch is already the best portable device you can buy. Coupled with these IEMs and that new bluetooth firmware its only going to get better. Excuse the telegram style post.
